Why did we ever think that robots had to resemble humans? As we came up with more and more uses for a robot, our ideas changed. Soft, flexible robots are more useful for getting around in uneven terrain, and tiny robots can go places and do things humans could never do. The ultimate soft, flexible robot would be a liquid, right? This robot is semi-liquid, made of polymers, borax, and alcohol, and embedded with neodymium particles throughout so it can be controlled by magnets. The slime is a non-Newtonian fluid that can become solid and then liquid again depending on conditions. It can squeeze through the tightest cracks and stretch to amazing lengths. This slime robot may have innumerable medical applications. (via Geeks Are Sexy)
