An exoskeleton having a mechanism for elastically balancing loads applied to the exoskeleton is provided. The mechanism has a rigid connection element and a rigid housing mutually pivoted to one another about a first axis of oscillation and attachable to respective relatively rotatable parts of the exoskeleton. A lever is rotatably mounted to the rigid housing about a second axis of oscillation. A flexible traction element has a first end rotationally secured to the rigid connection element with respect to the first axis of oscillation and a second end secured to the lever at a securing point spaced from the second axis of oscillation. A compression spring exerts a thrust, away from the first axis of oscillation, against a portion of the lever intermediately between the second axis of oscillation and the securing point to the second end of the flexible traction element.

Elastic balancing of loads in an exoskeleton

An artificial wrist including a static body adapted to be bound to a support; a movable body adapted to be bound to an end effector; and a junction block defining an axis of rotation between the static body and the movable body and including a cable suitable to be moved by mutual rotation of the bodies and around the axis of rotation, and elastic member placing the cable under tensile stress and working in opposition to the movement of the cable to define a rest position in which the cable and the elastic member exerts a zero resulting torque on the bodies and, and an activation position in which they exert a non-zero resulting torque on the bodies and, bringing the bodies and back to the rest position.

Artificial wrist

Underactuated prosthetic hand including base body; first and second prosthetic fingers each hinged to the base body; first control cable; actuator to move the first control cable; and for each pair of fingers second control cable having control ends associated with the first and second fingers; and transmission block to allow first control cable to control second control cable; transmission block includes guide integral with base body and defining sliding axis; movable element sliding along guide; first pulley for sliding first control cable hinged to movable element and second pulley for sliding second control cable hinged to the movable element so actuator, when moving first cable, determines moveable element translational movement to displace second control cable and the fingers; and elastic means opposing moveable element translational movement so the moveable element translational movement opposes elastic means allowing them to facilitate return to moveable element initial position.
