A grasping device for an object comprising a platform (10) with longitudinal axis (X) and six fingers (13, 14) articulated for rotation on the platform (10), and grasping means carried by each of the free ends of the fingers (13, 14), the at least three fingers (13, 14) being regularly articulated angularly around the longitudinal axis (X), each finger (13, 14) comprising a double parallelogram linkage including a first parallelogram (P1) articulated on the platform (10) about an axis orthogonal to the longitudinal axis (X), a second parallelogram (P2) being articulated on the first parallelogram (P1), and a set of gears between the first parallelogram (P1) and the second parallelogram (P2), such that the movement in one direction of rotation of the first parallelogram (P1) imposes a movement in the opposite direction of rotation of the second parallelogram. (P2),and an actuator (A1) carried by the platform and configured to move all the fingers (13, 14) simultaneously. [Fig.2]

To provide a durable and simply constructed work hand protection device that can safely protect the back and palm of the hand. [Solution] This work hand protection device has three sets of openings: a first finger opening for inserting the thumb, a second finger opening for inserting all fingers other than the thumb, and a wrist opening for inserting the wrist, and covers the back and palm sides of the worker's hand to protect the worker's hand. The device has a cushioning material built in and is a rectangular protective body of a predetermined length that is bent in a U shape from the back of the hand to the palm side via the knife part of the worker's hand. It consists of a first connecting member located on the wrist opening side of the protective body and detachably connecting the open ends of the protective body, and a second connecting member located on the second finger opening side of the protective body and elastically connecting the open ends of the protective body, with the opening between the first and second connecting members being the first finger opening for inserting the thumb.

The invention relates to a dental floss applicator 2 in the form of a closed loop 4 made from a section 7 of dental floss 6, which is connected to itself at its ends to form the loop 4. The closed loop design 4 allows the user to use the dental floss 6 more easily without having to wrap it around individual fingers. The user can tighten the loop 4 with several or all fingers and, for example, gently insert it into the interdental spaces with their index fingers or thumbs, easily placing a piece of unused dental floss 6 for each tooth.

The invention discloses a dexterous hand multi-mode perception and control method, system and device and a medium, and relates to the field of dexterous hand multi-mode perception and control, and the method comprises the steps: obtaining original tactile data and original visual data corresponding to each finger; performing data compression and semantic fusion on the original tactile data and the original visual data to obtain a fusion feature vector corresponding to each finger; inputting the fusion feature vector corresponding to each finger into a finger-level KAN subnet corresponding to the finger to obtain a motor torque suggestion value; inputting the intermediate layer features of the finger-level KAN subnet into a global collaborative KAN network, and predicting to obtain a torque correction coefficient set; the torque correction coefficient set comprises torque correction coefficients of all joints of all fingers; and the motor torque value and the torque correction coefficient of each joint of each finger are used for performing multi-finger cooperative control on the dexterous hand. According to the invention, high-precision and high-adaptability control of the dexterous hand is realized.

The invention discloses a negative pressure suction cup dexterous hand used for grabbing flexible materials and a grabbing method, the dexterous hand comprises a base and three fingers evenly distributed in the circumferential direction, each finger is formed by sequentially hinging a far finger end, a middle finger end and a near finger end, and each joint is driven by an independent motor to achieve pitching or swinging motion. The finger pulp of the far finger end is provided with an array type negative pressure suction cup, the finger back is provided with an independent air path connector, the suction cups of all the fingers are connected in parallel through air pipes and then connected to a shared negative pressure adjusting valve and a vacuum source, and unified adjustment of air pressure is achieved. The suction cup can be attached to a complex curved surface in a self-adaptive mode by independently controlling all fingers and all knuckles to move; the negative pressure of the suction cups is adjusted on the basis of the material of the cloth, and efficient and lossless separation of single layers in the stacked cloth can be achieved; and after separation, the fingers can be cooperatively folded to form wrapping type stable grasping of the cloth. The problems that the flexible thin-layer material is difficult to separate and unstable to grab in the automatic grabbing process are solved.

The application discloses a dexterous hand multi-modal perception and control method, system, device and medium, relates to the field of dexterous hand multi-modal perception and control, and comprises the following steps: acquiring original tactile data and original visual data corresponding to each finger; performing data compression and semantic fusion on the original tactile data and the original visual data to obtain a fusion feature vector corresponding to each finger; inputting the fusion feature vector corresponding to each finger into a finger-level KAN subnet corresponding to the finger to obtain a motor torque suggestion value; inputting an intermediate layer feature of the finger-level KAN subnet into a global collaborative KAN network to obtain a torque correction coefficient set; the torque correction coefficient set comprises torque correction coefficients of all joints of the fingers; and the motor torque value of each joint of each finger and the torque correction coefficient are used for multi-finger collaborative control of the dexterous hand, so that high-precision and high-adaptability control of the dexterous hand is realized.

This utility model relates to the field of finger machining technology, and more particularly to a tooling for drilling holes in parts, aiming to solve the problem of low efficiency in clamping and removing fingers in existing drilling tooling. This utility model includes a base plate, side limiting plates, and a pressure plate; the base plate is used to contact the bottom surface of the finger; the side limiting plates have multiple side limiting holes for contacting the sides of the finger, into which the finger is inserted; the pressure plate is used to contact the top surface of the finger; the base plate, side limiting plates, and pressure plate are detachably connected, and the side limiting plates are configured to move towards the base plate to disengage the finger from the side limiting holes. When clamping the finger, simply connecting the base plate, side limiting plates, and pressure plate is sufficient to fix all fingers, eliminating the need to fix each finger individually, greatly reducing the clamping workload. During disassembly, simply removing the pressure plate and moving the side limiting plates downwards allows the finger to disengage from the side limiting holes, eliminating the need to remove each finger individually, greatly improving removal efficiency.
