| Summary: | 碩士 === 國立臺北科技大學 === 機電整合研究所 === 94 === This thesis presents a new mechanism design for Non-myoelectrical controlled prosthesis-hand, which could provide upper-limb handicapped better controllability and independence.The scope of this study mainly includes：(1) Improve the opening motions of prosthesis fingers to closely simulate those of a normal person; (2) Provide the rotating motion of wrist to make the prosthesis palm be able to grasp objects on different planes.
This new prosthesis-hand has been developed in accordance with the motions of fingers and wrist of a normal person, and by applying the method of creative mechanism design. The design mainly uses linkages in its mechanism to achieve the goal of using three fingers in different motion planes to grasp object in order to increase the grasping stability. In addition, this new prosthesis-hand could perform the rotating motion of wrist after grasping object in order to increase its applicability.
The kinematic analysis and mechanical advantage analysis have been performed on those potential mechanisms obtained by the method of creative mechanism design. The optimum design and simulation have been conducted by ADAMS software to select the final design and prove its feasibility as well. The prototype has been made, tested and modified. Therefore, the feasibility of this new prosthesis-hand has been confirmed.
