It's funny how ideas come to you. I was walking down the hall at work one day, and I suddenly
had an image of trash robots. Instead of "dumb" waste baskets, they would be little simple robots - whose only function was to travel (at a pre-set time) to a place in the building where they could be emptied (either by a person or another mechanism) - then they would travel back to where they came from. It would look like the sorcerers apprentice: suddenly, all the waste baskets would start filing out of the offices and rolling down the hall to the dumpster. That's what I imaged one day.
