The U.S government (and the Pentagon, specifically) has created the Hummingbot. This remote-controlled device is built with the same mechanics as a hummingbird.
The division of the Pentagon constructing the robot, DARPA, has managed to get the bird to stay hovering for around 20 seconds (enough to see mass potential and continue development and get an extra $2.1 million to keep going).
This nano air vehicle (NAV) is expected to be able to hover for extended periods and travel at around 10 meters per second. Designers also hope to control the Hummingbot up to 1 kilometer away. While you’re admiring nature, it might be the Pentagon spying on you (ooooohhhhhhh).
