The Egg-Bot is an open-source art robot that can draw on spherical or egg-shaped objects from the size of a ping pong ball size to that of a small grapefruit — roughly 1.25 to 4.25 inches in diameter (4-10 cm). 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.
Use it to personalize Christmas ornaments or impress your friends with masterpiece Easter eggs. The Egg-Bot 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.
