DARPA-funded Nano Hummingbird spybot takes flight    (video)

 

We were plenty impressed when we saw the initial tests of AeroVironment's robo-hummingbird -- now officially dubbed the Nano Hummingbird -- but we can't say they quite prepared us for the final product that the DARPA-funded company is now showing off. Not only does the bot look and fly like a real hummingbird (at least if you don't look too closely), but it packs a built-in camera and a downlink of some sort that's capable of transmitting live video. According to the company, the hummingbird's also able to hover for up to eight minutes, reach speeds of eleven miles per hour in forward flight, and remain stable in wind gusts of five miles per hour -- not to mention make a perfect landing. Head on past the break to check it out in action -- it may well be one of the few chances you're actually able to see one in the wild. 

We've seen plenty of tiny UAVs (or NAVs -- Nano Aerial Vehicles -- as they're also known), but none quite like the robo-hummingbird that's been in development at DARPA-contractor AeroVironment for the past couple of years. While we haven't heard much about it during that time, the company recently completed its most advanced prototype to date, dubbed Mercury, and it's taken advantage of the opportunity to show off all the progress it has made. As you can see in the video after the break, the bot 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, where a hummingbird won't look at all out of place.

Military-backed researchers have built a tiny drone that looks and flies like a hummingbird, flapping its little robotic wings to stay in the air. So far, the mock bird, built for Pentagon mad-science division Darpa, has only stayed aloft for 20 seconds at a time. But that short flight was enough to show the potential of a whole new class of miniature spies, inspired by nature. Darpa just handed AeroVironment, makers of the winged “nano air vehicle,” another $2.1 million to build a hummingbot 2.0.

Ultimately, Darpa program manager Todd Hylton says in a statement, he’d like see “an approximately 10-gram aircraft that can hover for extended periods, can fly at forward speeds up to 10 meters per second, can withstand 2.5-meter-per-second wind gusts.” He also wants the nano air vehicle to operate inside buildings, and be controllable from up to a kilometer away.

AeroVironment, for its part, doesn’t just want its little drone to fly like a bird. The company wants the thing to look like one, too:
