Wheelchair Control System Based on Electromyography

In order to make life more pleasant and convenient for people with physical disability and mobility problems, this paper designs a wheelchair operation system based on electromyogram. This design extracts four different gestures of the human body to control the four movements of the wheelchair, namely forward, backward, left and right. In order to ensure the user’s safety, this design uses ultrasonic distance sensor to detect the road condition, avoid some obstacles in time, and make the wheelchair move forward safely. This design mainly includes EMG signal collection, analysis, classification and identification, wireless transmission, EMG signal processing, wheelchair control system, safety control system, etc. This design has the advantages of simple operation, high security, stable signal and strong anti-interference, etc.
