@dgreene196 it's basically a super-sized Roomba—constantly vacuums our very large floors in a quiet, library way.
@dancohen Very cool. The new children's hospital currently under construction in my neck of the woods will have robots transporting supplies from a central hub to various floors in the building (separate mini elevators for the robots, too). I wondered if they were doing something similar with books and other library media. My first job was putting books away in the local library, and it will be sad (for me) when that's a job humans no longer perform.
