“I was long impressed by BB8 and how it moves. When I then learnt that they made various working models for the film I set about figuring out how to build my own. After a lot of trial and error, misprints and expletives I settled on this design.
This is an easy to build Disney Star Wars BB8 inspired robot. It’s controlled by an Arduino UNO over a bluetooth connection from your smartphone.
It’s a very simple design, so I hope people can build it and add to it their own enhancements.”
