Note that this experiment (balancing an inverted pendulum, then moving on to balancing an articulated inverted pendulum) is one of the examples from the original Papert LOGO papers of neat robotics problems which grade schoolers can understand and start working on (using the LOGO turtle or similar), but which can be refined as far as the student wishes to take it.

A crucial difference is that a 2-link pendulum is a chaotic system. It's much harder from a control-theory point of view.

I agree. While the inverted pendulum is fairly straight forward to implement with a PI controller, the 2-link pendulum is quite an accomplishment.
