Quadrotor's juggling with each other

Here they are juggling (this is the latest)


here's the juggling quad from december

here's one balancing a stick

here's several putting something together

here's one flying through obstacles

This is my favorite, it shows how they work

All of them so far have required a specially prepared rooms, with lights on the ceiling so that they can orientate themselves. However, integrating something like a smaller version of a kinect will allow these things to be fully autonomous. I do not doubt that our future will have these things everywhere.
