Tunnels, at least in heavily populated areas. They already make pipes that should be big enough. It might require a slight redesign of the bots so that they can "climb the wall" a short distance to pass each other, and maybe extend/retract some bits depending on whether they're inside or out, but my heart would not exactly bleed over the money spent. And they'd be out of sight, out of mind most of the time for the rest of us.
If they are going to put in tunnels, they may as well just put in a pneumatic tube system so the robots wouldn't be needed.
and that'll be a lot cleaner. I won't be ordering my food from things running in open tunnels of big cities, they'll be smelling of piss within a day
Food in the tunnels is how you get even more rats... And what would happen when one breaks inside. What about rotting food spillage.
They obviously need to design cleaning robots and rat-catching robots and repair robots to support the delivery robots. I mean, we could have an entire robot ecology here, living unnoticed under the city streets.
