This hand prostheses will be designed to do the activities of daily living of the amputees. In order to bring the fingers to pre-defined tasks 3 DC motors will be used. This prosthesis has 8 degrees of freedom and will be prototyped by 3D-printer using ABS material.

RoboWrist

Large portion of amputee population around the world are trans-humeral amputees. Requirement for a light weight and adjustable wrist joint to change the stiffness of it in various situations is essential. In this project a novel wrist joint which is either low weigh or active has been proposed. Using this wrist joint with an innovative mechanism design will enable amputees to control the stiffness of their joint based on the weight of the object that they want to hold or pick it up. The wrist design has been realized by printing it in the 3D printer with ABS material. Brushless DC motor have been used to actuate the wrist joint according to the applied forces.
