More precisely “AeroVironment Flapping-Wing Nano-UAV”, it’s a DARPA (Pentagon) project for a small robotic hmmingbird made to serve as spy bots.
It has evolved a lot, but still can only fly for about 20 seconds.
Only a matter of time though… which is kinda scary if our future ends up being some sort of 1984-esque dystopic one.
Small hummingbird is watching you. 😛
