Magnetic 'Micro-Robots' Could Lead to Tiny Automated Factories

Remember those old electric football games that used a vibrating tabletop surface to send teams of tiny NFL players scrambling around the field?

Well, researchers at SRI International are developing a super-miniaturized, high-tech variation on the theme in which tiny worker robots shimmy around a circuit board in a micro assembly plant. The 'bots are guided by magnets underneath the surface, and work in sync to assemble electronic parts and small mechanical systems.

The Diamagnetic Micro Manipulation (DM3) system uses magnets under the circuit board to guide the tick-sized robots in precise patterns. Because of their small mass, the bots can move very quickly and in the demo video below they appear to jump like fleas. Read more...
