Before deploying a single robot, map out the layout. Identify "blind spots," narrow corridors, intersections with heavy pedestrian foot traffic, and manual forklift crossing points. Step 2: Define and Measure Safety Zones
ISO 3691-4 governs not just the individual vehicle, but the environment, control systems, and infrastructure where the trucks operate. Key Pillars of ISO 3691-4 Compliance
The standard specifies required friction coefficient (µ ≥ 0.5 for emergency braking). Oily or dusty floors void your compliance. See Annex D – "Environmental conditions."
It is the primary international standard that specifies safety requirements for:

The full title of the standard is:
ISO 3691-4 treats the AGV or AMR not just as an isolated machine, but as an entire interacting with a fluid environment. The standard breaks its requirements down into three main pillars: 1. The Machine Design (The Truck)
, covering systems like Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs). AGV Network
Areas with high risk of entrapment or collision where personnel access is forbidden during operation, often secured by physical fencing or light curtains. Before deploying a single robot, map out the layout
A driverless truck must remain stable under all operating conditions. The standard mandates:
Unlike some older safety standards that prescribe specific technical solutions, ISO 3691‑4 follows a . It draws heavily on the principles of ISO 12100 (general machinery safety) and requires manufacturers to conduct formal hazard identification and risk assessment as a foundational step before any safety measure is specified. This approach is more flexible and encourages innovation, as it leaves room for designers to propose novel protective measures provided those measures achieve the required level of safety.
In most countries, you can purchase the standard more conveniently from your national standards body. These organisations typically offer PDF downloads, often with local pricing in the national currency. Examples include:
