Sidewalk delivery, calling for help less.

Real streets from OpenStreetMap — Teheran-ro's north side, Nonhyeon-ro and the back streets between them — with a lunch crowd, traffic and walk signals that act on their own. A delivery robot takes orders from a small hub to eight doors and back, on sidewalks where there are some and at the edge of the back streets where there are none. Every second System 1 chooses its manoeuvre from what its four cameras and lidar find; it calls the remote operator only when it cannot go on by itself, and the page counts every call.
