Using Electromyography-Based Controls to Direct a LEGO Mindstorm Unit

This project explores the use of electromyography (EMG) controls to direct a LEGO Mindstorm unit, detailing the PIC-timing interface, A/D converter, filtering methods, EMG algorithm, and RS232 serial port. The study focuses on signal processing, regardless of samples, using a 60 Hz notch filter and bandpass techniques, along with a special EMG algorithm. The system features a PIC18F4525 microcontroller, Bluetooth communication with the NXT unit, multiple inputs and outputs, and own software for control. References include studies on muscle contractions, EMG evaluation, and data sheets for relevant components.
