Rotating track flipper design

I see a few of these tracked robots that have a set of tracks that pivot 360 degrees around. I'm kinda stumped on how to build the flipping thing while still using COTS motors and tracks. Are all of these completely one offs, using some kind of custom-built sleeve that controls the pivot of the track, while the drive of the tracks is connected in the middle of the sleeve? How does this work? I've hopefully embedded a video that has an example of what I'm talking about. If you search youtube for "stair climbing robot" you'll run across a dozen or so different robots that use this design.
