Our nano-quadrotor robots are made to be as lightweight as possible: less than a fifth of a pound and palm-sized. They can do an aerial backflip in half a second, accelerate at two Gs, and fly rotor blade to rotor blade in three-dimensional formations - and they do all this autonomously.

The big mathematical challenge for flying robots is making them move in six dimensions: x, y, z, pitch, yaw and roll. We create 3-D obstacle courses in the lab - windows, doors, hula-hoops taped to posts - and ask the robots to fly through. It looks like a Harry Potter Quidditch match.
