The lab bought some robots to teach junior-high students how to think about programming. It basically runs on an ATMega328 with an Arduino bootloader, 2 motors, and 5 line sensors. It has a buzzer that plays classical music too. If you want to get the included AVR programmer to work with OSX, prepare for some gnarly firmware updates. This is my first test run after uploading the included line-following example code.

Next step, integrate color sensors!
