It doesn’t look like they’re autonomous to me, it looks like they have a pre-programmed set of movements (like the kick-variants we’re seeing, and the “get up” motion), and being controlled by someone outside the ring. That also fits with the way they’re missing: it’s hard to get proper alignment when you’re looking from the side, and the pattern for how they’re missing looks a lot to me like how you often miss if you try to line up e.g. a remote controlled toy car on an opening to drive through when you’re sitting off to the side.
