This is a simple EMG Controller for the Galileo Bionic Hand Prosthesis
At this moment you can control the prosthetic through serial port by sending:
- '1', for "Power Grip" selection
- '2', for "Point" selection
- '3', for "Pinch Grip" selection
- '4', for "Lateral Grip" selection
- '5' for "Tripod Grip" selection
You can customize the actions by modifying PWM values (microseconds) on finger position function (values depends on the way that the hand was built it).
Also, you can easily watch the data using a serial oscilloscope
- Serial_Osciloscope(TRUE,RAW) to watch raw signals, FALSE deactivate this feature
- Serial_Osciloscope(TRUE,RECTIFIED) to watch rectified signals, FALSE deactivate this feature
- Serial_Osciloscope(TRUE,SMOOTH) to watch smooth signals, FALSE deactivate this feature
Nokia 5110 display implementation for visual feedback will be add later, we have to modify libraries and fonts in order to improve the functionality. The main idea is to change of action by pressing a push button and change thresholds using a potentiometer.
Videos, Bill Of Materials and Tutorials to build the shield and the hand will be posted later, more information on:
