Dexterous gripper for robotic end-effector applications
A robot gripper includes two fingers of a grasper assembly configured to perform grasping motions via actuation of independent cable ends of a plurality of cables, and configured to move toward or away from each other to perform the grasping motion. Wherein each gripper finger is actuated by a pair of cables, a cable of the pair slides in a flexible sheath when actuated by a motor, moving the gripper finger in an opposite direction of another cable of the pair also in a flexible sheath, providing equal motions of each cable in the pair in opposite directions. A motor assembly including the motors is mounted at a location separate from the grasper assembly with the flexible sheathing extending between the assemblies. Such that the separate assembly mounting arrangement provides an improved ratio between a gripping force of the grippers versus the robot-lifted mass of the grasper assembly.
Robot appendage
A robot hand including a set of carpal bones, each of the carpal bones having at least one adjacent bone; and each carpal bone defining at least one socket. For each pair of adjacent carpal bones, at least one connector having a first and second end and wherein the first end and the second end are each in the form of a ball, and wherein the balls are joined by a connective element. Wherein the ball at the first end of the connector is fitted conformally into the socket of a first one of the pair of adjacent carpal bones and the ball at the second end of the connector is fitted conformally into the socket of a second one of the pair of adjacent bones, thereby joining the carpal bones together, but permitting limited relative movement.
Compliant Gripper
Grippers, such as robotic grippers, and associated methods and systems are disclosed herein. One disclosed gripper includes a first compliant gripper jaw, a first push-pull assembly having a first distal end fixed on the first compliant gripper jaw, a second compliant gripper jaw, a second push-pull assembly having a second distal end fixed on the second compliant gripper jaw, and an actuator connected to both the first push-pull assembly and the second push-pull assembly.
A DEVICE FOR ENHANCING A SUBJECT'S GRASPING CAPABILITY
A device for enhancing a user's grasping capability comprises a belt-like support configured to be tightly fitted about a user's part of the body; an articulated gripping element having a plurality of phalanxes: proximal, fixed to the support, intermediate and distal, which are articulated to each other by articular joints; a motor unit fixed to the support; a winding drum; a tendon partially wound on the drum and extending along the phalanxes and the joints, arranged so that, by pulling it from the drum, the phalanxes rotate about respective articular joints and move the articulated gripping element from an extended position to a gripping bow-shaped position, causing a flexion/extension movement of the articulated gripping element, the joints configured so that by releasing the tendon from the drum, the phalanxes rotate about the respective joints and move the articulated gripping element between gripping bow-shaped position and extended position.
