This drawing robot is driven by 2 stepper motors, an Arduino Uno and a G-Shield. The modular design of the machine allows being scaled up in order to produce gigantic drawings, by only extending the length of the timing belt. In order to keep a good drawing precision, the timing belt needs to be tensed: some long m16 hex nuts and bolts are attached to the weights holder. Finally, all the pulleys have bearings embedded in order to minimize the friction.
