EMG-controlled robotic hand
A robotic hand driven by muscle signals picked up with gel electrodes and a BioAmp EXG Pill.
Muscle signals are captured with gel electrodes and amplified by a BioAmp EXG Pill. An ESP32 processes them and drives the hand, so flexing a forearm muscle closes the fingers.
The project is an exercise in bio-signal acquisition, embedded processing and human–machine interfaces: getting a usable signal out of noisy skin-surface electrodes, then turning it into a movement that feels responsive rather than laggy.
