An AGV manufacturer should design and validate its vehicles against the safety requirements applicable to the target market, vehicle type, operating environment, and control architecture. In practice, I recommend assessing ISO 3691-4 for driverless industrial trucks, ISO 12100 for machinery risk assessment, IEC 60204-1 for electrical equipment, and ISO 13849-1 or IEC 62061 for safety-related control systems. Depending on the destination market, additional requirements such as ANSI B56.5, electromagnetic compatibility rules, machine guarding regulations, and local product laws may also apply.

At Zhijieyou, I treat compliance as a complete engineering process rather than a label placed on a finished AGV. The manufacturer should be able to explain its risk assessment, protective functions, stopping behavior, electrical design, software safeguards, inspection records, and technical documentation. Buyers should also verify whether the proposed compliance scope covers the entire AGV system, including chargers, sensors, traffic controls, and interfaces with surrounding machinery.
ISO 3691-4 is one of the most important references for automated guided vehicles and other driverless industrial trucks. It addresses hazards related to autonomous movement, operating zones, protective devices, control systems, docking, loading, and interactions with people. Its relevance depends on the vehicle classification and intended use, so a manufacturer should explain how the standard has been applied to the specific AGV design.
This standard does not replace a site-specific risk assessment. An AGV that is safe in a controlled warehouse may require different protective measures in a mixed-use factory with pedestrians, forklifts, ramps, narrow aisles, or frequent loading operations. I therefore ask customers to provide layout drawings, traffic rules, payload information, floor conditions, and operating speeds before finalizing the safety design.
ISO 12100 provides a structured approach for identifying hazards, estimating risks, reducing risks, and documenting the remaining risks. A responsible manufacturer should examine mechanical crushing, shearing, impact, unexpected movement, battery hazards, electrical energy, maintenance access, and foreseeable misuse. The process should continue throughout design changes, not only during final inspection.
The risk assessment should lead to practical protective measures. These may include physical design features, safety-rated sensors, emergency stop devices, reduced-speed modes, warning indicators, controlled access, and clear operating instructions. I consider a documented risk-reduction process more useful than a general statement that an AGV is “safe.”
IEC 60204-1 is a key reference for the electrical equipment of machinery. It covers topics such as electrical enclosures, protective bonding, overcurrent protection, control circuits, wiring identification, isolation, and documentation. For a battery-powered AGV, the review should also consider charging equipment, battery protection, connector design, energy isolation, and maintenance procedures.
Electrical requirements vary according to the battery chemistry, charging method, voltage level, and local regulations. For example, a project may use a 24 V DC control system or a 48 V DC traction system, but these values are design choices rather than universal AGV requirements. I recommend that buyers request electrical schematics, component specifications, protection methods, and inspection criteria before approving production.
AGV safety depends heavily on control functions such as emergency stopping, protective-field monitoring, speed limitation, direction control, and safe restart. ISO 13849-1 and IEC 62061 provide recognized frameworks for designing and validating safety-related control systems. The applicable method depends on the architecture, technology, risk level, and project requirements.
A manufacturer should define each safety function and its required performance level or safety integrity level where applicable. The evidence may include circuit architecture, component suitability, diagnostic coverage, fault analysis, validation testing, and proof that a single fault does not create an unacceptable hazard. I do not treat a standard programmable controller as automatically equivalent to a safety-rated controller.
An AGV should use suitable sensing technology for its environment, such as safety laser scanners, safety-rated bumpers, scanners, or other protective devices selected through risk assessment. The protective field must account for vehicle speed, braking performance, sensor response time, load condition, floor quality, and the possibility of people approaching from different directions. A sensor should not be judged only by its detection range.
The manufacturer should document how protective fields are configured, tested, and adjusted. I also recommend checking whether the AGV can distinguish between normal operating conditions and blocked paths without creating unsafe automatic behavior. A vehicle that stops reliably but cannot restart safely may still create operational pressure for workers to bypass procedures.

Emergency stop devices should be easy to access and integrated into a broader stop strategy. The design should explain what happens to propulsion, steering, lifting mechanisms, conveyors, and connected equipment when an emergency stop is activated. After a stop, restart should require a deliberate action and should not cause unexpected movement.
Stopping performance must be verified under realistic conditions, including maximum payload, floor variations, battery conditions, and normal operating speed. For example, a buyer may specify a maximum speed of 1.0 m/s for a particular route, but the required stopping distance must be calculated and validated rather than assumed. I advise requesting recorded test conditions and acceptance criteria instead of relying on a single nominal stopping value.
AGV safety extends beyond the vehicle itself. The system may need traffic rules, intersection control, warning lights, audible signals, speed zones, pedestrian crossings, restricted areas, and communication with doors or production equipment. These measures should be designed together because a technically compliant vehicle can still create risks if the workplace layout is poorly controlled.
Clear status indicators are also important. Operators should be able to understand whether the AGV is running, waiting, charging, blocked, in manual mode, or reporting a fault. Instructions should cover normal operation, recovery from obstruction, battery handling, cleaning, maintenance, and isolation of hazardous energy.
Electromagnetic compatibility should be evaluated when AGVs operate near robots, welders, wireless networks, sensors, medical equipment, or process-control systems. The manufacturer should identify the applicable EMC requirements and verify that communication or control functions do not become unreliable under expected interference conditions. Battery and charger safety should be addressed as part of the complete installation, not treated as a separate purchasing detail.
Charging arrangements may include automatic contacts, inductive charging, opportunity charging, or manual connection. Each option introduces different risks related to alignment, exposed electrical parts, heat, ventilation, access control, and fire response. If the AGV operates for an 8-hour shift, I would ask the supplier to explain the planned charging cycle, battery capacity, thermal protection, and safe behavior when the battery reaches a defined low-charge condition.
A professional AGV manufacturer should provide documentation that allows the buyer to understand, operate, maintain, and inspect the system. Typical documents include user manuals, installation requirements, electrical diagrams, spare-parts information, risk-assessment records, safety-function descriptions, software or parameter-control procedures, and test records. The final package should match the delivered configuration.
Buyers should be cautious when a supplier provides only a product brochure or a generic certificate. A certificate may apply to a component, model family, or specific market and may not cover the complete AGV installation. I recommend asking who performed the assessment, which model and configuration were evaluated, which standards were used, and what exclusions or operating limits apply.
Formal compliance is necessary, but it is not the only supplier-selection factor. I also evaluate whether the manufacturer can adapt protective fields to the site, integrate with doors and conveyors, support commissioning, and explain limitations honestly. A supplier that identifies an unresolved risk before shipment is more valuable than one that promises universal suitability without evidence.
Zhijieyou supports B2B AGV projects by discussing application requirements, vehicle configuration, navigation method, payload, route conditions, charging arrangements, and safety interfaces during the quotation process. Our role is to help customers define a practical technical scope and identify the documentation and testing needed for their project. Final conformity remains dependent on the agreed design, installation, local rules, and operating conditions.
An AGV manufacturer should provide more than a vehicle that moves autonomously. It should demonstrate a standards-based risk assessment, suitable protective devices, validated safety-related controls, controlled stopping and restarting, safe electrical and charging arrangements, clear documentation, and a commissioning plan matched to the operating site. The exact standards depend on the country, AGV type, workplace, and integration scope.
My recommended next step is to prepare an application brief covering payload, maximum speed, route layout, pedestrian interaction, floor conditions, charging method, work schedule, connected equipment, and destination market. Send these requirements to Zhijieyou for a technical review and quotation discussion. We can then identify the applicable safety framework, clarify project limitations, and define the evidence and acceptance tests required before delivery.
