Motion capture system is becoming one of the very important tools serving in the process of calculation, design process as well as evaluating the performance of the rehabilitation equipment. In addition, it is also common device used in the performance evaluation of rehabilitation process during exercise stages. In this article, a cheap motion capture system measured 7 Degree of Freedom (DOF) of upper limb will be presented. The system is designed similar to the skeleton structure with the adjustable size fit each arm anthropometry. The application of 3D printing technology serving the manufacturing process ensure that the system has created is characterized by lightweight, low cost. Some initial experiments assess the extent of the angle measured efficiency as well as some basic actions in daily activities.
