Quadrocopters throw, catch, and balance an inverted pendulum

Quadrocopters throw, catch, and balance an inverted pendulum:

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...
