Design of A Prosthetic Hand for Multiple hand Motions.

In this paper, a prosthetic hand which has been considered both of multiple hand motions and lightweight was presented. By integrating different digits functions of stable linkage four fingers and adaptive thumb, the proposed hand is capable to realize 10 types of hand motions based on the frequently-used hand motions. Furthermore, the proposed hand is modeled based on an adult hand size, with three motors embedded in the palm. Finally, the experiment had been conducted to verify the motion function and grasp performance.
