The average American drives 45,000 miles in three years, but a car operated 20⁄7 (like your robot) would accumulate about a million miles in that timeframe. Probably it would go through 2 engines and 3 transmissions if it could even be kept on the road. All things being equal it would need 22x as much maintenance than the average of the US fleet, so probably more like 220% of the capital cost.
A really nice printer/photocopier-combo costs about $10,000 like your robot, and is built from of motors, cameras, and computers just like your robot. While it’s mature technology and built to generally high quality standards, if you try running copies 24⁄7 you will quickly be on a first-name basis with local Kyocera guy.
I feel that it is an overly optimistic take on the state of robotics, particularly the degree of human maintenance that equipment like this requires, how little of it is produced today, and how long it takes to bring new manufacturing on-line considering the deep supply chain needed. The robots described are not the robots of 2027, or even 2127. They are the robots from a long time ago in a galaxy far, far away.
