[0200] FIGS. 15-20 illustrate example impact shell assemblies for a humanoid robot, including impact shell components configured to at least partially define an outer shape of the humanoid robot and to provide passive impact mitigation while protecting underlying components from intrusion and contact. In certain embodiments, the impact shell assemblies are positioned over major regions of the humanoid robot and are configured to cooperate with other exterior coverings, including a fabric layer and / or an outer suit layer, to provide a selected exterior geometry for operation in human environments.

[0201] Referring to FIG. 15, an example impact shell assembly is shown for an upper portion of the humanoid robot. In the example shown, the impact shell assembly includes a torso impact cover 1501 configured to at least partially define an outer shape of a torso assembly. The impact shell assembly further includes an upper arm impact cover 1503, an elbow impact cover 1505, and a lower arm impact cover 1507 configured to at least partially define outer shapes of corresponding arm regions. In certain embodiments, the upper arm impact cover 1503, the elbow impact cover 1505, and the lower arm impact cover 1507 are sized and arranged to maintain impact protection across a range of motion of an arm assembly while reducing exposure of underlying joint mechanisms. The impact shell assembly further includes a hip girdle impact cover 1509 configured to at least partially define an outer shape of a hip region and to provide impact protection adjacent to a torso-to-leg transition region.

[0202] Referring to FIG. 16, an example impact shell assembly is shown for lower-limb regions of the humanoid robot. In the example shown, the impact shell assembly includes an upper leg impact cover 1601, a knee plate 117, and a lower leg impact cover 1603. In certain embodiments, the upper leg impact cover 1601 and the lower leg impact cover 1603 define exterior surfaces of corresponding leg regions, while the knee plate 117 provides impact protection at a knee region and is configured to cooperate with adjacent shell components to accommodate knee articulation.

[0203] Referring to FIG. 17, an example head assembly is shown. In the example shown, the head assembly includes a head back plate 103, an ear panel 105, an eye 125, and a face plate 127.

[0204] Referring to FIG. 18, a rear view of an example humanoid robot structure is shown. In the example shown, a plurality of impact shell components are arranged across the torso, arm, hip, and leg regions to provide an exterior defined at least in part by the impact shell assemblies. The headAttorney Docket No. ONEX-0008- WOassembly is further shown including the head back plate 103, the ear panel 105, the eye 125, and the face plate 127. In certain embodiments, the arrangement shown in FIG. 18 illustrates region-to-region continuity of impact protection along the body of the humanoid robot.

[0205] Referring to FIG. 19, a rear perspective view of an example humanoid robot design is shown. In the example shown, the exterior geometry is defined at least in part by impact shell components across the torso, arms, hip, and legs, with the head assembly shown including the head back plate 103, the ear panel 105, the eye 125, and the face plate 127. In certain embodiments, the view illustrates exterior contouring of the impact shell assemblies to provide a human-like silhouette while maintaining impact protection.

[0206] Referring to FIG. 20, a side view of an example humanoid robot is shown. In the example shown, the side view illustrates an exterior profile defined at least in part by impact shell components across the torso, arms, hip, and legs, and further illustrates the head assembly including the head backplate 103, the ear panel 105, the eye 125, and the face plate 127. In certain embodiments, the side view shows how the impact shell assemblies are shaped and positioned to accommodate joint articulation while maintaining a selected outer geometry suitable for operation in human environments.

[0207] Referring to FIG. 21, a humanoid robot includes a hip girdle 2101 disposed at a lower torso region adjacent a torso-to-leg transition region. In certain embodiments, the hip girdle 2101 at least partially surrounds a lower portion of a torso assembly and extends toward upper portions of one or more leg assemblies to provide exterior coverage across a region that experiences relative motion between the torso and the leg assemblies.Referring to FIG. 35, the hip girdle 2101 includes a girdle mesh 3503 and a girdle flexible separation 3501. In certain embodiments, the girdle mesh 3503 comprises a compliant, lattice-like structure configured to cover at least a portion of the lower torso and upper leg region. In certain embodiments, the girdle flexible separation 3501 comprises a separation feature, seam, joint line, slit, or locally thinned region that provides controlled compliance and relative movement capability within the hip girdle 2101 as the torso and leg assemblies move relative to one another.

[0208] In certain embodiments, the hip girdle 2101, including the girdle mesh 3503, prevents intrusion into, and interference with, inner components disposed in the lower torso and upper leg regions. By spanning across openings and transitions between adjacent rigid or semi-rigid exterior components, the hip girdle 2101 reduces exposure of underlying mechanisms and wiring and limits access to pinch-prone internal regions during normal operation and incidental contact.

[0209] In certain embodiments, the hip girdle 2101 accommodates movement of the legs and bending of the torso without pinch points or interference developing. For example, during hipAttorney Docket No. ONEX-0008- WOflexion, hip abduction, and torso bending, the hip girdle 2101 is configured to stretch, compress, and / or locally deform, including through deformation of the girdle mesh 3503 and controlled motion at the girdle flexible separation 3501, thereby maintaining interference protection across a range of motion while allowing relative movement of adjacent body segments.

[0210] Referring to FIGS. 36-38, additional views of the hip girdle 2101 illustrate the girdle mesh 3503 as a three-dimensional mesh structure that extends around the hip region and includes a plurality of interconnected mesh segments. In certain embodiments, the mesh geometry provides directional compliance, including increased compliance in selected directions to accommodate leg swing and torso bending while maintaining sufficient stiffness to resist intrusion. In certain embodiments, the mesh geometry transitions across the hip girdle 2101 to provide varying compliance and structural support in different regions of the hip girdle 2101.In certain embodiments, the hip girdle mesh provides selected impact performance by distributing contact forces across the girdle mesh 3503 and by allowing controlled deformation under impact loading, thereby attenuating peak forces transmitted to underlying components and reducing contact severity for a nearby person. In certain embodiments, the hip girdle mesh provides selected heat transfer characteristics by defining openings and increased surface area that allow airflow through and around the hip region, thereby supporting convective heat rejection from internal components located in the lower torso region and reducing heat trapping beneath external coverings.

[0211] Accordingly, the hip girdle 2101, including the girdle mesh 3503 and the girdle flexible separation 3501, provides an exterior covering across a high-motion torso-to-leg transition region that maintains intrusion and interference protection, reduces pinch-point risk, accommodates leg and torso movement, and provides selected impact mitigation and heat transfer performance.

