How about a walking iPhone robot? Meet the PuchiRobo. This system can “turn anything from a beer can to a tissue box into a bipedal ‘bot — used to give iPhone legs.” Video after the break.
At the moment the whole setup is a little rudimentary. Kazu’s PuchiRobo legs need to a computer to keep them moving, though he’d like to add a chip to the setup so that it can process the movements on its own.
