Plotting Electronically

For just a few Euros, a basic plotting robot can be constructed. Based on two servos, an Arduino and a pen, it is hard to build a more simple construction than this. From the video, you can see that cheap servos combined with far from ideal mechanics introduced quite a bit of errors into the system. The result can be referred to as artistic – or noicy. Still, the idea of a polar-coordinate-based plotting robot is not new.
