In addition, an onboard accelerometer allows it to detect collisions and perform obstacle avoidance (if you program it to!) and lights up an autocycling RGB led after impact. It uses a protected 18650 cell with an onboard USB charger.
The intent was to develop a platform that was cheap enough to give away to students who wanted to build one, and it is currently being used in a high school summer camp program.
All software files and the hardware gerbers are up on the github: github
and the build directions and BOM are on the github wiki: github wiki
The hardware files and ordering directions for PCBs are up here
If you are curious the design process struggle was documented (poorly) here
Hope someone finds this interesting or useful!
