Functional safety product development for autonomous mobile robots
summary
A functional safety process maps HARA-derived safety functions to design, test and operations and is already applied to three Amazon AMR products; the team claims 600,000 robots of one chassis run globally. They build an AWS-hosted risk assessment tool with live collaboration, voting and adjudication to calibrate hazards across projects, plus a robotic-arm sensor test lab using a standardized leg test object and design-of-experiments screening to cut test cases and auto-generate assessor reports, reducing years of manual reporting to roughly a year.