[0212] Referring to FIG. 22, a diagram illustrating knitted fabric structure details is shown, including four example fabric types for use with a humanoid robot. In certain embodiments, the four example fabric types include a base knit 2201, a horizontal mesh 2203, a horizontal ribbing 2205, and a vertical termination 2207. In certain embodiments, the fabric types are implemented in a unitary knit structure and / or as integrated knit zones within a garment, cover, or suit positioned over one or more impact shells and / or other exterior components of the humanoid robot.

[0213] In certain embodiments, the base knit 2201 provides a common exterior look for significant areas of the humanoid robot and provides baseline performance for wear, impact mitigation, and heat transfer capability. For example, the base knit 2201 may be used over torso, limb, and other broad surface regions to provide a consistent aesthetic finish, abrasion resistance, and a baseline level of compliance and cushioning when disposed over underlying shells or padding. In certainAttorney Docket No. ONEX-0008- WOembodiments, the base knit 2201 further provides baseline airflow and moisture transport to reduce heat trapping beneath exterior coverings.

[0214] In certain embodiments, the horizontal mesh 2203 provides improved heat transfer performance for selected areas of the humanoid robot. For example, the horizontal mesh 2203 may define a more open knit geometry relative to the base knit 2201 to increase airflow and convective heat rejection at selected regions, including regions adjacent to internal components that generate heat and / or regions selected for ventilation such as a back region, shoulder region, or other convective heat rejection position. In certain embodiments, the horizontal mesh 2203 is positioned to maintain exterior coverage while increasing permeability for air exchange.

[0215] In certain embodiments, the horizontal ribbing 2205 provides additional shaping for selected areas of the humanoid robot. For example, the horizontal ribbing 2205 may provide localized elasticity, contouring, and recovery to conform to underlying impact shells and to accommodate changes in cross-sectional geometry along the robot body, including around joints and transition regions. In certain embodiments, the horizontal ribbing 2205 provides a shaping knit that supports a tailored fit and controlled drape while maintaining flexibility for motion.

[0216] In certain embodiments, the vertical termination 2207 provides additional strength for selected areas of the humanoid robot. For example, the vertical termination 2207 may be used at terminating regions of garment portions and / or cover portions, including at a wrist region and / or an ankle region, to resist fraying, stretching, or creep under repeated donning and doffing and under cyclic motion. In certain embodiments, the vertical termination 2207 is additionally or alternatively used at high stress areas such as in a torso region where attachment and securing forces may be significant, including along seams, closure regions, and / or interfaces with fasteners or coupling features, thereby providing a reinforced termination structure configured to maintain alignment and retention of the fabric on the humanoid robot during operation.

[0217] Referring to FIG. 23, a diagram illustrating an example knit arrangement for a humanoid robot is shown. In certain embodiments, FIG. 23 depicts a knitted fabric cover and / or suit configured to be positioned over one or more impact shells of the humanoid robot to provide a continuous exterior surface while accommodating joint articulation. In certain embodiments, the knit arrangement comprises a plurality of knit zones distributed across a torso region, arm regions, and leg regions of the humanoid robot, with the knit zones selected to provide region-specific performance characteristics.

[0218] In the example shown, the knit arrangement includes a base knit 2201, a horizontal mesh 2203, a horizontal ribbing 2205, and a vertical termination 2207. In certain embodiments, the base knit 2201 is distributed over significant areas of the humanoid robot to provide a common exteriorAttorney Docket No. ONEX-0008- WOlook and baseline performance characteristics, including wear resistance, baseline impact mitigation, and baseline heat transfer capability. In certain embodiments, the horizontal mesh 2203 is positioned at selected areas of the humanoid robot to provide improved heat transfer performance, including increased airflow and convective heat rejection in regions selected for ventilation. In certain embodiments, the horizontal ribbing 2205 is positioned at selected areas to provide additional shaping, including localized elasticity and contouring to conform to underlying exterior components and accommodate changes in body geometry. In certain embodiments, the vertical termination 2207 is positioned at selected areas to provide additional strength, including at terminating regions and / or at higher stress regions that experience attachment and securing forces.

[0219] FIG. 23 further includes a legend indicating example texture patterns and corresponding example fabric appearances. In the example shown, the legend includes pattern markers 2301 and real world examples 2305, and provides example swatches corresponding to the base knit fabric 2307, the horizontal mesh fabric 2309, the horizontal ribbing fabric 2311, and the vertical termination fabric 2313. In certain embodiments, the legend is consistent with the example of FIG.22 and provides a reference for identifying knit-zone selection and placement across the humanoid robot.

[0220] Referring to FIGS. 24-31, example knit arrangements for a humanoid robot are shown. In certain embodiments, FIGS. 24-31 depict example fabric designs and layouts for a knitted fabric cover and / or suit configured to be positioned over one or more impact shells of the humanoid robot to provide a continuous exterior surface while accommodating joint articulation. In certain embodiments, the knit arrangements include a plurality of knit zones distributed across a torso region, arm regions, and leg regions of the humanoid robot, with knit-zone selection and placement configured to provide region-specific performance characteristics.

[0221] In certain embodiments, the fabric notations depicted in FIGS. 24-31 are consistent with those depicted in FIGS. 22-23, including notations corresponding to a base knit, a horizontal mesh, a horizontal ribbing, and a vertical termination. In certain embodiments, base knit regions provide a common exterior look for significant areas of the humanoid robot and provide baseline performance characteristics including wear resistance, baseline impact mitigation, and baseline heat transfer capability. In certain embodiments, horizontal mesh regions are positioned at selected areas to provide improved heat transfer performance, including increased airflow and convective heat rejection in regions selected for ventilation. In certain embodiments, horizontal ribbing regions are positioned at selected areas to provide additional shaping, including localized elasticity, contouring, and recovery to conform to underlying exterior components and to accommodate changes in body geometry. In certain embodiments, vertical termination regions are positioned at selected areas toAttorney Docket No. ONEX-0008- WOprovide additional strength, including at terminating regions such as at a wrist region and / or an ankle region and / or at higher stress regions that experience attachment and securing forces.

[0222] Referring to FIGS. 24 and 25, example fabric patterns are shown for a humanoid robot in which the knit zones are distributed across the torso and limbs in a manner configured to provide a selected balance of durability, flexibility, and ventilation. In certain embodiments, the distribution includes shaping and / or reinforcement at transition regions between the torso and limb regions and at joint-adjacent regions.

