An exoskeleton worn by a human user consisting of a rigid pelvic harness worn about the waist of the user and exoskeleton leg structures each of which extends downwardly alongside one of the human user's legs. The leg structures include hip, knee and ankle joints connected by adjustable length thigh and shin members. The hip joint that attaches the thigh structure to the pelvic harness includes a passive spring or an active actuator to assist in lifting the exoskeleton and said human user with respect to the ground surface upon which the user is walking and to propel the exoskeleton and human user forward. A controllable damper operatively arresting the movement of the knee joint at controllable times during the walking cycle, and spring located at the ankle and foot member stores and releases energy during walking.

A human-computer interface system having an exoskeleton including a plurality of structural members coupled to one another by at least one articulation configured to apply a force to a body segment of a user, the exoskeleton comprising a body-borne portion and a point-of-use portion; the body-borne portion configured to be operatively coupled to the point-of-use portion; and at least one locomotor module including at least one actuator configured to actuate the at least one articulation, the at least one actuator being in operative communication with the exoskeleton.

The present invention relates to an exoskeleton interface apparatus that parallels human arm motion and is comprised of a serial assemblage of five powered linkages and joints based at a rigid support structure worn on the torso of the human subject. Such apparatus generates shoulder rotation using three orthogonal revolute joints mounted on serial linkages encompassing and intersecting at the anatomical glenohumeral joint. Elevation of the shoulder joint is articulated using a link member driven by a single revolute joint mounted in the torso structure. Passive adjustable linkages are used to match variation in anatomical forearm length, upper arm length, and scapula-to-glenohumeral radius. A plurality of integrated dc motor/harmonic drive transmission modules is co-located on adjoining linkages to power the joints. Force is exchanged with the human at the handgrip and elbow brace, and reacted to the torso structure via the base attachment. The present invention is applicable in particular to rehabilitation of the shoulder.

An exoskeleton bracing system includes: a trunk support for affixing to the trunk of a disabled person and leg braces for connecting to the legs of the person, each leg brace including limb segment braces. Motorized joints are adapted to provide relative angular movement between the limb segment braces of the leg braces and between the leg braces and the trunk support. One or more ground force sensors are designed to sense ground force exerted on each of the leg braces. The system also includes a controller for receiving sensed signals from said one or more ground force sensors, with an algorithm for identifying a stance from the sensed signals and, based on the identified stance, actuating the motorized joints to perform an action relating to a mode of locomotion selected from a set of predefined actions corresponding to the identified stance.

The present invention relates to an apparatus for a Robust CMM Arm with Exoskeleton is provided comprising an Internal CMM Arm and an Exoskeleton driving the Internal CMM Arm through a plurality of transmission means such that one or more internal volumes are sealed against ingress of solid objects and fluids. It also relates to a haptic control of an RCA.

An exoskeleton configured to be coupled to a person includes an exoskeleton trunk and leg supports adapted to contact the ground. Hip torque generators extend between the exoskeleton trunk and respective leg supports. A load holding mechanism is rotatably coupled to the exoskeleton trunk, preferably via over-shoulder members configured to support a load in front of the person. In use, hip torque generators create torque between the exoskeleton trunk and respective leg supports in the stance phase, wherein at least one torque generator is configured to create a first torque between the exoskeleton trunk and one of the first and second leg supports in the stance phase opposing a second torque generated on the exoskeleton by a weight of the load. Load bearing sensors may be utilized to determine the torque generated by the load and communicate with a controller to control power to the torque generators.

This document discloses, among other things, a wearable structure having links and joints corresponding to those of a human upper body. Transducers are located on the wearable structure and are coupled to a processor. The transducers exchange energy and information between the user and the wearable structure and enable control of the movement of the structure.

A system and method for the repair of damaged tissue and bones, congenitally missing tissue/cosmetic reconstruction of tissue is described. The system has a layered porous structure with a sufficiently large area of exposed pores to promote neo-vascularization as well as bone and tissue formation. The disclosed porous implant system can contain bioactive agents necessary for rapid tissue formation and keep ingrowth of unwanted tissue out of the implant surgical site. The implant can be reinforced with an additional, stronger polymer layer and/or may include an endoskeleton or exoskeleton for dimensional stability.

A lower extremity exoskeleton, configurable to be coupled to a person, includes: leg supports configurable to be coupled to the person's lower limbs and designed to rest on the ground during stance phases, with each leg support having a thigh link and a shank link; two knee joints, each configured to allow flexion and extension between respective shank and thigh links; an exoskeleton trunk configurable to be coupled to the person's upper body, rotatably connectable to the thigh links of the leg supports, allowing for the flexion and extension between the leg supports and the exoskeleton trunk; two hip actuators configured to create torques between the exoskeleton trunk and the leg supports; and at least one power unit capable of providing power to the hip actuators. In use, power is supplied to the hip actuators in an amount to reduce the energy consumed by a user during a walking cycle.

The invention discloses a wearable lower limb exoskeleton walking-assisted robot, which comprises an ankle joint motion module, a knee joint motion module, a hip joint motion module, a drive module and a waist and supporting frame module, wherein the knee joint motion module is connected with the ankle joint motion module and the hip joint motion module respectively; the drive module is connected with the knee joint motion module and the ankle joint motion module respectively; and the hip joint motion module is connected with the waist and supporting frame module. During the walking period of the robot, the consistency of hip joint motion and human body motion is good, the coaxiality and the position deviation of the knee joints of a human body and the robot are small, and the ankle joint is compact in structure.

A multi-layered microcapsule has an inner extracellular matrix and an outer shell. The inner extracellular matrix includes a first inner layer of biopolymer and a second intermediate layer of polymer that provides partial immune-protection and holds the first layer in place. The outer shell can form an exoskeleton to provide mechanical stability. Each of the individual layers can be varied to optimize mechanical stability, cell function, and immuno-protection.

A control system for controlling an exoskeleton worn by a user and having one or more actuators associated with various body members of the exoskeleton each corresponding to a body part of the user. The control system comprises a user interface for receiving input data indicative of a desired movement sequence, a memory component for storing pre-programmed movement data indicative of one or more sequential instructions required to effect the movement sequence, each instruction being associated with relative actuator movements for performing the instruction, and an actuator controller for moving the one or more actuators according to the relative actuator movements for each instruction. The control system also comprises a terrain sub-system for adjusting the actuator movements upon detection of a change in terrain slope and a balance control sub-system for periodically adjusting the balance of the exoskeleton during relative movement of the one or more actuators.
