DARPA contractor shows off tiny robo-hummingbird UAV
tags:From Engadget: AeroVironment recently showed off its prototype of a nano-UAV (also called NAV) dubbed Mercury. It is able to fly about and hover in place by mimicking the wing movement of a real hummingbird and, of course, be controlled completely untethered. What's more, the firm says that the final version will actually look like a real hummingbird as well, and be able to be controlled from up to a kilometer away - even inside buildings.

However I do wonder what the point is over those little remote controlled helos.
I know wings are the only option at the scale of a fly, as the aerodynamic laws wont provide lift at that scale.
But I can buy a remote mini helo for $50 australian right now.
