DARPA has recently released a video demonstrating the evolution of its hummingbird-like Nano Air Vehicle (NAV) from 2006 until now.

In 2005, DARPA announced the Nano Air Vehicle (NAV) program and its goal to develop agile and flyers system that could fit in one hand. This video chronicles the development of a “hummingbird” flyer by Aerovironment from concept to prototype demonstration and introduction to the public.

Next step, a similar vehicle as big as a common house fly, used to film your every move. Scary thought, isn’t it?
