Apparently, balancing a pole on top of a flying quadrocopter robot wasn’t challenging enough for the researchers at ETH Zurich’s Institute for Dynamic Systems and Control. Their latest project has two quadrocopters playing catch with a precariously balanced pole – the first robot launches the pole into the air, while the second robot deftly moves into position in less than a second to catch it as it falls. The incredible precision flying achieved by the team can be seen in a video after the break.
This video shows three quadrocopters cooperatively tossing and catching a ball with the aid of an elastic net.
Fast, safe transitions of multiple quadrocopters are often required in the Flying Machine Arena. In this video, we use an algorithm based on convex optimization to plan collision-free trajectories.
Ball juggling experiments with quadrotors in the ETH Flying Machine Arena – By Mark Müller, Sergei Lupashin and Raffaello D’Andrea. This is not human-piloted. The vehicles/ball are tracked by an overhead motion capture system and controlled by a pair of computers.
