Arduino-controlled prosthetic hand operates on verbal commands
Here is a really cool instructable about making a prosthetic hand cum arm that operates on voice commands. The project uses a modified version of the InMoov hand/forearm to construct a five-finger prosthetic hand, which is controlled by an Arduino Uno along with a voice-recognition shield. This hand can perform 15 general hand gestures and actions that are used in daily life, such as pinch, peace, thumbs up, point, etc.
