Myoelectric Control

This is my video entry for the IEEE Maker Project 2016. This project uses 3D-Printing technology to manufacture the InMoov robotic hand (designed by Gael Langevin). High-torque DC servo motors were used as actuators for the bidirectional tendon system. An Arduino Uno Rev3 with IO expansion shield was used to generate the PWM signals and control servo angle of rotation. The Thalmic Labs Myo, an armband with electromyography (EMG) sensor and embedded ARM processor for pattern recognition, was used to distinguish which muscles in the forearm are innervated by the user. The classified EMG signals then serve as input stimulus that triggers a transition in the grasp/posture enacted by the 3D-printed robot hand.
