I can see that for the factory floor, but there's no particular reason for "it" to be "humanoid".

It's basically a robot arm with mobility at that point, and if you need more than one, just have more than one robot wheel into place. There's no particular reason to have two arms.. one, or three, or five are all sensible numbers. Heck, a chassis supporting a variable number of arms and other appendages (sensors and so on) is plausible, and the control system looks more like an ant-colony mind than a human one.

Which is a long-winded way of saying, there's no particular reason to link embodiment and cognition at the individual arm level in a factory scenario.

On the factory floor, all the tasks that were a good fit for "a robot arm bolted down to the floor next to the assembly line" are already performed by robot arms bolted down to the floor next to the assembly line.

What remains is all the weird and awkward automation-resistant tasks where "just get a human to do it" is still easier and cheaper than redesigning everything to maybe get old school automation to handle them.

This is the kind of niche humanoid robots are currently aiming at. It's no coincidence that at least 3 companies trying to develop humanoid robots have ties to vehicle manufacturers.

Makes sense - but I'm still not clear on why it would need to be humanoid in form-factor or indeed self-contained/autonomous and not a more flexible, mobile, multipurpose robot-arm-like-thing?

Like is there any particular reason for it to be about 6' tall with exactly two 3' long, three-jointed arms rather than any of the other possible permutations for those things?

		You want robots that can do tasks humans can do but robot arms can't - which has a way of driving the design decisions. The more you move towards "flexible, mobile, multipurpose", the more you move towards the humanoid frames. Just look up how vehicle interior assembly is performed now. Look at all the things that are still done by humans - all the different assembly stations, all the loading and unloading, all the installation operations, all the panels and wiring harnesses and plugs and bolts. Then try to come up with a robot frame that would do all of it - every single operation that's currently done by a human - while being significantly less complex than a humanoid frame. The design space constraints would choke the life out of you.
