The Nano Air Vehicle, a DARPA-funded hummingbird-like demonstrator robot made by AeroVironment, flaps its wings to fly in any direction. The remote-controlled Nano can hover with precision like the real bird, and it can fly clockwise and counterclockwise. It weighs 19gm (0.67oz), including batteries, video camera, motors, and communications systems, and it has a wingspan of 16cm (6.3 inches). Its size and weight are within the range of real hummingbirds, and, like them, it uses its wings for control and propulsion. The Nano can hover continuously on its own power source for eight minutes. It can shift from hovering to a forward flight speed of 17.7kph (11mph). While hovering, the Nano can tolerate side wind gusts of up to 8kph (5mph) without losing more than 1m (3.28 feet) of altitude. (Source: AeroVironment)
There are varying definitions of what makes a robot autonomous. Some flying or ground robots can carry out missions autonomously, according to yars' definition, but also have communication with a remote pilot. The point of that link is so the pilot can decide to tell the robot to do other things once the pilot has examined video sent back by the robot. This combination capability is often used in military applications.
FYI, autonomous vehicles are exactly that - they have the resources to carry out their assigned mission without any intervention from remotely-located pilots. Remotely-piloted vehicles are another class, altogether.
Yes, good to have choice, but probably realism is best. I seem to remember some really beautiful artful-like flying robot that you wrote about (I can't recall the name nor the post) and I was suprised not to see it in the slideshow. It was one of the loveliest (if I can use that word!) flying robots I'd ever seen. Do you remember, Ann? Or maybe someone else wrote about it...
Nadine, I agree--still slides of these machines don't tell the whole story. But if you go to YouTube and enter "Robo Raven", you'll find at least one recent video showing its moves, and also being attacked by a hawk.
AnandY, interesting idea, but they've all been designed to be as light as possible, and couldn't carry our weight, That said, there are efforts by some of these folks to give humans flying suits. Check out the video here: http://raffaello.name/dynamic-works/actuated-wingsuits
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
