This robot flies like a real bat and is not at all creepy

Drones have come a long way in a short amount of time. They now can deliver packages, help in search and rescue missions and will even slice off your finger if your happen to touch one of their spinning rotors. Since we almost certainly will live and work with flying robots in the future, scientists have been looking for a better and safer way to fly. A flying robot bat may provide the answer. 

You’ve got to hand it to bats. Not only are they nature’s only flying mammal, they beat the feathers off most other flying animals when it comes to flight mechanics.
