One robot can can crawl on four "legs" without the need for any sort of motor. Another can jump to seven times its height. Both can fit on the palm of one hand. Yes, these are not your average robot and are not even close to any humanoid robot you may have seen. They look more like metallic origami figures, and that isn't that far from the truth. In fact, the researchers at the École Polytechnique Fédérale de Lausanne or EPFL in Switzerland call these robots as "robogami".
