A Robotic Arm

I wrote just the code for controlling this robot. The mechanical structure isn't mine. It had 3 degrees of motion. The robot was already assembled. The controlling chip was an ATMega16. A Potentiometre was used to sense the movement of the arm, potentiometers were used. One was used to indicate movement of the finger, other for sensing the movement of the wrist and the last one to check for the movement of the elbow.

In this video we are simply rotating the potentiometer to control the arm. Watch how it almost falls over.
