Check out this swarm of flying nano-quadrators developed by the robotics team from University of Pennsylvania’s GRASP Lab. It is truly eerie/amazing to see the team of robots jetting around through the air in perfect formation. And it seems only a matter of time before you’ll find these outfitted with cameras roaming the city streets or maybe with machine guns patrolling a war zone. They can fly in 3-dimensions and even avoid obstacles. I’m impressed!
