Georgia Tech models swimming, cargo-carrying nanobots

Georgia Tech models swimming, cargocarrying nanobots

The nanobot war is escalating. Not content to let Penn State's nanospiders win the day, Georgia Tech has answered back with a noticeably less creepy blood-swimming robot model of its own, whose look is more that of a fish than any arachnid this time around. It still uses material changes to exert movement -- here exposing hydrogels to electricity, heat, light or magnetism -- but Georgia Tech's method steers the 10-micron trooper to its destination through far more innocuous-sounding flaps. Researchers' goals are still as benign as ever, with the goal either to deliver drugs or to build minuscule structures piece-by-piece. The catch is that rather important mention of a "model" from earlier: Georgia Tech only has a scientifically viable design to work from and needs someone to build it. Should someone step up, there's a world of potential from schools of tiny swimmers targeting exactly what ails us.

Researchers power microbots made of bubbles with lasers

They may not be "robots" as most have come to expect, but these so-called microrobots developed by a team of researchers from the University of Hawaii at Manoa do have at least one thing in common with many of their mechanical counterparts: lasers. As IEEE Spectrum reports, the bots themselves are actually nothing more than bubbles of air in a saline solution, but they become "microrobots" when the laser is added to the equation, which serves as an engine of sorts and allows the researchers to control both the speed and direction of the bubbles. That, they say, could allow the bots to be used for a variety of tasks, including assembling microstructures and then disappearing without a trace when the bubble is popped. Head on past the break for a video of what they're already capable of.
