Abstract
In this study, the prosthetic hand that combines the advantages of a cosmetic prosthetic hand and a functional prosthetic hand is designed and its prototypes are produced. The clearance in every joint of a finger like that in a machine is also focused on for achievement of the natural and soft movements of human being original. Several 3-dimensional CAD models of the prosthetic hand with reference to the human hand were made and the prototypes of them were produced using the 3-axis NC machine tool actually. The results of the operation tests by the manual manner show that the prosthetic hand developed in this study can pick a piece of paper on the table and grip a cylinder.
