A few months ago, Jordan and I decided to build a chalk drawing robot. Our plan was to enter the Amazement Square 2016 Chalk Festival, draw an exact replica of the Mona Lisa, and walk away with the gold. We built Chalkbot over the course of three nights. Jordan focused on the electronics, wiring the stepper motors and programming the Arduino with a gcode interpreter, while I built the gantry and other mechanical aspects. Justin was there to lend some help in both realms.
