Here is an interesting video that came my way via reader "Nino". It's a look at some rather amazing technology that is developing right now, and I suspect very few are aware of it.
Link if video does not play: Quadrocopter Pole Acrobatics
The video shows a quadrocopter capable of dynamically balancing an inverted pendulum (a stick weighted at the bottom), but also flipping the stick to another quadrocopter that determines the optimal position to catch it without losing balance.
Technology marches on whether anyone is aware or not. People do become aware as markets for technology develop.
