Robotic Insect Takes Off

Researchers have created a robotic fly for covert surveillance

A life-size, robotic fly has taken flight at Harvard University. Weighing only 60 milligrams, with a wingspan of three centimeters, the tiny robot's movements are modeled on those of a real fly. While much work remains to be done on the mechanical insect, the researchers say that such small flying machines could one day be used as spies, or for detecting harmful chemicals.

"Nature makes the world's best fliers," says Robert Wood, leader of Harvard's robotic-fly project and a professor at the university's school of engineering and applied sciences.

The U.S. Defense Advanced Research Projects Agency is funding Wood's research in the hope that it will lead to stealth surveillance robots for the battlefield and urban environments. The robot's small size and fly-like appearance are critical to such missions. "You probably wouldn't notice a fly in the room, but you certainly would notice a hawk," Wood says.

Recreating a fly's efficient movements in a robot roughly the size of the real insect was difficult, however, because existing manufacturing processes couldn't be used to make the sturdy, lightweight parts required. The motors, bearings, and joints typically used for large-scale robots wouldn't work for something the size of a fly. "Simply scaling down existing macro-scale techniques will not come close to the performance that we need," Wood says.

US DEFENCE are involved eh? Oh I wonder why? Big Brother is watching!

But really, is this an amazing feat of technology or another advancement in the 'watching' of the global population?

Any thoughts?

(sorry if this has been posted already - I did search)

This is pretty cool news and they actually show a pic of what it looks like. If a picture is worth a thousand words then this is a perfect example.

This is what we can look forward to in the upcoming decade. What the exact mission will be can change if they can add things to the design of this bug. I heard that Israel has something like this but I think it is bigger. Great thread.

That's really cool, and I like the shape/design, functional yet geometric futurist artesque.

So will these new robot flies become the food of the new robot birds.

Like this one.