[0223] Referring to FIGS. 26 and 28, example suit patterns are shown including knit zones positioned to accommodate range of motion of the arms and legs while maintaining a selected exterior contour. In certain embodiments, the knit zones provide localized compliance and recovery to reduce wrinkling and bunching during movement.

[0224] Referring to FIGS. 27, 29, and 30, example fabric design layouts are shown illustrating knit-zone placement and continuity around the torso and limb regions. In certain embodiments, the layouts illustrate region-to-region transitions between knit zones to provide gradual changes in elasticity, permeability, and reinforcement across the suit.

[0225] Referring to FIG. 31, a side view of an example humanoid robot design is shown with knit zones arranged along the torso and limbs. In certain embodiments, the side view illustrates how knitzone placement is configured to accommodate bending at joints and changes in body cross-section while maintaining a consistent exterior appearance.

[0226] The example knit arrangements depicted in Figs. 23-31 are non-limiting and are provided to illustrate aspects of the present disclosure. The example arrangements provide for enhanced heat rejection in typical areas of interest, such as the upper torso, shoulders, back, and / or upper back, as well as provided enhanced flexibility in high motion regions. A given embodiment may vary these arrangements as desired, and / or according to the range of motion, duty cycle of movement, heat rejection plan, or the like of a particular humanoid robot according to the present disclosure.

[0227] Referencing Table 1, a non-limiting list of a number of joints present in example embodiments, and movement parameters, is depicted. Degrees of Freedom (DOF) are described in degrees of rotation for a related actuator for the respective joint. It will be noted that joints do not necessarily rest at a center point in the available range of rotation, i.e., joints may rotate more in one direction than another from a “rest” or “neutral” position. The Degrees of Freedom are described in Cartesian coordinates (e.g., using orthogonal X, Y, and Z planes) although any coordinate system may be selected, with appropriate transformations to the various parameters, and which do not affect the actual hardware configuration of the robot. The Range of Motion is described in degrees of movement, for example 60 degrees of total movement, and may include further descriptions forAttorney Docket No. ONEX-0008- WOexample rest points (e.g., resting at 20 degrees in the example would indicate that total rotation available is -20 degrees to +40 degrees). The presented joints include a range of motion and degrees of freedom that allow the robot to move in a similar manner to humans, including static movements and postures, as well as dynamic movements and intermediate positions, including movements used for traversing obstacles, interrupted actions, recovering balance, and / or changing intended actions in the middle of movements.Table 1. Example major joints, degrees of freedom for movement, and movement rangeAttorney Docket No. ONEX-0008- WO

[0228] In the example, the fingers may be embodied in any selected format. An example finger arrangement includes a finger pull at the end of the finger, where the intermediate joints naturally articulate as a part of the movement. Additionally or alternatively, more finger joints, or all finger joints, may include individually activated movement for each joint. In certain embodiments, the fingers are biased to a rest position (e.g., extended or nearly extended) and actuated toward a closing position. In certain embodiments, the fingers are actuated in both directions. The arrangement and actuating logic of the fingers may be varied according to the finger.Attorney Docket No. ONEX-0008- WO

[0229] In certain embodiments, one or more major joints, or all of the major joints, may be actuated in both directions, allowing for controlled movement in both directions. In certain embodiments, one or more joints may be biased to a position, and actuated away from that position. In certain embodiments, torque available for actuation of the joints may be anisotropic, for example with a different actuating torque and / or leverage profile in each direction, or isotropic, for example with the same actuating torque and leverage in each direction. In certain embodiments, one or more major joints may be velocity limited, either through inherent or enforced limitations on speed control (e.g., of a motor) and / or in the inherent hardware design (e.g., a given motor torque and leveraging profile allows for a determined speed and / or acceleration profile of the joint throughout the range of movement). In certain embodiments, main control of the joints is performed through torque control (or force control), allowing for a more predictable and human like response for movement and activity of the robot.

[0230] In certain embodiments, the foot includes a mid-joint, for example where the toes would bend over on a human foot. The example mid-joint, where present, may be articulating and may be biased to a neutral position (e.g., to allow natural walking movement and assist in energy recovery), the joint may be articulated, or both (e.g., allowing for conformation changes of the foot combined with walking energy recovery).

[0231] In certain embodiments, one or more, or all, major joints are powered utilizing tendon drives powered utilizing a rope tendon, coupled to articulate each joint in one or both directions according to the selected design. The tendon routing, inclusion of pulleys, direct inclusion of gears, and / or rope diameter may be utilized to adjust the final torque and gearing of each joint, allowing the joint to provide the selected force profile and movement range. The utilization of rope tendons allows for locating of motors to provide the selected weight distribution, is well suited for force / torque control, and provides similar dynamic response to a human as well as predictable motion in a human environment. Each joint may be driven in a single direction by a coupled motor, for example returning using a biasing force such as a spring. Each joint may be driven bidirectionally using two motors, using a reversible motor, and / or using a motor with a switching clutch or gear for reversal.

[0232] In certain embodiments, the knee joint utilizes two cooperating joints closely spaced together (e.g., 3-4 inches, or 75-100 mm apart) that better emulates the movement and range of a human knee compared to a single joint. In certain embodiments, the joint movements are fixed relative to each other, for example when the upper joint is at 60% extension, the lower joint is at a fixed extension (which may also be 60%, for example where the fixed relationship is also linear). In certain embodiments, the joint movements may be related in a correspondence, which may not beAttorney Docket No. ONEX-0008- WOlinear. In certain embodiments, the knee joints may have partial or complete independence of movement therebetween.

[0233] In certain embodiments, the positioning of motors, batteries, and other weight contributing components of the robot (e.g., pulleys, gears, brackets, tendon guides, etc.) are distributed to provide a similar center of mass for the robot to a human being, providing a similar physical experience for the robot as for a human being, including forces that would be experienced by the robot doing similar things a human would do (e.g., climbing stairs or ladders, minor impact response, etc.). In certain embodiments, the robot is configured to keep the weight of the robot directed between support points (e.g., the feet) when the robot is in a resting position or at positions near the rest position. In certain embodiments, one or more joints includes a brake that locks the joint at least selectively, for example when power is lost for the robot. In certain embodiments, the joints are powered and otherwise free moving (e.g., but may be limited in movement rate, for example where movement requires freewheeling a motor, which may slow or stop the movement), and the robot is configured to collapse into a squatting position in a shutdown or safe mode (e.g., rather than falling over).

