ANSI/A3 R15.08-3-2026, the third and final section of the Association for Advancing Automation's industrial mobile robot safety standard, has gone on sale in Ann Arbor, Michigan, completing a three-part framework that spans the operating life of a mobile robot system.

The new document focuses on what happens after an industrial mobile robot (IMR) goes into service. It codifies the responsibilities of manufacturers, integrators and end users during day-to-day operation: risk assessment, management of change, employee training, and periodic reviews and inspections.

What does Part 3 cover?

Part 3 addresses four operational responsibilities for users. The standard spells out procedures for ongoing risk assessment whenever a robot's application, equipment or operating environment shifts, and prescribes how often those assessments should be repeated.

It also requires a formal management-of-change process whenever a user modifies the robot, its task or the surrounding work cell. Employee training programs must match the robot's current task rather than its original deployment configuration. A schedule of periodic reviews and inspections keeps residual risk within acceptable limits.

How does the three-part framework fit together?

A3 built R15.08 as a lifecycle document. Part 1 covers the mobile robot itself: design, construction and the safety features built into the unit. Part 2 covers IMR systems and applications, the integration layer where the machine meets its assigned task.

Part 3 closes the loop on operational life. Together, the three sections give manufacturers, integrators and operators a single reference for evaluating safety at each stage, from design review through routine maintenance.

Why does the post-deployment section matter?

Industrial mobile robots rarely stay static on the plant floor. Routes change, payloads change, attachments are added, and workflows are reconfigured. Most users treat deployment as a one-time event.

The standard asks them to manage those changes deliberately, with documented reviews and trained personnel rather than informal adjustments to a robot's task or environment.

Where does the framework sit?

The R15.08 series addresses a category of equipment that has moved from pilot projects into routine factory use in recent years. A3 wrote it to give U.S. users a coherent set of safety practices aligned with the ANSI consensus process, in a format that integrators can reference in contracts and end users can audit against.

With Part 3 now final, integrators and end users have a single document to cite when a procurement specification asks how post-deployment safety will be maintained. A3 offers the Part 3 document on its own and a three-part bundle containing all sections of R15.08.

What to watch next

The 2026 release date positions the standard for adoption in the next round of integrator specifications and corporate safety audits. Plant safety officers and robotics integrators become the primary audience for Part 3 training through 2026, and A3 is likely to schedule industry briefings around the new document.

Procurement teams writing mobile robot specifications this year should expect to see explicit references to R15.08-3 in vendor documentation.
