EMG controlled arm prototype forearm flexo-extension

Abstract

Electromyography is mainly used in the assessment of neuromuscular diseases such as muscular dystrophy, myasthemia gravis or peripheral nerve disorders; however its direct relation with limb movement, muscle's electrical signal accessibility (easy to acquire) and the need in our society to come up with rehabilitation oriented practical solutions make it an approachable and attractive option to develop useful control applications. In this project the forearm muscle signal is acquired through superficial electrodes and processed with a designed circuit in which signal amplification, filtering and other conditioning take place. All of these steps are conducive to obtain a final command so that the user can control the arm prototype at his will with just a tiny muscle contraction.
