The US military’s UAV fleet will soon be getting a small addition — DARPA’s hummingbird-shaped covert surveillance drone.
It mimics more than just a hummingbird’s looks, mind you. By copying the bird’s aerodynamics and wing movements, the NAV is able to hover for eight minutes while easily moving in and out of buildings. The tiny, 10-gram flier is also able to operate in windy conditions — withstanding up to 5MPH gusts. The drone is controlled via a video stream from its deployment aircraft.
