Piccolo is a pocket-sized open source CNC platform. Using laser-cutting, off-the-shelf hardware and Arduino, you can make your own super-simple 3 axis robot. Attach a brush or pen to make a quick drawing robot, or extend Piccolo with sensors, custom toolheads, or by using multiple Piccolos together. Experiment with 2D or 3D digital fabrication at a small scale!
There are lots of things to consider when laser cutting your Piccolo! Please have a look at our Piccolo Fabrication Guide at https://github.com/DiatomStudio/Piccolo/wiki/piccolo-fabrication-guide