[0234] Referring to FIG. 32, an external view of a humanoid robot 3200 is shown. In the example shown, the humanoid robot 3200 includes a head 3201, a torso assembly, a left arm assembly and a right arm assembly, a left leg assembly and a right leg assembly, and a foot assembly. In certain embodiments, the humanoid robot 3200 comprises a humanoid form factor configured for operation in human environments, including configurations in which external coverings such as fabric and / or suit layers are provided to present a human-like exterior appearance.

[0235] Example embodiments herein maintain low kinetic energy throughout the system, without limitation by minimizing both rotational inertia in the transmission and translational inertia at the limb level. In certain embodiments, the heaviest motion components (e.g., motors) are positioned close to the upstream joint, while transmission components are designed with minimal rotational inertia and only the necessary stiffness. These design strategies not only enhance intrinsic safety characteristics but also improve the system’s dynamic responsiveness, thereby supporting more precise and effective control performance. The utilization of tendon drives to provide power coupling and manage gear ratios provides a superior weight distribution compared to previously known transmissions such as planet gear systems. In certain embodiments, for example where other aspects of the present disclosure besides kinetic energy management are primary goals, and / or for movement control of one or more joints that may not have kinetic energy management as a primary goal, other power coupling and / or transmission systems may be utilized such as a planetary gear system.

In certain embodiments, the motor assemblies 3207, 3209, and 3211 are implemented as motor pairs, which may control movements individually and / or utilized to support differential drive actuation for multiple degrees of freedom.

[0238] In the example shown, the torso assembly includes a scapula motor 3213 and a spine motor assembly 3215. In certain embodiments, the scapula motor 3213 is configured to actuate a shoulder-related movement and / or internal rotation movement associated with the shoulder region of an arm assembly. In certain embodiments, the spine motor assembly 3215 is configured to actuate one or more spine joint movements coupling a pelvic sub-assembly to a remainder of the torso assembly, including flexion and / or rotation movements in selected implementations.

[0239] In the example shown, the pelvic region includes a hip motor assembly 3217. In certain embodiments, the hip motor assembly 3217 is configured to actuate one or more hip joint movements coupling a leg assembly to the torso assembly, including flexion and / or abduction movements in selected implementations. In the example shown, each leg assembly includes a knee motor 3219 and an ankle motor assembly 3221.

[0241] The arrangement of Fig. 32 is a schematic and non-limiting example. One or more motors of the humanoid robot may be utilized to operate a tendon drive for certain movements. TheAttorney Docket No. ONEX-0008- WOutilization of a tendon drive allows for displacement of the motors from the controlled joint, allowing for the flexibility to move motors around the robot as needed for weight distribution, thermal management, routing of wiring, or the like. Accordingly, the motor placements of Fig. 32, including which major sections of the robot where motors are positioned, are just a non-limiting example - for example the hip motor assembly may be positioned on the upper leg assembly and / or in the lower torso assembly, or elsewhere on the robot. The utilization of tendon drives also allows for convenient configuration of drive ratios (gear ratios) of the robot, from direct drive (e.g., the turning of the motor turns the final driven rotor that moves the selected joint either directly, or in a roughly 1 : 1 ratio), to a selected ratio (e.g., a rotor diameter ratio between a rotor moved by the motor and a final driven motor), and / or including one or more intermediate rotors to further adjust the total gear ratio.

[0247] Referring to FIG. 34, a hand schematic 3400 is shown. In certain embodiments, the hand schematic 3400 represents a hand of a humanoid robot configured to perform grasping and manipulation actions in human environments.

[0249] In certain embodiments, the hand wearing the glove is integrated into an actuator system in which the tactile sensor provides feedback for controlling manipulation, including controlling grip force and contact behavior. In certain embodiments, the tactile sensor outputs are provided to a controller and utilized to adjust one or more actuators associated with the hand to support stable grasping and safe interaction with objects and nearby humans.

[0250] Referring to FIG. 39, a diagram illustrating a hexagonal pattern torso shell design including a torso mesh 3901 is shown. In certain embodiments, the torso mesh 3901 comprises an impact shell and / or a shell component configured to at least partially define an outer shape of a torso assembly of a humanoid robot.

[0251] In the example shown, the torso mesh 3901 includes a tiled geometric pattern comprising a plurality of hexagonal openings and / or hexagonal wall segments arranged across a surface of the torso mesh 3901. In certain embodiments, the hexagonal pattern defines a lattice-like structure configured to defomr under impact loading to provide selected impact deformation characteristics and to recover toward an undeformed configuration after an impact event. In certain embodiments, the hexagonal pattern provides controlled compliance by distributing contact forces across adjacent hexagonal cells and enabling localized deflection of one or more cells in response to contact.

[0253] In certain embodiments, the hexagonal openings of the torso mesh 3901 provide selected heat transfer characteristics by allowing airflow through the openings and by increasing exposed surface area, thereby supporting convective heat rejection from internal components located in the torso region and reducing heat trapping beneath exterior coverings. In certain embodiments, a fabric cover and / or suit may be disposed over the torso mesh 3901 while maintaining airflow through the hexagonal pattern, including through a ventilation fabric or knit structure configured to permit air exchange.

[0254] Referring to FIG. 40, a set of depictions of shell components is shown, including a foam cover 4001 and a mesh cover 4003. In certain embodiments, FIG. 40 is provided to illustrate example outer covering approaches for a humanoid robot, and to compare a mesh shell of the present disclosure to a previously known foam shell.Attorney Docket No. ONEX-0008- WO

[0255] In the example shown, the foam cover 4001 comprises a foam shell that may be implemented as an open-cell foam and / or a closed-cell foam. In certain embodiments, the foam cover 4001 provides impact cushioning through compressive deformation of the foam material. However, in certain embodiments, foam-based coverings may exhibit variability in deformation and recovery behavior due to local material nonuniformity, aging, and / or differences in cell structure, and may provide limited configurability of region-specific deformation response relative to a structured shell geometry.

