This SphereBot is based on the EggBot which is an open-source art robot (drawbot) that can draw on spherical or egg-shaped objects.

This EggBot design has a perfect functionality (the same as the original EggBot professional), a perfect cable and microcontroller arrangement, and a perfect cost as it uses a minimum list of parts (with one V-Slot Linear Rail size20mm x 80mm and length 500mm you can build 3 EggBots!)

My version of the Mug Plotter designed by Teed http://edinburghhacklab.com/ . Also used the Eibotboard from the original eggbot from evilmadscientists http://shop.evilmadscientist.com/partsmenu/188-ebb A huge thanks to Hexitex for his brilliant Four jaw chuck http://www.thingiverse.com/thing:5791

Another slight variation of Niko's Eggbot using Openbuilds V-slot and other 3d printed parts.

To build a simple EggBot

This is my build of Niko's (gianakop) Egg Painter. Egg decorating is something many Christians do for Easter Sunday and the Easter (Paschal) Season that follows. This will be my initial use for the build, but also with minimal modification to be able to write/paint on other round objects like Christmas ornaments, coffee mugs, etc. Many people also decorate eggs for purely secular reasons.

After seeing different egg bots designs, I decided to incorporate my own design.
