What is an EggBot?

The EggBot is a compact, easy to use open-source art robot that can draw on spherical or egg-shaped objects. Super adjustable; designed to draw on all kinds of things that are normally "impossible" to print on. Not just eggs but golf balls, light bulbs, mini pumpkins, and even things like wine glasses-- with a bit of work.

Objects printed with EggBot

Use it to personalize Christmas ornaments or impress your friends with masterpiece Easter eggs. The EggBot is not just a cool gadget; it’s also a great introduction to do-it-yourself robotics. All of the electronics and software are designed to be hackable and repurposable, so you could easily computer control an Etch-a-Sketch or create something totally new.

The EggBot software allows you to control the 'bot from within Inkscape-- a superb freeware illustration program -- on Mac, Windows, or Linux computers. You can draw an image directly, trace a photograph, or import designs from other programs. You can also control the EggBot directly from many other programs that have the ability to send serial commands over a USB port.
