Pole Dancing: QC Style

Via Alex Tabbarok at Marginal Revolution, this nice video of two quadcopters playing catch with an inverted pendulum. The inverted pendulum is a classic problem in elementary control theory (a fact I recently learned in my Coursera "Control of Mobile Robots" class).  Juggling an inverted pendulum with flying robots is a classic case of hybrid control - in effect, various separate control algorithms cooperatively managing the overall control problem of catch and balance while managing not to collide with each other or anything sol id.  This sort of hybrid automaton is exemplified by robots (or people, or animals)with complex behaviors.
