This is crazy, if they are developing this and showing it publicly, just imagine what else they have!
AeroVironment Develops World’s First Fully Operational Life-Size Hummingbird-Like Unmanned Aircraft for DARPA.[youtube]http://www.youtube.com/watch?v=xolH02Zba04[/youtube]
The Nano Hummingbird was developed by AeroVironment for the US Defence Advanced Research Projects Agency (Darpa) and may one day be used for rescue and surveillance missions for the military.
The prototype uses its wings to achieve propulsion and maintain balance, and it is equipped with a small camera that can stream live video.
The hummingbird has a small wireless camera, and can fly for around 10 minuets. It was obviously developed for military and civilian use as a small remote controlled spying device that would go unnoticed and blend naturally into the surrounding environment.
The hummingbird is really a working prototype to see if the technology would work in the real world — scary spying robotic birds!
