Artist Harvey Moon admits that he has always had a difficult time drawing. Naturally, then, he built a robot to do it. Moon’s machines use the same pens that you’ll find on your desk right now. However the pens are moved around, picked up, and put down on a sheet of paper by motors running on a program. His first drawing machine works vertically with only two simple motors. The amount of detail put to paper by the machine, though, is astounding. Check out the video to see Moon give a more detailed explanation of the way the drawing machine works.
