Last month we posted a video showing nano quadrotors flying in scarily perfect formation, the product of research at the GRASP Lab at the University of Pennsylvania.


“These flying quadrotors are completely autonomous, meaning humans are not controlling them,” GRASP wrote on their YouTube channel. “They are controlled by a computer programed with instructions to play the instruments.”

The video premiered at the TED2012 Conference in Long Beach, California on Wednesday.

CNET reports that GRASP’s research on quadrators is a step toward coordinating robots for searching areas after a disaster, or for surveillance similar to that done by drones.
