          This should be modded insightful. The aircraft have no inertial references AFAIK. All they are is four remotely controlled motors. All of the real-time processing for the control is done elsewhere in the room. The aircraft have retro-reflective markers and external motion capture is used to get feedback for the control system. If you were to try and reproduce their results, the stumbling block would be the price of the Vicon motion capture system with 1000Hz sampling rate cameras. Those aren't cheap.

      If you can shrink the vehicle down to fly size and make it as quite as a fly with the addition of a microphone or a mic w/ a camera it certainly would give new meaning to the expression "fly on the wall". I think the flight path control and anticipating the location of a moving object real time is the impressive part more so than the vehicle.

        The motion is pre-programmed in the sense that once the hoop is flying, it follows the ballistic trajectory. The control algorithm is set up to depend on that, and it choses an optimal trajectory for the quad to get through the hoop, knowing how the hoop moves in the immediate future. If you added a thruster on the hoop to make it non-ballistic, you could easily get the quad to crash. To make the quad become a universal hoop-jumper, whether the hoops move or not, the control system would need to learn how f

It also didn't go through at the easiest part of the hoop's trajectory (the top) Presumably, with appropriate programming, it could pass through a hoop that was swinging or moving in any other regular pattern.
