Abstract

This project illustrated a rapid prototyping prosthetic hand that have been modified from two joint of fingers to become three joints with the purpose to increase its flexibility. With the use of Solidwork software, the prosthetic hand is modified and designed. A modular, low-cost and light-weight prosthetic hand in this project is built and printed by using 3D printing technology. Originally the prototype was being operated by using strain pressure sensor from skin. However, in order to increase its efficiency, the prosthetic hand of this project is being replaced by electromyography signal captured from forearm muscle rather than using pressure sensor. The method used to process the electromyography signal is root mean square and there is only two gestures been classified in this project. Therefore, a threshold value have been calculated from the summation of RMS by measuring the value when opening and closing the hand, then divide by two. This method has a rapid and precise response on controlling the movement of the prosthetic hand. The hand is the very important to us especially in daily activity. Therefore, this project is aimed to be affordable to all level of consumers and can be applicable to limbs amputees as well.
