An artificial hand is provided. The artificial includes phalanges suitable to reproduce at least one finger, hinges hinging a first element identifying a phalanx to a second element identifying a second phalanx, and an implementation mechanism suitable to command a reciprocal rotation between the hinges defining a mutual rotation speed between the first and second element. The hinges define different damping coefficients so that, during a mutual rotation of the first and second element, they are subject to distinct damping forces opposing mutual rotation and proportional to the mutual rotation speed so as to vary the movement of the artificial hand as a function of the mutual rotation speed.

Artificial hand

Provided is a robotic hand which includes a palm, a plurality of phalanges adapted to reproduce a plurality of fingers, and an actuating mechanism. The actuating mechanism may include a first pulley located at each hinge and bound to the first element, second pulleys located at each of the hinges and bound to the second element, a single cable running in all of the pulleys and a motor adapted to act on the cable by controlling the rotation of the phalanges.
