First Light Painting Tests

I had the idea to mount my tablet onto the robot and then use it for light painting! :) This time the tablet receives the XBox 360 Controller commands over a PC via Wifi and sends it down to the Arduino. The Arduino itself calculates its position in space by accumulating the distance each wheel drives. So the error gets larger and larger over time. However it gives the light painting a nice imperfect touch! Click on the images to load larger versions...
