Run the Reprogrammable Test
ISO 8373:2021 supplies the robotics vocabulary the industry works from, and the International Federation of Robotics counts industrial robots as automatically controlled, reprogrammable, multipurpose manipulators. Each of those words is doing real work.
The Bot Scout reprogrammable test applies them in order: is the machine automatically controlled, can it be reprogrammed for a different task without being rebuilt, and is it multipurpose rather than dedicated to one operation. A machine that fails any of the three is production equipment, not an industrial robot, whatever the sales sheet calls it.
This is not pedantry about vocabulary. The classification determines which standards apply, which safety assessment is required, and which vendor category should be quoting the job. Getting it wrong at the specification stage produces a quote that cannot be compared with anything.
| Machine | Reprogrammable and multipurpose | Usual classification | Governing safety approach |
|---|---|---|---|
| Six-axis arm in a fenced cell | Yes | Industrial robot | Application risk assessment with guarding |
| Collaborative arm at a shared station | Yes | Industrial robot used collaboratively | Assessment including contact and tool hazards |
| Autonomous mobile robot | Yes, for transport tasks | Mobile robot, often counted separately | Route, traffic, and pedestrian assessment |
| CNC machine or dedicated press | No | Machine tool, not a robot | Machine-specific safeguarding |
| Hard-tooled pick-and-place | No | Fixed automation | Fixed-guarding approach |
Why the Classification Changes the Project
A collaborative robot is still an industrial robot; what changes is how the application is assessed. ISO 10218-1:2025 sets safety requirements for industrial robots and ISO/TS 15066:2016 supplements the series for collaborative systems and their work environments.
OSHA notes that many robot incidents occur during non-routine work such as programming, setup, adjustment, testing, and maintenance rather than during normal production. That is the argument for assessing the whole application, including the people who service it.
The practical consequence for buyers is that "cobot" is not a safety category you can purchase your way into. The full framework is in the cobot guide, and the workflow view is in the industrial robots hub.
How to Specify Before You Compare Quotes
Write the task, payload, reach, cycle time, repeatability, quality target, and changeover requirement before contacting vendors. Those figures let two proposals from different categories be compared on the same terms.
Builders including Universal Robots, ABB Robotics, and FANUC publish product families across these categories, so the same supplier may propose more than one classification for a single job.
The specification detail most often left out is the exception: what the cell does with a part that arrives wrong. A quote that assumes every part is in tolerance is quoting a demonstration rather than a production cell.

- Apply the three ISO criteria before accepting a vendor's category label.
- Specify task, payload, reach, cycle, repeatability, and changeover in writing.
- Require an application-specific safety assessment, not a product safety claim.
- Define what happens to an out-of-tolerance part before comparing prices.
- Include programming, setup, and maintenance access in the risk assessment.
Bottom Line
An industrial robot is defined by automatic control, reprogrammability, and multipurpose use. Classify the machine correctly and the applicable standards, vendor category, and safety obligations follow.
Apply the three ISO criteria to the machine in front of you before accepting any vendor's category label.
FAQs
What is the definition of an industrial robot?
Industry practice follows the ISO 8373 vocabulary and IFR counting: an automatically controlled, reprogrammable, multipurpose manipulator. A machine that cannot be reprogrammed for a different task is fixed automation instead.
Is a cobot an industrial robot?
Yes. A collaborative robot is an industrial robot used in a collaborative application. What changes is the safety assessment, which must cover contact, tooling, and the people who share the space.
Is a CNC machine a robot?
No. A CNC machine is a machine tool dedicated to a class of operations. It is not multipurpose in the sense the robot definition requires, and it is safeguarded under a machine-specific approach.
Why does the classification matter for a buyer?
It determines which standards apply, which safety assessment is required, and which vendor category should quote the work. Misclassifying the machine produces quotes that cannot be compared.
