So you're paying someone to operate your robot on top of the cost of the robot?

I'm very skeptical, even if this technology worked flawlessly, that this would scale towards a profitable business. I understand that not every robot would require 24x7 human assistance, but still - this is a very optimistic business model.

Robotics has always been in competition with minimum wage labor. How long could you hire a maid before making a return on the cost of the robot? And that's assuming the robot isn't worse, which it is pretty much guaranteed to be.
