A number of artistically inclined robots showed up at this year’s Maker Faire, but The Drawing Machine really stood out among the competition.

Winner of a Maker Faire Editor’s Choice ribbon, Harvey Moon’s Drawing Machine takes any black and white JPEG image and transforms it into a robot-drawn work of art. The machine is controlled by custom software that runs on an Arduino, and due to a degree of randomization in the code, each piece ends up being completely unique.

Moon didn’t expect to be at Maker Faire this weekend — Make magazine invited him to attend the event just two weeks prior.
