This new hummingbird drone was designed and built by researchers at Purdue University. The coolest part of it is that it actually flies like a hummingbird. The 3D-printed body has wings made of carbon fiber membranes. 

It has an electrical sense of touch and AI algorithms that can analyze those touches, basically creating a map to see in the dark. Bio-inspired robots and drones have been around for a long time, but this one seems closer than ever. Check out the video below.
