Abstract

Abstract: In order to reduce the costs and expense during prosthetic hand research process, a simulation system of prosthetic hand was built by using the virtual technology. Building the multi-DOF prototype model of prosthetic hand with virtual modeling software Pro/E, the model was imported into software ADAMS to verifying the feasibility of prosthetic hand kinematic simulation. Through the interface modular part (ADAMS /control) of MATLAB and ADAMS, using Simulink module of MATLAB software built the prosthetic hand model control system of EMG (electromyography), changing the model information of the corresponding hand movements into actual expected angel of prosthetic hand joints. The signal, which was collected by the EMG signal acquisition system, was handled based on the threshold decision of the mean absolute value, then extracted time domain feature of EMG signal and sent it into MATLAB, beginning coordinated simulation. The research results show that the drive of EMG prosthetic hand is successfully implemented by simulation system of EMG prosthetic hand based on MATLAB and ADAMS. The feasibility of EMG prosthetic controlling scheme hand has been verified by using the real-time coordinated simulation.
