Scarab, the moon miner, was developed at the Robotics Institute of Carnegie Mellon. He's an awesome little guy designed to mine "hydrogen, possibly water, and other volatile chemicals" for use at a future moonbase. I didn't know water was a volatile chemical, but whatever. It runs off solar energy, and when there isn't any, it utilizes a "radioisotope source" for power. Which is good news, because I've been waiting for an RC car that runs off decaying uranium.
