This legislation mandates the Director of the National Institute of Standards and Technology (NIST) to create a working group focused on the compound risks of artificial intelligence (AI) physical systems. The group's primary objective is to foster coordination among relevant stakeholders concerning the evolving risk landscape due to concurrent advancements in AI technologies, sensor and actuator/robotic technologies, and modeling/simulation tools. Membership will be diverse, drawing from industry, academia, civil society organizations, and other subject-matter experts in areas like cybersecurity and critical infrastructure security. The Working Group is tasked with identifying plausible pathways for physical safety and security concerns, engaging in technical discussions to develop best practices, and recommending analytical tools or guidelines for assessing these risks. It will also identify voluntary best practices for the responsible development and deployment of AI physical systems, aligning its work with existing NIST standards development activities. All activities are designed to be transparent, consultative, and nonregulatory, with an initial report due within 540 days and subsequent updates every two years, all made publicly available.
