It is no secret that you can teleoperate robotic hands in various ways. In fact, we have covered a bunch of projects that involve controlling robots using brainwaves and hand gestures. This video shows an EMG-based approach to teleoperation of a robotic hand by decoding the grasping intention at an early stage.
Electrodes and a Cyberglove were used to record muscle activity and finger movement during reach-to-grasp motions. The accuracy is about 90% according to the researchers. More info is available here.
