This little bot is the Aquapod from the University of Minnesota’s Center for Distributed Robotics. Aquapod’s designed to tumble on land and at the bottoms of bodies of water like some species of flailing cybernetic horseshoe crab.
Nothing cures boredom like launching shit into the air, which is why you can’t argue with something like the Aquapod. Basically, you hook a hose up to it and it launches plastic bottles using water pressure. Sold! [Aquapod]
