I can barely get my Ar.Drone to land on the box it came on (I am not a good drone pilot), but these quadrocopters from can frickin' juggle (with thanks to Donnie Berkholz):
One small concession to my pride is that they're not being manually operated: check out this post from ETH Zurich's Flying Machine Arena to see the physics and math and vision processing behind the automation that makes it work. How long before there's an all-robot acrobatics show from Cirque su Soleil? I'd totally go see that.
That's all from me this week. Have a good weekend!
