Want to give the $150 Sphero BB-8 a run for its money?
According to 17-year-old Angelo Casimiro, all you need is a trip to the hardware store and about $120 for mainly an Arduino Uno, some wheels, a beach ball, and a few days to get your hands dirty.
After some soldering, paper macheing and making your own rechargeable batteries, Casimiro’s tutorial on Instructables proves that building your own droid isn’t rocket science.
The end result is impressive, and lets you control your own BB-8 droid using a smartphone.
