San Francisco restricts the use of delivery robots on its sidewalks

Companies that are testing delivery robots hit a stumbling block in San Francisco this week. The city's Board of Supervisors voted to require permits for any autonomous delivery devices, restricting them to specific (and less-crowded) areas of the city. Additionally, these robots aren't allowed to make actual deliveries -- they are only allowed to be used for testing purposes. This restriction doesn't apply to delivery drones; the San Francisco Board of Supervisors only has jurisdiction over the sidewalks. Complaints were first brought by a group called Walk San Francisco, which campaigns for the safety of pedestrians.
