Absolutely wonderful to see in motion. Things like this brought to life are one of the Most exciting uses of AI to me.

Where’s the AI, did I misread the post?

> To select which ones were best, each variation got assigned a ‘fitness’ score based on its walking speed, clearance and material use. I also rewarded extra points to variants that had leg tips which moved more horizontally and more smoothly during the lowest third of their cycle to make it favor solutions in which a group of three legs would work together to minimize bobbing and foot slip.

I am not sure what approach was used here, it sounds like RL or maybe just simulations. I am not sure I’d say this is AI.

I think it was just a genetic algorithm.

I guess it depends on your definition of AI. I personally don't consider the LLMs AI. Very useful, but to me not AI.