[0256] In the example shown, the mesh cover 4003 comprises a lattice-like shell structure configured to provide passive impact mitigation while protecting underlying components from intrusion and contact. In certain embodiments, the mesh cover 4003 comprises a patterned mesh including a plurality of openings defined by wall segments, such that contact loading produces controlled deformation of the wall segments and recovery toward an undeformed configuration after an impact event. In certain embodiments, the selected pattern and consequent performance can be readily designed into the lattice, and is repeatable at scale to provide consistent performance between humanoid robots.

[0257] In certain embodiments, the mesh cover 4003 provides a more consistent and configurable deformation and recovery response to impacts as compared to the foam cover 4001, for example by selecting one or more geometric parameters of the mesh cover 4003 including cell size, wall thickness, wall height, wall width, edge geometry, and / or pattern density to tune deformation response for a selected body region. In certain embodiments, the mesh cover 4003 provides controlled compliance by distributing contact forces across adjacent cells and enabling localized deflection under impact loading, thereby attenuating peak contact forces while maintaining structural protection.

[0258] In certain embodiments, the mesh cover 4003 further provides improved heat transfer relative to the foam cover 4001 by allowing airflow through openings of the mesh structure and by increasing exposed surface area, thereby supporting convective heat rejection from internal components and reducing heat trapping beneath external coverings. Accordingly, FIG. 40 illustrates example covering components in which a mesh shell provides engineered impact compliance and recovery and improved thermal performance as compared to a foam shell.

[0259] Referring to FIG. 41, a set of depictions is shown including a mesh front 4101 and a mesh rear 4103 of a mesh cover. In certain embodiments, the mesh cover comprises a lattice-like shell structure configured to provide passive impact mitigation while protecting underlying components of a humanoid robot from intrusion and contact, and to at least partially define an outer shape of a corresponding robot body region.Attorney Docket No. ONEX-0008- WO

[0260] In certain embodiments, the mesh front 4101 provides an outward-facing exterior surface of the mesh cover, including a patterned mesh geometry selected to provide a desired exterior appearance and selected deformation characteristics under impact loading. In certain embodiments, the mesh rear 4103 provides an inward-facing surface configured to interface with the underlying robot body and to support mounting of the mesh cover to the robot.

[0261] In the example shown, the mesh rear 4103 includes an engagement slot 4105.

[0262] Referring to FIG. 42, a set of depictions is shown including a foam rear 4201 and a mesh rear 4203 of corresponding shell components. In certain embodiments, FIG. 42 is provided to illustrate interior-side features of a foam shell and a mesh shell, where the interior side faces the robot body when installed.

[0263] In the example shown, the foam rear 4201 comprises an inward-facing surface of a foam cover. In certain embodiments, foam-based coverings may provide limited ability to repeatedly form and maintain detailed interior-side interface features due to local material nonuniformity, compressibility, and / or variability in deformation and recovery, which can complicate consistent accommodation of robot-side protrusions, mounting points, and other interior-side features.

[0264] In the example shown, the mesh rear 4203 comprises an inward-facing surface of a mesh cover. In certain embodiments, the mesh cover comprises a lattice-like shell structure configured to provide passive impact mitigation while protecting underlying components of a humanoid robot from intrusion and contact. In certain embodiments, the mesh rear 4203 includes one or more interior-side interface features configured to engage corresponding robot-side features. For example, in certain embodiments, the mesh rear 4203 includes an engagement slot 4205 configured to be engaged with a protrusion on the robot body to secure the mesh cover in a mounted configuration.

[0265] In certain embodiments, the mesh shell provides a more convenient and consistent design to accommodate features on the interior side of the shell facing the robot by enabling repeatable formation of interface geometry, including slots, keyed features, alignment edges, and / or mountingAttorney Docket No. ONEX-0008- WOinterfaces, thereby improving ease of securing and removal and improving consistency of fit and alignment across robots and across repeated service cycles. In certain embodiments, the interior-side interface features enforce a selected orientation of the mesh cover relative to the robot body, thereby ensuring that a desired exterior look and desired performance characteristics, including regionspecific compliance and airflow, are achieved when the mesh cover is installed.

[0266] Referring to FIG. 43, a magnified image of material structure is shown, including a foam cover 4001 and a mesh cover 4003. In certain embodiments, FIG. 43 provides a magnified view of the internal matrix of the foam cover 4001 and the structural matrix of the mesh cover 4003 to illustrate differences in permeability and porosity between the two covering approaches.

[0267] In the example shown, the foam cover 4001 comprises a foam matrix that may include open cells and / or closed cells and that provides impact cushioning through compressive deformation of the foam material. In certain embodiments, permeability through the foam cover 4001 is limited by the foam matrix and by variability in cell interconnectivity, cell size, and local material density.

[0268] In the example shown, the mesh cover 4003 comprises a lattice-like matrix including a plurality of openings defined by wall segments. In certain embodiments, the lattice-like structure provides clearly enhanced permeability relative to the foam cover 4001 by providing defined open flow paths through the mesh cover 4003. In certain embodiments, the porosity of the mesh cover 4003 is configurable by selection of one or more geometric parameters of the lattice, including without limitation cell size, opening shape, wall thickness, wall height, and / or pattern density, thereby enabling a desired balance of airflow, heat transfer, and impact deformation characteristics for a selected body region of the humanoid robot.

[0269] Accordingly, FIG. 43 illustrates that the mesh cover 4003 provides enhanced permeability and configurable porosity relative to the foam cover 4001, thereby supporting improved convective heat transfer and repeatable performance in an exterior covering for a humanoid robot.

[0270] Referring to FIGS. 44-46, a neck area fabric configuration for a humanoid robot is shown. In certain embodiments, the neck area fabric configuration is implemented as a neck cover 4400 that is configured to surround at least a portion of a neck region adjacent a head-to-torso interface and to provide a finished exterior appearance while accommodating relative motion of a head assembly and a torso assembly.

[0271] In certain embodiments, the neck area fabric includes a vertical termination knit at one or more stress points of the neck region. The vertical termination knit provides additional strength and dimensional stability at the stress points, for example to resist fraying, stretching, and creep under repeated head motion and repeated donning and doffing. In certain embodiments, the verticalAttorney Docket No. ONEX-0008- WOtermination knit is positioned adjacent to closure features and / or along edges that experience cyclic loading.

