Obviously some sort of sensors.......... mainly to prevent running into other stuff (robots, elements, etc). Or some sort of technology that will prevent a robot from entering or running into a certain area; and if a robot does, it will lose points.
Last May, during Space Day, Dave came to me and told me about how he was talking to Woodie on the phone and
612's ElectronicBabyWalker might have helped shaping 2007 game.......

PS just a guess, don't take it seriously........
PPS Dave, don't kill me if this happens to be right....
