We're at something of a tipping point for helper robots in general, and especially for AGV delivery robots. Futurists envision a digital "smart city" where these robots play an integral part of the on-demand economy, and many cities and businesses are rolling out the welcome mat. Starship Technologies, Effidence, Savioke, Marble and other robotics companies have had their 'bots delivering takeout food, small packages, and flowers for some time, and many prominent retailers are looking to up the ante in the race to solve the perennial last-mile delivery problem of delivering goods direct to your door. The need and timing are right to see these task-driven robots achieve operational feasibility in cities.
On the other hand, some cities have put the brakes on the use of AGV robots for delivery, and are enacting new zoning restrictions, requiring a permit for their operation or requiring that a human handler be present while the robot is in use. Some of this restraint is driven by legitimate public concerns around safety when humans and robots share the sidewalks, but other people simply consider the use of a high-tech robot to make a sandwich delivery as just another unnecessary and unwanted gizmo.
