A robot named Balto designed and built by undergraduate students at Caltech working with graduate students at Caltech and JPL, which Caltech manages for NASA, took to the field in the first phase of the Defense Advanced Research Projects Agency (DARPA) this summer, where the Caltech-JPL team took second place. The SubT Challenge is an international competition sponsored by DARPA to advance technologies to autonomously map, navigate, and search underground environments. Professor , the leader of the Caltech section of the team says "The drones are our air-based scouts, and Balto is our eyes and ears on the ground. It's light, cheap, and fast. It can get in, find out what's going on, and help us to make decisions about how to proceed."
