prehensile robotic element strap on from a subject for help to the grip

摘要

A device (100) for enhancing a user's (1) grasping capability comprises a belt- like support (102) configured to be tightly fitted about a user's (1 ) part of the body (3); at least one articulated gripping element (130) having a plurality of phalanxes: proximal (131), fixed to the support (102), intermediate (132) and distal (133), which are articulated to each other by articular joints (135); a motor unit (120) fixed to the support (102); a winding drum (125); at least one tendon (140) partially wound on the drum (125) and extending along the phalanxes (131,132,133) and the joints (135), arranged in such a way that, by pulling it from the drum (125), the phalanxes (131,132,133) rotate about respective articular joints (135) and move the articulated gripping element (130) from an extended position (A) to a gripping bow-shaped position (B), causing a flexion/extension movement of the articulated gripping element (130), the joints (135) configured in such a way that by releasing the tendon (140) from the drum (125), the phalanxes (131,132,133) rotate about the respective joints (135) and move the articulated gripping element (130) between gripping bow-shaped position (B) and extended position (A).