[0272] Referring to FIG. 46, the neck cover 4400 includes a zipper 4603 configured to provide convenient access to internal components of the humanoid robot in the neck region. In certain embodiments, the zipper 4603 provides an access path for maintenance, inspection, and / or adjustment of components, while allowing the neck cover 4400 to be returned to a closed configuration during operation.

[0273] Referring also to FIG. 46, the neck cover 4400 includes a magnet clasp 4601 configured to secure the neck area fabric in a closed and aligned configuration. In certain embodiments, the magnet clasp 4601 is positioned to bridge and retain opposing portions of the neck cover 4400, thereby reducing reliance on the zipper 4603 for retention during use. In certain embodiments, the magnet clasp 4601 reduces cyclic stresses that would otherwise be transmitted to the zipper 4603 during repeated head motion and body motion, thereby reducing the likelihood that the zipper 4603 will open over time and improving durability of the neck area fabric configuration.

[0274] Referring to FIG. 47, a mechanical drawing illustrating mesh bending and compaction for a shoulder mesh is shown. In the example shown, FIG. 47 depicts a shoulder close up 4700 including a shoulder mesh 4701 disposed in a shoulder region adjacent an articulated shoulder joint of a humanoid robot. In certain embodiments, the shoulder mesh 4701 comprises a compliant mesh structure that is configured to provide exterior coverage across a high-motion shoulder region while accommodating relative motion between a torso assembly and an arm assembly.

[0275] In certain embodiments, during a movement of the shoulder, the shoulder mesh 4701 is configured to deform to accommodate joint articulation. For example, the shoulder mesh 4701 may bend to follow the relative rotation between adjacent body segments, including by stretching in a first region of the mesh and compacting in a second region of the mesh, thereby maintaining exterior continuity while allowing the arm assembly to move through a range of motion.

[0276] In certain embodiments, the shoulder mesh 4701 retains protection for the shoulder region during movement by maintaining coverage over underlying joint mechanisms and by spanning across gaps that could otherwise be exposed during articulation. In certain embodiments, the shoulder mesh 4701 prevents inadvertent access to pinch points by limiting access to joint-adjacent internal regions as the shoulder moves.

[0277] In certain embodiments, the shoulder mesh 4701 further reduces interference arising from external coverings and adjacent robot components during movement. For example, the shoulder mesh 4701 is configured to resist snagging or intrusion of a fabric layer and / or other robot components into a shoulder-joint clearance region, thereby reducing the likelihood of unintendedAttorney Docket No. ONEX-0008- WOcontact that could impede motion and / or introduce unmodeled external forces during actuation. Accordingly, FIG. 47 illustrates an example shoulder mesh region providing compliant exterior coverage that accommodates shoulder articulation while maintaining impact and interference protection.

In such embodiments, a tendon is routed about, and / or is terminated to, the intermediate rotor to transmit force from the motor axis to the driven rotor 4807. The intermediate rotor provides routing options and intermediate gear selections as desired, including enabling tendon routing around packaging constraints within the motor housing 4801 and enabling selection of a mechanical advantage between the motor axis and the driven rotor 4807.

[0280] In certain embodiments, the terminator 4803 is configured to secure an end of a tendon, including for example by clamping, pinning, bonding, or otherwise coupling the tendon to a terminating feature.

For example, in certain embodiments, a motor pair housed by the motor housing 5501 is configured to operate a tendon drive coupled to the driven rotor 5503, wherein common rotation of the motor pair operates a first neck movement axis and differential rotation of the motor pair operates a second neck movement axis, thereby providing compact multi-axis neck actuation using a differential drive arrangement. In the example of Fig. 55, the motor pair controls head nodding motion as well as head tilting motion, while the neck secondary motor 5505 control head rotation from side to side.

[0300] In the example shown, the neck motor assembly 5500 further includes a neck secondary motor 5505. In certain embodiments, the neck secondary motor 5505 is configured as a direct drive motor for neck rotation, including embodiments in which the neck secondary motor 5505 directly drives a rotation axis of the neck joint (e.g., a yaw axis) over a limited range of motion, thereby reducing routing complexity and providing direct rotational control for the neck. In certain embodiments, the movement of a joint utilizing a single motor can still be a geared motion, although in the example of Fig. 55 it is a direct drive motion.

[0301] FIG. 56 illustrates a cross-sectional view of a tactile sensor 100 in accordance with aspects described herein. In some examples, the sensor 100 includes a contact layer 102 and a sensing array (or layer) 104. The contact layer 102 is a deformable layer configured to interface the sensing array 104 with the environment. In one example, the contact layer 102 includes an internal surface 106 and an external surface 108. The internal surface 106 is the side of the contact layer 102 that contacts (or engages with) the sensing array 104. In some examples, the internal surface 106 is made of a mechanically -resilient, electrically-conductive material. For example, the internal surface 106 mayAttorney Docket No. ONEX-0008- WObe made from an elastomer mixed with a conductive powder. The internal surface 106 is molded in a structured manner, such that the area in contact with the sensing array 104 varies locally according to the forces applied. In some examples, the internal surface 106 is structured to have a plurality of pillars (or nubs) that contact the sensing array 104. The plurality of pillars may be shaped as cones, hemispheres, cylinders, prisms, or any other suitable geometric shape. In some examples, the each pillar of the plurality of pillars has the same shape (e.g., cone, cylinder, etc.). In other examples, two or more pillars of the plurality of pillars have different shapes. In some examples, the plurality of pillars are arranged in an array having a uniform distribution (or spacing). For example, the plurality of pillars may be arranged in a two dimensional array having rows and columns. FIG. 57 illustrates an example internal surface 106 having a uniform distribution of pillars. In the illustrated example, the internal surface 106 has a plurality of conical pillars that are arranged in a uniform 6x8 array / grid covering a 10x14mm rectangular area. It should be appreciated that the plurality of pillars may be arranged in a non-uniform manner depending on the application.

[0302] The external surface 108 is the side of the contact layer 102 that is exposed for contact with the environment. In some examples, the external surface 108 is made from the same material as the internal surface 106 (e.g., an elastomer mixed with a conductive powder). In such examples, the contact layer 102 is a single-material component. In other examples, the external surface 108 is made from a different material than the internal surface 106. For example, the external surface 108 may be made of an elastomer that provides electrical isolation between the environment and the internal surface 106. In some examples, the shape (or form) of the external surface 108 corresponds to the intended robotic application for the sensor 100. For example, if the sensor 100 is configured as a finger (or to be included in a finger), the external surface 108 may be shaped like a human fingertip. Likewise, if the sensor 100 is configured as a foot (or to be included in a foot), the external surface 108 may be shaped like a foot sole (e.g., curved or flat).

