My understanding is that Boston Dynamics videos are heavily staged, their robots are much less impressive in real life conditions. I saw that in an article many years ago, I don't know the situation today.

But it doesn't mean these videos are fake, the robots are real, the movement is real, no hidden cables, no VFX, they are just following a predefined routine in a controlled environment, and I am not aware of Boston Dynamics claiming otherwise.

I mean just look at the linked video, it is comically obvious that it is staged. And well staged I must say.
