Industrial mobile robots are becoming an important part of modern manufacturing, warehousing, and material handling. However, as factories introduce robots from different manufacturers, communication between different systems can become a major challenge. A new international standard, ISO 21423:2026, aims to address this issue by establishing common communication and interoperability requirements for industrial mobile robots (IMRs).
Announced by the Association for Advancing Automation (A3), the standard provides a common framework that allows mobile robots from different suppliers to exchange information and coordinate their operations within the same industrial facility. This development could make multi-vendor automation systems easier to deploy, manage, and expand.
What Is ISO 21423:2026?
Developed under ISO Technical Committee 299, ISO 21423:2026, titled Robotics – Industrial Mobile Robots – Communications and Interoperability, defines how industrial mobile robots, fleet management systems, and other equipment communicate with one another.
The standard establishes common requirements for exchanging operational information and requesting actions. This includes key data such as:
- Robot location and movement speed.
- Travel direction and current operating condition.
- Assigned tasks and operational availability.
- Information exchanged between robots and fleet management systems.
By providing a common communication framework, ISO 21423 aims to reduce dependence on manufacturer-specific communication arrangements. As a result, industrial users can have a clearer path toward integrating robots from different suppliers into one coordinated system.
Why Interoperability Matters in Industrial Automation
In many factories and warehouses, mobile robots are supplied by different manufacturers to meet specific operational requirements. One supplier may provide robots for pallet transportation, while another supplies units for material delivery or internal logistics.
Although these robots may perform their individual tasks effectively, coordinating their movements can be difficult when their communication systems are not compatible.
Without consistent information exchange, robots may encounter conflicting routes, inefficient traffic arrangements, or delays when sharing working areas. These issues can affect equipment availability and reduce the overall performance of automated material handling systems.
ISO 21423 addresses this challenge by creating a shared basis for communication. Robots can exchange information about their positions, movements, tasks, and availability, helping fleet management systems coordinate operations more effectively.
In practical terms, this means industrial facilities may have greater flexibility when selecting equipment and expanding existing automation systems.
How the Standard Supports Robot-to-Robot Communication
One of the important aspects of ISO 21423 is its focus on information exchange between different mobile robot systems.
For example, when several robots operate in the same warehouse, their movements need to be coordinated to avoid traffic conflicts. By sharing location, speed, direction, and operating status, the systems involved can make better-informed decisions about movement and task allocation.
The standard also addresses communication between mobile robots and external industrial equipment, including:
- Machines and production equipment serviced by robots.
- Enterprise Resource Planning (ERP) systems.
- Industrial building equipment, such as elevators and automated doors.
- Alarm systems and other facility infrastructure.
- Mobile devices used by personnel working alongside robots.
This broader scope is particularly relevant to facilities where mobile robots operate as part of a connected production and logistics environment rather than as isolated machines.
Potential Benefits for Manufacturers and End Users
The introduction of ISO 21423 could bring several practical benefits to industrial automation projects.
1. Greater Flexibility in Equipment Selection
Manufacturers and system integrators may have more freedom to select mobile robots based on payload, operating environment, navigation capabilities, and application requirements instead of relying entirely on one supplier's ecosystem.
2. More Efficient Fleet Coordination
A common communication framework can help different robot systems exchange operational information. This may reduce unnecessary route conflicts and improve coordination across shared working areas.
3. Easier Expansion of Existing Systems
When a facility needs additional mobile robots, interoperability can make it easier to introduce equipment from another manufacturer. This is especially valuable for businesses expanding automation in stages.
4. Increased Market Competition
A common international standard may reduce some integration barriers for manufacturers entering multi-vendor automation projects. Greater competition could encourage suppliers to improve their products and develop more flexible solutions.
5. Wider International Adoption
As an ISO standard, ISO 21423 provides an internationally recognized reference for communication and interoperability. This can support automation projects across different countries and industrial markets.
Engineering Perspective: What ISO 21423 Could Mean for the Future of Mobile Robotics
From an industrial automation engineering perspective, the value of ISO 21423 goes beyond establishing another communication standard. Its real importance lies in addressing a long-standing problem in multi-vendor automation: the difficulty of making independently developed equipment work together as one coordinated system.
In actual industrial projects, selecting a mobile robot is not simply a matter of comparing payload capacity, travel speed, or battery life. Engineers also need to consider fleet management, production scheduling, traffic control, machine interfaces, and communication with existing infrastructure.
A common interoperability framework could simplify part of this engineering work and give end users more control over their automation architecture.
However, standardization does not automatically guarantee plug-and-play compatibility. Manufacturers still need to implement the requirements correctly, and system integrators must verify communication behavior, task coordination, safety functions, and performance under real operating conditions.
It is also important to distinguish communication interoperability from functional safety. ISO 21423 focuses on communication and interoperability; it should not be treated as a replacement for applicable robot safety standards or a complete safety solution for mixed robot fleets.
For industrial users, the most practical approach is to consider interoperability during the initial system design rather than waiting until equipment from multiple suppliers needs to be connected.
ISO 21423:2026 Availability and Industry Background
The Association for Advancing Automation (A3) announced the publication of ISO 21423:2026. The organization has been involved in developing automation technologies and supporting industry standards across the global robotics sector.
The standard is available through the A3 online store at the following prices:
- A3 members: $320
- Non-members: $373
A3 represents more than 1,500 manufacturers, component suppliers, system integrators, end users, academic institutions, research organizations, and consulting firms.
The publication of ISO 21423 marks an important development in industrial mobile robot standardization. As multi-vendor robot fleets become more common, consistent communication will play an increasingly important role in building flexible and scalable automation systems.
Ultimately, the success of this standard will depend on how widely robot manufacturers adopt it and how effectively system integrators apply it in real industrial environments. Nevertheless, it represents a meaningful step toward a more open and connected mobile robotics ecosystem.
