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)
I like the dragonflies and hummingbirds, too. The hummingbird actually comes without the realistic outer shell, which is an option. But I think many people prefer the realistic ones that mimic their original inspiration.
Ann thanks for the slideshow. All of them are amazing and I personally like ebee, dragonfly and hummingbird robots. It would be an amazing experience if we can attach those robots on our back and fly like bird.
This is a great compilation of images of some of the most ingenious flying robots that have been invented so far. I especially love the ones modeled after dragonflies and hummingbirds. They're almost as elegant as the natural beings they emulate. The RoboBee is incredibly clever as well; I can imagine a swarm of those being quite effectively used!
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
Anyone who’s ever moved files from a hard drive to a computer has sat patiently waiting for the transfer to complete. But what if this process could be done wirelessly, without having to connect devices with cables, and in seconds?
