This will be a very serious question one day. Robots might be numerous and annoying. Their owners might steer them into places where they aren’t welcome. Or they might just go adventuring on their own. Criminals might hijack them.

Robots will need clear, official, enforced guidelines for where they can and cannot go.

I propose a continuous zone (they need to be able to get from A to B) which is a public access area for all robots. Beyond that, anywhere outside of the zone will require permission for entry.

The best way of running this is a universal, wirelessly-connected mapping system with focus on permission-based access.
