Electromyographic control of a robotic arm for educational purposes

We describe an experimental and educational tool based on the design and development of a robotic arm controlled by EMG surface signals, captured at the biceps brachii muscle and digitally processed. We present the hardware design for the biosignal pre-processing and describe the post-processing and the microcontroller for three servomotors. The design has been used in classroom to promote and integrate different BME curriculum knowledge.
