Open Source Prosthetic Arm Controlled By Muscle Movements

Gustavo Brancante is working on a very interesting project that let you control a prosthetic arm with your muscle movement using open source technology with InMoov Hand (which can be 3D printed), Arduino Uno R3, and Olimex Electrocardiography electromiography shield (SHIELD-EKG-EMG). This is called a Myo-Electric Prosthesis.

Gabriel wrote a tutorial to use his “open arm” which I’ll summarize here.

On the hardware front, you’ll also need a UDP compatible Wifi Shield configured as a UDP server with a fixed IP in the same LAN as the smartphone, and 57600 bps.

TouchOSC (for smartphone and Workstation) is used with the following layout for calibration and feature selection.

Finally load the program below to your Arduino board:

Once everything is connected together, you should be able to do that:

The demo looks impressive, but this is still work in progress, and next step will be to use a four channel EMG instead of the single channel Olimex EMG shield to be able to detect more advanced movements.
