Autonomous copter flies with astonishing precision



Who knew a quadrotor helicopter could fly with such grace and perfection? This autonomous radio-controlled aircraft was programmed by the geniuses at the GRASP Lab at the University of Pennsylvania. Now that is some sweet flying.

Each of this quadrotor bot's moves is transmitted from an outboard computer to the helicopter via 2.4GHz XBee wireless networking. According to its builders, "The quadrotor knows the location and orientation of the window from the motion capture system."

And how does it stick to the wall? Velcro.
