The robot moves by pumping air into its legs, which are inflatable chambers that are hollow on the inside. When one leg is inflated and the others aren't, for instance, the inflated leg bends. The machine can also easily transition from a crawling to a walking position, and vice versa. At this point in time, the current model still has to be tethered to an open source board and an air pump, but the team is working on making a smaller version that can move freely.
