amphibious robot that crawls around by falling over itself. Literally. Developed by researchers at the University of Minnesota's Center for Distributed Robotics, Aquapod uses two carbon fiber arms and a servo motor system to somersault itself around, like an inebriated horseshoe crab. It's certainly not the swiftest of bots, but this guy's durable enough to move across rough terrains and, per its nickname, is completely waterproof and in full control of its buoyancy. Creators Andrew Carlson and Nikos Papanikolopoulos say their $2,000 brainchild could one day be used to monitor fish populations and conduct underwater experiments -- or to simply scare the bejesus out of beach-going children.
