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. 

You can find a link at the bottom of this article to download the 3D printable components.

 Part one in the three part series covers the majority of the electrical assembly, and the creation of his main body.  

Part two covers the construction of BB8's head and the placement of magnets to hold it in place:

Part three will be available soon. When it is I will update this project - please consider subscribing to my Youtube channel to be notified as soon as it is published.

During the creation of part two I realised I would need a hot wire cutter to cut the styrofoam in half. (The bread knife attempt made A LOT of mess and I got in trouble with the other half). I didn't want to buy one as they can be expensive, especially battery powered ones - so I designed my own.  Here you can find instructions on how to build your own battery powered one:
