Elumotion Ltd. Actuated Sheffield Hand

Elumotion Ltd. manufactured a replica of the Sheffield Hand for Orebro University and subsequently devised an actuation strategy for 12 degrees of freedom of this hand.

Following from the findings of the development of the Sheffield Hand, the actuation components were designed in modules. Each module to power the flexion and extension of the finger comprises telescopic rods, complete with a series elastic element.

The rods pull on ‘tendons’ to the fingers, in a similar manner to how the real hand works. A second smaller module, based on a similar principle’, moves the fingers from side to side and is situated in the space of the hand.
Work on this hand is ongoing.
