A fun project to build a drawing bot which uses linear motors, belts, and a servo to take digitized line art and physically draw it on paper, in a plotter like fashion. Here are a couple resources which are helpful.
One of my intentions is to draw golf course layouts and their corresponding contour lines, this site has the relevant height lines.
Use a Inkscape extension to convert SVG to line art: https://github.com/love-open-design/LY-Drawbot-Tool-by-LOD
