A team of engineers led by Matt Keennon at California-based aerovironment developed the Nano hummingbird for the Defense Advanced Research Projects Agency. The Nano hummingbird is composed of four components; low-res camera, 6.5 inch wings, transmission and plastic shell. It is designed to mimic the flight of a hummingbird. It can fly up to 17.7 […]
Helicopters are a very unique human-made flying machine.

This makes them more analogous to birds, which use twisting of their wings to produce lift and […]
