A low cost anthropomorphic prosthetic hand using DC micro metal gear motor

This research focus on developing of low cost anthropomorphic prosthetic hand using DC micro metal gear motor. The DC metal gear motor is selected as actuator because it is easy to find, low cost, and light weight. The prosthetic hand is based on 3D printed material that enables it light weight, low cost, easy to manufacture and easy to maintain. The mechanism of the hand is based on the tendon spring mechanism. The prosthetic hand has five degree of freedom (DOF) and two joints in each finger. For performing the activities of daily living (ADLs), the hand is designed with seven grip patterns. Based on the experimental results in grasping test and writing test on the white board, the hand can be used as low cost prosthetic hand replacing the passive prosthetic hand that has been available on the market.
