What is a public mobile robot (PMR)?

A PMR is an unmanned mobile robot — on wheels or legs — that operates at pedestrian speeds in public spaces such as sidewalks, footpaths, bikeways, roadways, malls, airports, hospitals, parks, etc. 

Electric and efficient, PMRs perform tasks such as delivery, maintenance, or security. They can be teleoperated or automated and can be integrated with electric goods vans and secure locker systems.

Our blog, “Defining PMRs”,  provides a more detailed overview of PMRs in context of ISO 4448.


“Are we doing justice to sidewalk robots?” views PMRs through the lens of emerging legislation in the USA.

What is a public mobile robot (PMR)?

The international  standards for PMRs (ISO DTS 4448), are still evolving and targeted for completion in 2025. As the originator and global project leader of the ISO 4448 series, URF has the unique ability to offer our members a sneak peek to help them anticipate the specific impacts of PMRs on their cites and its people. View the six pillars of ISO 4448 (PDF).

In addition, URF allows its members to input to the evolving standards, potentially changing how PMRs are integrated in their cities. See Membership benefits.
