Nano quadrotors, helicopters with four rotors, have been developed by the University of Pennsylvania’s GRASP Lab. And the small robots are quite incredible, especially in swarms. From cnet:
The quadcopters are able to flip over and maintain flight. More amazing (unnerving?) is their operation in formation. Based on commands, 16 quadcopters change direction, land, navigate past obstacles, and even fly in a figure-eight formation.
Coordinated formations! And a figure eight without crashing into each other. It really looks like something out of a scifi movie or a video game. Definitely a kid must see.
