B) there’s a long tail of individual tasks it’s uneconomical to build purpose-built robots for each individual task. But it’s economical to have 1 robot that can do all of them.
The point is, human shape plus general purpose intelligence is an amazing combination to resolve the “long tail”.
Without the intelligence part, the body is useless.
Perhaps Boston Dynamics has that part resolved now too.
Do they? A human can both chuck kilograms of stuff across a room or kick in a door, but then pick up a single hair off the ground, or feel and manipulate (things even lighter than) a literal feather.
Robots can certainly do things more repeatably, if not more precisely.
But the rest of the human body is not useful in a factory environment, so the arms could be mounted on a mobile base that does not have any resemblance to a human.
I dunno, a legged design is pretty useful for navigating complex environments. The arms and legs have to attach to something so you've still got some sort of torso. About the only thing you can easily do away with is the head I think.
But certainly a bipedal design seems unnecessarily complicated unless you need it to climb ladders inside narrow tubes or something similarly specific. I feel like a quadruped with 4+ arms mounted on top and many-jointed fingers might be ideal (both in terms of utility and also creepiness).
But of course the wheels could be replaced with feet where that's needed.
