Playing it safe!

Recently, Agile Robots AG received a certificate (No. Z10 116233 0003) from TüV SüD for its "Safety Core for Robot Applications." The assessment attests the development of a software library in accordance with IEC 61508-3, which includes cutting-edge safety functions such as power and force limiting and safe collision detection for industrial and collaborative applications.
The IEC 61508 standard, titled "Functional safety of electrical/electronic/programmable electronic safety-related systems," is widely recognized as the foundation for safety in various industries. It provides guidelines and requirements for the development and implementation of functional safety in complex systems that incorporate electrical, electronic, and programmable electronic components, including industrial and collaborative robots.
By understanding standards such as IEC 61508, ISO 13849, ISO 10218, and being acquainted with the Machinery Directive and other legal product requirements, we can develop a comprehensive understanding of what safety in an industrial environment entails. This understanding goes beyond academic ideas and proofs of concepts and provides crucial and necessary insights into the legal and industry-specific obligations. This builds the foundation for building safe and industrial-grade products.
Building up this knowledge takes time. Just the IEC 61508 standard alone comprises several hundred pages. It took me years, countless hours of training, and fruitful discussions to gain a solid understanding of the topic of machine and functional safety, and I continue to enhance my knowledge every single day.
This is an example that highlights the significance of having a strong and robust network. Throughout the years, I have collaborated with numerous intelligent and knowledgeable people who have been essential in helping me develop a deeper understanding of the subject matter.
