This project was inspired by "The Draughtsman" automaton made by Jaquet-Droz. The design was made in SolidWorks. For his mechanism, the cam had to be very precisely read to move the pen very carefully to produce a shape. The cams were designed such that they could be easily accessible and replaced to make a different drawing. Much of the cam following set up is led by two arms that then move a pen holder.
