At this year’s Global Industrie, KUKA is showcasing its new KR C5-2 robot controller, a full year ahead of the European Union’s January 2027 deadline for the new Machinery Regulation (EU 2023/1230). This proactive move comes at a time when digital threats and geopolitical tensions are reshaping industrial cybersecurity, compelling the sector to prioritize resilience.
A Controller Built for the Future
The KR C5-2 is not just an upgrade, it’s a complete rethink of industrial robot control. While the exterior remains familiar, the interior features a new motherboard and a Linux-based operating system, replacing legacy architectures vulnerable to cyber intrusions.
“With the current geopolitical climate, securing industrial systems is no longer optional,” explains Mickael Gremy, Technical Manager at KUKA France. “The KR C5-2 locks down access to system files, encrypts critical operations with 256-bit keys, and ensures only authorized personnel can interact with core functions.”

Why Cybersecurity Matters Now
The stakes are high: hacked robots can halt production, damage equipment, or, worse, endanger human lives. The new EU Machinery Regulation mandates that all machinery, including robots, must be protected against cyber threats, a response to the growing convergence of IT and operational technology (OT) in Industry 4.0.
“Cybersecurity is now a legal requirement for CE marking,” notes Gremy. “Our AMRs were already compliant. Our controller now meets these standards today, so our customers are ready for tomorrow.”
Key Innovations of the KR C5-2
The KR C5-2 introduces a suite of features designed to enhance security, efficiency, and ease of use:
Full Compatibility, Zero Disruption
The KR C5-2 ensures that existing robot programs remain 100% compatible with the new system. As Mickael Gremy explains,
“The programming language is exactly the same. You can copy and paste your programs directly into the new system without any issues.”
This seamless transition guarantees no downtime or need for operator retraining, making the upgrade process smooth and efficient.
Automatic Updates
This is a major innovation: software updates are no longer dependent on KUKA engineers.The KR C5-2 introduces a user-friendly, app-store-like interface where updates are automatically suggested and easily installed.
“The client will have a cockpit where they can access all applications and updates,” says Gremy. “It’s as simple as downloading an update on your smartphone. Users can install new features or security patches directly from their computer.”
Physical and Digital Safeguards
Security is at the core of the KR C5-2’s design. USB ports and external access points are locked down to prevent unauthorized access or data breaches.
“Even if someone plugs in a USB drive with malicious software, it won’t be able to infect the system,” Gremy emphasizes. “The system files are encrypted and protected by a 256-bit key, ensuring that only authorized personnel can interact with critical functions.”
He says that even KUKA’s own teams have limited access. As a technical manager Mickael Gremy has read-only access and can’t make changes.
“Everything is locked down. In my view, it’s impossible for anyone to tamper with the system.”
AI-Ready Architecture
The KR C5-2 is built to support the future of automation, including advanced simulation, virtual commissioning, and AI integration, all within a unified and secure environment.
“Now, everything is integrated into one solution,” Gremy notes. “Basic licenses for 3D simulation and virtual commissioning are now free, making it easier for customers to adopt these technologies without additional costs.”
This integration not only enhances productivity but also ensures that all operations are aligned with the latest cybersecurity standards.
Beyond Europe: A Global Standard
While the KR C5-2 is designed to comply with EU regulations, its robust security features are attracting interest worldwide.
“Countries outside the EU see the value in adopting European-level protections,” says Gremy. “In the U.S., for example, manufacturers are already aligning with these standards to future-proof their operations.”
As of September 2026, KUKA’s catalog will only feature products compliant with this new directive.
