A washer+dryer is pretty huge already. Seems like it could get some robot arms without changing the form factor dramatically.
That said, I think this is way farther off than anyone thinks. I want to know what the maintenance schedule looks like for robot arms. Looks like a lot of small moving parts. Probably a lot of plastic gears.
In an industrial setting, sure, maintenance is just an expense. But wheels require less maintenance and factories can be designed around the robots.
Plastic gears? I sure hope not!
As I said, maybe earlier in this thread, I've now seen a laundry folding robot work, but I think loading a dishwasher and then putting away dishes is going to come first.
