I wonder how it avoids pipes stubbed up through the slab, or electrical EMT, etc. or how it avoids mistakes made during the rough-in.
What if the plumber missed a drain or supply by an inch? Guessing the robot doesn't adjust its outline. I.e. if a sewer stub is wrong by a few inches, the wall needs to be moved to fit the toilet, or the slab needs to be busted up and the sewer line relocated.
I suppose if it gets some of this wrong, it'll be obvious, and a human can correct it.
