Abstract
Physical AI deployments — humanoid robots, autonomous mobile robots, surgical systems, autonomous vehicles — are scaling faster than the safety vocabulary used to describe them. Safety claims across organizations are not comparable. Adjacent fields solved this problem with maturity models: CMMI for software process, AI Safety Levels (ASL) for AI safety posture, ISO/IEC 33001 for process assessment, PCI DSS for payment-industry security. Physical AI lacks an equivalent. This paper proposes the Physical AI Safety Maturity Model (PAS-MM) , a five-level classification system: Ad-hoc, Documented, Compliant, Certified, and Defense-in-depth. Levels are anchored to recognized…
