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.

CIA dragonfly drone almost beat modern UAVs by 40 years, was swatted (video)

Cold war era CIA insectocopter predates nano UAVs by 40 years video

US intelligence agencies were just as obsessed with drone spying 40 years ago as they are nowadays -- only then, it was pipe-smoking entomologists and watchmakers who were in charge of building prototypes. Back in the '70s, the CIA needed some kind of miniature flyer to deliver an audio bug, and after considering (and rejecting) a faux bumblebee, decided that a robotic dragonfly would be the best option. The wee UAV used a "miniature fluidic oscillator" as a motor and was propelled by a small amount of gas. It was somehow guided by a laser beam, which served double-duty as the "datalink for the audio sensor payload," according to the CIA Museum. Unfortunately, the insect-based mech proved too difficult to control, especially with any degree of wind, and was eventually scuppered -- all that's left of the now-declassified project is in the video after the break.
