The more practical app of this personal radar project is in robot navigation systems—always a good sign when the functional side of something is robots—but it's small enough to be mounted on a car's bumpers to help spatially challenged drivers navigate the rollercoaster of parallel parking. (Unless they've got a schmancy car that does it for them.) Expect to see a smaller, cuter version with cellphone integration for Japanese school girls any day now. [Pyro Electro]
