Future-of-work stuff aside, I’m always confused when I see bipedal robots. Doesn't make any sense unless one is dealing with rough terrain — and there, four or six legs would probably be better. I guess they're cool for Boston Dynamics investor videos.

For floor work, wheels seem the most logical. There is the issue of loading trucks (which I did at UPS for a couple summers), for that I’m thinking maybe a ceiling-mounted arm that could extend the length of the truck?
