• ISO 3691-4:2023 is edition 2, published 2023-06, 74 pages, at stage 90.92, international standard to be revised.
• Its examples of driverless industrial trucks include automated guided vehicle, autonomous mobile robot, bots, automated guided cart, tunnel tugger and under cart.
• It covers trucks with automatic modes, trucks able to carry riders who are neither drivers nor operators, and trucks with additional manual modes.
• The standard sits under ISO technical committee 110 on industrial trucks, not the robotics committee, which is why robot buyers often miss it.

The machine, Workers and bystanders, The AI inside it. Stated means the document you can open below says it; silent means the ledger read the document and it does not.

The machineStated

It is the safety standard a warehouse AMR is actually judged against, covering the truck and its control, guidance and power system.ISO, ISO 3691-4:2023 Industrial trucks, Safety requirements and verification, Part 4: Driverless industrial trucks and their systems, primary source, 1 June 2023.

Workers and bystandersStated

Protective measures around pedestrians in shared aisles are the core of the document.ISO, ISO 3691-4:2023 Industrial trucks, Safety requirements and verification, Part 4: Driverless industrial trucks and their systems, primary source, 1 June 2023.

The AI inside itSilent

Navigation autonomy is treated as a controlled function, and learned perception is not addressed.ISO, ISO 3691-4:2023 Industrial trucks, Safety requirements and verification, Part 4: Driverless industrial trucks and their systems, primary source, 1 June 2023.

If you sell or deploy mobile robots in a warehouse, your standard lives in the industrial trucks committee and not in robotics, and calling your product an autonomous mobile robot does not move it. Check which edition your customer's specification names, because ISO has marked this one for revision and a new edition changes the acceptance tests you will be asked to pass.
