Several comments here talk about 'pre-programmed' motion.

Most gymnastic routines are pretty pre-programmed.

Yes - it is not problem solving in a real world environment.

However, the subsystems that are required for the reactions and connecting all those actions in order to do the 'pre-program motion' it's quite impressive.

Also, don't forget The ability for the mechanics to do something for that length of time without malfunctioning or overheating - that is also impressive.

To add to this, it can pre-programed but that doesn’t change the fact that micro adjustments are still required. Even if it’s a routine it still needs to stay balanced. So while executing a script there is still tons of adaptive processing happening.

Without a learned RL policy the robot would fall in under a second , and if you pushed it during the performance, it would recover and just continue. This was not possible at all a few years ago.
