Evolution of Safety Requirements in Industrial Robotics: Comparative Analysis of ISO 10218-1/2 (2011 vs. 2025) and Integration of ISO/TS 15066
This paper presents a comparative analysis of the ISO 10218:2011 and 2025 standards, highlighting the evolution of industrial robotics safety requirements through the integration of cybersecurity measures, expanded functional safety classifications, and the normative incorporation of ISO/TS 15066 to establish a comprehensive framework for modern robotic systems.

Imagine the world of industrial robots as a giant, high-speed construction site. For years, the rulebook for keeping workers safe on this site was written in 2011. It was a good rulebook, but it was written for a time when robots were like giant, caged beasts: they worked alone, and humans stayed far away.
Now, the rulebook has been completely rewritten for 2025. The authors of this paper, a team of safety engineers from the Czech Republic, have analyzed the old rules versus the new ones. They found that the new rules aren't just a few tweaks; they are a total makeover to handle a world where robots and humans work side-by-side, and where robots are connected to the internet.
Here is the breakdown of what changed, explained simply:
1. The "Cage" is Gone, But the Rules are Tighter
In the old days (2011), the rulebook focused mostly on the robot itself—making sure its metal arms were strong and its emergency stop buttons worked. It treated the robot like a "partially finished machine" that someone else would finish.
The new 2025 rulebook realizes that the robot is no longer just a machine; it's part of a complex dance with humans.
- The Analogy: Think of the old rules as a manual for building a safe car engine. The new rules are a manual for driving that car in a busy city with pedestrians, while also making sure the car's GPS system can't be hacked by a hacker.
- The Change: The new rules now cover the entire "application" (the robot + the workpiece + the task), not just the robot. They also explicitly say: "If you are building a robot for a hospital or a military tank, these rules don't apply." They are strictly for factory floors.
2. The "Cyber-Door" Must Be Locked
The biggest new addition is Cybersecurity. In 2011, the rulebook didn't even mention the internet. In 2025, it's a major chapter.
- The Analogy: Imagine a bank vault. In 2011, the rules were about making the steel door thick. In 2025, the rules also say, "You must also lock the Wi-Fi password, or a thief could walk in through the digital window and open the door from their phone."
- The Change: Manufacturers now have to prove their robots can't be hacked. They need to check for "cyber threats," use encrypted messages, and make sure no one can sneak in and change the robot's safety settings remotely.
3. The "Collaborative" Shift: From "Robot" to "Team"
For a long time, if a robot worked with a human, it was a special, experimental thing called a "Collaborative Robot." The 2011 rules barely touched on this. A separate, smaller guide (ISO/TS 15066) existed just for this.
The 2025 rulebook swallows that separate guide whole.
- The Analogy: In 2011, "collaboration" was like a special VIP club with its own entry fee. In 2025, collaboration is just a normal part of the job. The rulebook stops calling it a "Collaborative Robot" and starts calling it a "Collaborative Application."
- The Change: It's not about the robot being special; it's about how the task is done. If a human and robot work together, the safety rules now demand specific measurements of how hard the robot can hit a human (force and pressure) and how fast it must stop. These rules are no longer optional; they are mandatory.
4. The "Digital Twin" and the New Math
The new rules require much more detailed math and testing.
- The Analogy: In 2011, if you wanted to check if a robot was safe, you might just push it to see if it stopped. In 2025, you have to measure exactly how much force it exerts on a human body part (like a finger or a knee) and prove it won't cause pain or injury.
- The Change: The paper notes that this requires new tools. Integrators (the people who set up the robots) now need to measure "biomechanical limits." It's like moving from a simple ruler to a high-tech medical scanner to ensure safety. The paper suggests that in the future, computer simulations (digital twins) might help do this math before the robot is even built, saving time and money.
5. The "Instruction Manual" Overhaul
The rules for how to write the user manual have changed drastically.
- The Analogy: The old manual was like a quick-start guide: "Press this button to start." The new manual is like a complete medical dossier for the robot. It must list every single safety feature, its software settings, and exactly what to do if the robot gets hacked.
- The Change: The manuals must now follow a strict international format. They must include details about cybersecurity (how to update the firewall) and exactly how the robot behaves in an emergency. If the robot is too small to fit all this text on a sticker, you can now use a QR code to link to the digital manual.
Summary: What Does This Mean?
The authors conclude that the 2025 update is a generational overhaul.
- It's not just a patch: It's a new foundation.
- It's global: It's designed to work everywhere, not just in Europe.
- It's realistic: It acknowledges that robots are now connected, collaborative, and complex.
While the new rules mean more work for companies (more testing, more paperwork, more cybersecurity checks), the authors argue that this is actually good news. It turns safety standards from a simple "checklist" into a comprehensive engineering guide. This ensures that as robots become more human-like in their interactions, they remain safe for the humans they work with. The paper suggests that companies that were already preparing for these changes won't be shocked; they will just be ready to follow the new, clearer map.
