The paper proposed a locomotion simulation method of the lower limb EMG-prosthesis based on OpenGL. Firstly, the raw surface EMG and real knee angle are stored, and the features of surface EMG are extracted after preprocessed and transformed with Wavelet Packet. Secondly, the model of EMG is built with Support Vector Machine, and the knee angles of prosthesis are forecasted during the whole gait cycle. Finally, the lower limb model is built and locomotion locus of prosthesis is confirmed based on OpenGL. So the control result can be seen easily according to locomotion simulation of the prosthesis model on the computer. This paper indicates that the method and theory are feasible.