[0303] The sensing array 104 includes a matrix (or array) of individually-addressable sensing elements. The sensing elements may be organized into rows and columns to simplify addressing. In some examples, the sensing elements are disposed on a rigid or flexible substrate and have varying electrical properties that depend on the properties of the materials in contact with their surface (or the distance of the material’s surface to them). For example, the capacitance, resistance, and / or other electrical properties of each sensing element vary according to the physical characteristics of the materials in contact with them. In some examples, the sensing array 104 includes a dielectric layer for measuring capacitance. In one example, the sensing array 104 has a resolution in the range of 500 dots per inch (DPI), which equates to approximately 250,000 capacitors per square inch. In other examples, the sensing array 104 is configured with a different resolution (e.g., higher or lower). InAttorney Docket No. ONEX-0008- WOsome examples, the measurements collected by the sensing array 104 are represented as a two-dimensional matrix of physical values that are proportional to the amount of capacitance on each sensing element. The position of each physical value in the matrix reflects the physical position of the capacitance source on the sensing array 104. In some examples, the sensing array 104 includes processing circuitry to perform physical value readings from the individual sensing elements. The processing circuitry may convert the physical value readings into a digital form for further processing (e.g., an image). In some examples, the sensing array 104 outputs electrical signals that are processed by external processing circuitry to perform the physical value readings.

[0304] As described above, the sensing elements of the sensing array 104 have electrical properties (e.g., capacitance) that vary based on the materials in contact with them. Deformations of the contact layer 102 due to external forces affect the portion of the internal surface 106 in contact with the sensing array 104 (e.g., the pillars), causing the electrical properties of the sensing elements to vary based on the external forces. In some examples, the sensing array 104 captures unique images for each force profile applied to the sensor 100.

[0305] FIG. 58 A illustrates an example of the sensor 100 in a first (or neutral) state. In the illustrated example, the internal surface 106 includes a 1x7 array of uniformly-sized conical pillars. In the first state, a uniform force is applied to the external surface 108 of the contact layer 102. Sample image 302 represents the image captured by the sensing array 104 in the example first state. As shown, each conical pillar is projected on the image plane as a circle having a substantially similar diameter. In some examples, the diameter of each circle is proportional to the force applied to external surface 108. Alternately, if using triangular or trapezoidal prism pillars, the pillars would be projected on the image plane as vertical lines / rectangles.

[0306] FIG. 58B illustrates an example of the sensor 100 in a second state. In the second state, a non-uniform vertical force is applied to the external surface 108 of the contact layer 102. The external surface 108 deforms due to the non-uniform force, causing non-uniform deformities in the plurality of pillars of the internal surface 106. In some examples, the deformation of each pillar corresponds to the local forces applied to the pillar. Sample image 304 represents the image captured by the sensing array 104 in the example second state. The size of each circle reflects the local magnitude of the force applied. For example, the largest circles correspond to the pillars that experience the highest force magnitudes, whereas the smallest circles correspond to the pillars that experience the smallest force magnitudes.

[0307] FIG. 58C illustrates an example of the sensor 100 in a third state. In the third state, a uniform shear force is applied to the external surface 108 of the contact layer 102 along with a uniform vertical force. The external surface 108 deforms due to the uniform shear force, causingAttorney Docket No. ONEX-0008- WOuniform deformities in the plurality of pillars of the internal surface 106. Sample image 306 represents the image captured by the sensing array 104 in the example third state. As shown, each pillar is projected on the image plane as a teardrop which indicates the horizontal deformation.

[0308] FIG. 58D illustrates an example of the sensor 100 in a fourth state. In the fourth state, a uniform shear force is applied to the external surface 108 of the contact layer 102 along with a non-uniform vertical force. The external surface 108 deforms due to the uniform shear force and the non-uniform vertical force, causing non-uniform deformities in the plurality of pillars of the internal surface 106. Sample image 308 represents the image captured by the sensing array 104 in the example fourth state. As shown, each conical pillar is projected on the image plane as a teardrop having varying sizes. In some examples, the size of each teardrop reflects the local magnitude of the force applied due to the combination of the uniform shear force and the non-uniform vertical force. For example, the largest teardrops correspond to the pillars that experience the highest force magnitudes, whereas the smallest teardrops correspond to the pillars that experience the smallest force magnitudes.

[0309] In some examples, the resolution of the sensor 100 is defined by the number of sensing elements covering the area of the conductive material in contact with the sensing array 104. FIGS.59A-59F illustrate various examples of configurations for the sensor 100.

[0310] FIG. 59 A illustrates an example high resolution configuration 400 of the sensor 100. In the configuration 400, the sensing array 104 is configured as an 8x10 array of sensing elements.Likewise, the internal surface 106 of the contact layer 102 is configured with an 8x10 array of conical pillars. The configuration 400 achieves high-resolution by providing a one-to-one paring of sensing elements to pillars. As such, forces applied to a first area of the contact layer 102 (e.g., column 1, row A) may be distinguished from forces applied to a second area of the contact layer 102 (e.g., column 1, row B). In some examples, the sensor 100 is configured with a lower resolution. For example, FIG. 59B illustrates an example low resolution configuration 410 of the sensor 100. In the configuration 410, the sensing array 104 is configured as an 8x10 array of sensing elements and internal surface 106 of the contact layer 102 is configured with an 4x5 array of conical pillars. As such, the resolution of the sensor 100 is reduced. However, the sensor 100 can distinguish between forces applied to a first area of the contact layer 102 (e.g., column 1, row A) and forces applied to a second area of the contact layer 102 (e.g., column 3, row A).

[0311] Depending on the robotic application, it may be advantageous to configure the sensor as a mixed resolution sensor. FIG. 59C illustrates an example of a mixed resolution configuration 420 of the sensor 100. In the configuration 420, the internal surface 106 of the contact layer 102 is configured with a mixed set of conical pillars. As shown, the internal surface 106 includes an outerAttorney Docket No. ONEX-0008- WOlow resolution ring of conical pillars and an inner high resolution array of conical pillars. Such mixed resolution configurations may be advantageous for specific robotic applications. For example, the configuration 420 may be useful in applications where the external surface 108 of the sensor 100 is curved (e.g., a thumb). In such situations, the forces applied to the outer portions of the external surface 108 may be less relevant than the forces applied to the inner portion of the external surface 108.

