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.

Origami is also used to unfold satellites once in orbit.

allow the robot to dissolve in an acetone solution leaving nothing but the magnet behind.

When it is clever enough to realize that is a bad move, I will be worried.
