Drawing Arm with Arduino

Can you imagine to build a robotic arm that can draw? Actually [acorv] realized a good prototype.

I wanted to build a drawing arm that could write. My first version wasn’t good enough, so I built this one. I used timing belts and pulleys to improve the resolution. Stepper motors are driven by a Motor Shield on top of an Arduino UNO. On the tip, a servo motor allows the pen to go up and down. For input, I used a touch pad.
