In principal, a control system for doing this is easy enough to imagine, hard to do: with a bicycle when you start to fall one way, you turn into that direction. We know how to do critical damping with control systems. We know how to do lead-lag compensation, etc. This is the first time I have seen it done with a bicycle. You know there will soon be robot unicycle riders, and of course the perfectly logical next step is racing them.
