This is amazing but it also made me realize I just don’t trust these videos. Is it sped up? How much is preprogrammed?

I now they claim there’s no special coding but did they practice this task? Special training?

Even if this video is totally legit I’m but burned out by all the hype videos in general.

they seem slow to me, I was thinking they're slow for safety

They appear to be realtime, based on the robot's movements with the human in the scene. If you believe the article, it's zero shot (no preprogramming, practice or special training).
