It seemed pretty obvious to me. Yet, I was pretty impressed nonetheless, I mean, the sheer dexterity of movement of these things with a human-hand anatomy surprised me, I don't think I've seen it before, and didn't know carnival toys are at this level yet. Is it a commonplace technology? It seems like it must have some practical uses, to be able to operate an almost-human body remotely like that. But, as I've just said, I don't think I ever saw this, only clunky specialized robots with poor movement control. And Boston dynamics pre-programmed toys.
