You have a Quadcopter put a sensors on it and you have autonomous Quadcopter robot but what it can it do? The Robotic Quadcopter from ETH when paired can juggle a ping pong ball. It can sense the ball and will try to catch it. They are much better ping pong player than me.
Aside from Jugging the Quadcopter robots of ETH can they can also dance, play the piano, and perform daring air flips.