[0312] FIG. 59D illustrates another example configuration 430. In the configuration 430, the internal surface 106 is configured with both conical pillars and triangular pillars. Different types of pillars may provide unique deformations that are better suited for different robotic interfaces (or portions of interfaces). For example, triangular pillars may be better suited for the flat portions of a robotic foot, whereas conical pillars may be better suited for arched portions of a robotic foot, or vice versa. FIG. 59E illustrates an example configuration 440 that includes an internal surface 106 having different pillar shapes along with mixed resolution regions. FIG. 59F illustrates another example configuration 450 that includes different pillar shapes along with mixed resolution regions. As shown, the internal surface 106 is configured with a extra-high resolution region that includes two pillars per sensing element (e.g., columns 3-8, rows C-F). Along with mixed pillar shapes and sizes, it should be appreciated that the internal surface 106 can be configured with pillars made of different materials.

[0313] As described above, the main output of the sensor 100 is the digital readout from the sensing array 104, which corresponds to an image of the internal surface 106 of the contact layer 102 as detected by the sensing array 104. In some examples, the image is passed through one or more image processing (or computer vision) steps to extract contact force information. The contact force information may be absolute or relative values. In some examples, the image processing steps are performed by one or more processing controllers. For example, the image processing steps may be performed by one or more controllers of a robotic system. In other examples, the image processing steps may be performed by one or more cloud computing systems. In some examples, the image is processed via an image feature extraction system. In some examples, the image feature extraction system uses a morphological image processing technique to extract components from the image. For each element of the structure expected on the image, the module outputs a set of features relevant for identifying the element (e.g., size, position, centroid, eccentricity, etc.). The set of features are then used to compute the local forces applied to the plurality of pillars based on calibration data (or images) with known magnitudes and angles.

[0314] In some examples, the image feature extraction system uses one or more machine learning (ML) or artificial intelligence (Al) models to extract image features. In some examples, a modelAttorney Docket No. ONEX-0008- WO(e.g., a neural network) is trained using calibration data to output local and / or global force measurements. The trained model is then used to compute local forces applied to the plurality of pillars and / or global forces applied to the sensor 100 based on the images generated by the sensing array 104. In some examples, the model is trained to provide an end-to-end robotic control approach. For example, the trained model can implicitly determine the force vectors applied to the sensor 100 and use them to compute actuator outputs for controlling the robotic system. In some examples, the trained model is configured to output the actuator control outputs without outputting numerical force measurements from the sensor 100. In some examples, an encoder-decoder network is utilize to compress data and communicate only relevant information between the sensor 100 and the processing controller (or computer). By training an autoencoder with an image (e.g., output by the sensing array 104), the encoder-decoder network can perform a compression into a latent space. The compressed data (or image) may exclude features that are expected by humans to process the image. However, the output of the encoder stage is communicated and understood by a different system (e.g., the processing controller). In some examples, the image feature extraction system is a hybrid system that utilizes a morphological image processing technique with a trained ML model (e.g., a neural network). In such examples, the morphological image processing technique is used to preprocess the image for the trained model. For example, the morphological image processing technique may be used to extract features from the image that are then analyzed by the trained model to compute the local and / or global forces.

[0315] FIG. 60 illustrates an example of a robotic system 500 that includes the sensor 100. As shown, the system 500 includes a robotic interface 502 that is coupled to the sensor 100. In some examples, the robotic interface 502 is a finger, hand, foot, or another surface of the robot. As such, the sensor 100 may be attached to (or included in) a fingertip, palm, toe, heel, or sole of the robot. The robotic interface 502 is configured to be actuated via one or more actuators 504. The actuators 504 are configured to receive controls from a controller 506. In some examples, the robotic interface 502 is operated (e.g., via the actuators 504) to contact an object 508. The actuated motion of the robotic interface 502 causes the sensor 100 to contact or engage with the object 508. As described above, the contact with the object 508 causes one or more forces to be applied to the contact layer 102 of the sensor 100. The applied force(s) are captured via image by the sensing array 104 of the sensor 100 and transmitted to the controller 506 for further processing. In some examples, the controller 506 is configured to operate as the image feature extraction system described above. As such, the controller 506 may compute the local and / or global forces applied to the sensor 100 and adjust the control of the actuators 504 as desired.Attorney Docket No. ONEX-0008- WO

[0316] FIG. 61 illustrates another example of a robotic system 600 that includes the sensor 100. As shown, the system 600 includes two robotic interfaces 602a, 602b that are coupled to sensors 100a, 100b. The first robotic interface 602a is configured to be operated by actuators 604a and the second robotic interface 602b is configured to be operated by actuators 604b. In some examples, both sets of actuators 604a, 604b receive controls from a controller 606. However, in other examples, the actuators 604a, 604b may receive controls from different controllers. In some examples, the robotic interfaces 602a, 602b are operated (e.g., via the actuators 604a, 604b) to contact an object 608. The actuated motions of the robotic interfaces 602a, 602b cause the sensors 100a, 100b to contact or engage with the object 608. The forces applied to each sensor 100a, 100b are captured by the corresponding sensing arrays and transmitted to the controller 606 for further processing. The controller 606 may compute the local and / or global forces applied to each sensor 100a, 100b and adjust the control of the actuators 604a, 604b as desired. In some examples, the sensors 100a, 100b are used to provide feedback for the control of the opposing robotic interface 602. For example, the first robotic interface 602a may correspond to the left hand of the robot and the second robotic interface 602b may correspond to the right hand of the robot. When being operated to pick up the object 608, the forces applied to the first sensor 100a (i.e., attached to the left hand) may be used to operate the actuators 604b that control the second robotic interface 602b (i.e., the right hand). If the forces applied to sensor 100a are insufficient to complete a task (i.e., picking up or holding the object 608), the controller 606 may control the actuators 604b such that the second robotic interface 602b (and the sensor 100b) press against the object 608 with additional force to increase the force experienced by the first robotic interface 602a (and the sensor 100a). Such feedback control loops using multiple sensors 100a, 100b may be advantageous for mitigating multi-dimensional forces (i.e., vertical and shear) in robotic applications.
