What is Physical AI Safety?

Physical AI Safety is the discipline of designing and assuring the safety of physical AI systems — robots, autonomous vehicles, and other machine-learning-driven machines that act in the physical world — at assurance levels comparable to established functional safety. It bridges three traditions, AI Safety, Functional Safety, and Robot Safety, none of which, alone, addresses the failure modes that arise when machine-learning components drive physical actuators.

Physical AI Safety by the numbers

The gap is measurable in public data. Every figure below is sourced.

Regulation

Who checks what the AI commands before the motor moves?

Regulation (EU) 2026/1744 obliges the Commission to add AI health and safety requirements to Annex III of the Machinery Regulation, and those delegated acts shall apply by 2 August 2028. That is 560 days after the Machinery Regulation's own 20 January 2027 start date. Annex III has no AI section today, and a new Article 20(10) already presumes conformity with it.

Regulation

After the attack: five years of security updates, as a rule. The EU line for connected physical AI.

Part 11 of 12. From 11 December 2027, the Cyber Resilience Act sets a support period of at least five years, unless the product is expected in use for less. Security updates must be free and, where feasible, kept apart from new features. In the US, only a voluntary consumer label asks makers to disclose a support period.

Regulation

After the attack: who pays? Europe's answer changes in December.

Part 10 of 12. The new EU Product Liability Directive treats software as a product, counts safety-relevant cybersecurity requirements when judging a defect, and keeps the maker liable for a missing safety update within its control. It covers products placed on the market or put into service after 8 December 2026. In the US, liability still runs through state tort law, and courts split on whether software is a product.
