Pentagon Puts Out Call For Liquid Robot

The Pentagon's DARPA (the people who brought us the Internet) put out a call for proposals for a shape-shifting "chemical robot," or ChemBot, that can pour itself into small spaces and creep under doors, then TRANSFORM ITSELF on the other side back into its regular shape. The Pentagon wants a softball-size robot that can squeeze through a 1-centimeter opening, then go back to its original size in under 15 seconds.
