The Untethered Miniature Origami Robot, created by scientists at MIT is a 1.7cm square device powered by a neodymium magnet and four subsurface electromagnetic coils that allow the robot to assemble itself like an origami sculpture, walk, climb, carry objects twice its weight, swim in shallow water, burrow and dissolve in an acetone solution leaving nothing but the magnet behind.

The potential, according to the research team, is for medical nanobots capable of killing cancer cells or unclogging arteries.
