Assignment: Design, fabricate, and program an arm that is able to draw letters with a sharpie.

One major product for my robotics controls class was to fabricate and program a double-jointed arm with the ability to draw using a sharpie. This robot was able to write letters with the sharpie (albeit slowly), and was made using CAD-modelled 3D-printed parts, and programmed using Arduino and C++.
