I stopped in Columbus at the Wexner Center for the Arts on my way west, and found numerous six-wheeled robots tootling around the OSU campus. A robot seemed to manage crossing a driveway (into a parking deck, for instance) just fine, but I had the uncanny feeling that it waited for me to start to cross, that being a signal that it was safe to move. The robot’s cargo bay was about the size of a backpack, but shaped more like a little bathtub.
What were these automata delivering? Library books, mayhaps? Nope, it’s food. It’s always food.
