Summary: 

Most robots which are used to draw do so with complex digital control and multiple motors. Inspired by automaton in ancient times, we aim to create a robot that can encode drawings mechanically. The design constraints we have include 1) how to achieve at least 2 DOF motions with only one motor 2) how to encode a fairly complex and detailed drawing, like the longhorn, into mechanisms and 3) how to construct our robot to draw precisely and repeatably. After many iterations, we were able to achieve our goal and satisfy the design constraints by using a helical cam, a follower system using sliders, a cylindrical drawing platform and a simple gear train. The cam provides motion in the Y-Axis, while the cylinder provides motion in the X-Axis.
