Get Certified | Turn the Lens Ep54","description":"Werner Kraus leads robotics research at Fraunhofer IPA, where 1,000 engineers work on production systems and the unglamorous infrastructure that makes humanoids commercially viable: standards. Not the headline-grabbing demos, but the 30-40 tests required before a robot can enter a semiconductor clean room. The certification processes that determine if particle emissions from gear grease will contaminate pharmaceuticals. The biomechanical measurements proving that 500 Newtons of collision force is 3x too high for human safety. Standards enable commercialization. Without them, you can't get insurance. You can't satisfy business buyers. You can't scale beyond pilot programs. Werner's team at Fraunhofer IPA does the methodical work of defining what "safe" and "clean" actually mean in measurable terms\u2014then working with ISO committees and robot manufacturers to close the gaps between current performance and certification requirements. I sat down with Werner to explore how clean room certification works across nine ISO classes, why the Unitree G1 currently achieves ISO Class 5 (semiconductor standard), what 500 Newtons of collision force actually means for human safety, and the surprising discovery his team made about data transmission to China when testing cybersecurity. Werner walks through the reality that robots themselves are contamination sources\u2014emitting particles from wear, harboring dirt in crevices, and requiring steel surfaces instead of coatings in pharma environments. He explains why energy efficiency standards matter (the Unitree consumes 280W and requires battery swaps every 100 minutes), how ISO\/TS 15066 sets different force limits for different body regions, and why his team consults with manufacturers on design changes to improve safety ratings rather than simply issuing pass\/fail grades. Clean room certification, collision biomechanics, ISO standards development, cybersecurity testing, energy consumption benchmarking\u2014top concepts covered. But what struck me most was the systematic rigor: not rushing humanoids to market, but methodically defining the thresholds that protect both workers and product integrity. That is a robot future built on engineering discipline rather than hype cycles.

He leads standards development and certification testing for collaborative and humanoid robots, working directly with ISO committees and manufacturers on safety, clean room, and performance requirements. ABOUT THE SHOW Turn the Lens explores the future of work, technology adoption, and the human side of innovation. Hosted by Jeff Frick, the show features in-depth conversations with leaders shaping how we'll work tomorrow. This interview is a collaboration between Turn the Lens and Humanoids Summit, and was conducted at Humanoids Summit SV, Computer History Museum, Mountain View, California, December 2025. Humanoids Summit is organized and hosted by ALM Ventures.
