Abstract

In India most of the people lost their hand due to road accident, disease and soldiers lost their arm in war. This paper describes the design which controls the hand motion and wrist motion of Myoelectric controlled prosthetic arm using cortex M3 microcontroller. In this design electromyogram signals are generated by contracting the muscles of biceps and sensed by electrode sensors. Electrode sensors produce the electrical signals and these signals are processed by microcontroller and achieve the supination motion from 00 to 750 and pronation motion from 00 to 850 in the wrist of hand12.
