About

Hiromitsu Kumamoto is a pioneering researcher in the field of human-robot system safety assessment, whose work has made foundational contributions to understanding and mitigating hazards in industrial robotics environments. Working primarily through the 1980s and continuing into recent decades, Kumamoto developed sophisticated methodologies for analyzing accident-causing mechanisms in human-robot interactions, earning recognition through sustained citation of his research across the field. His most influential contributions include the development of Boolean logic models for representing accident-causing mechanisms and the quantification of consecutive failure logic within Fault Tree Analysis (FTA). These tools provided engineers and safety professionals with systematic frameworks to identify overlooked hazards in robotic systems, particularly during vulnerable operational phases such as troubleshooting in automatic modes. His introduction of "Action-Chain-Models" offered a structured approach to enumerating robot-related hazards in unmanned manufacturing environments, demonstrated through realistic case studies involving NC machines and industrial robots. With his most-cited work accumulating 13 citations and a body of research spanning over three decades — culminating in a 2018 review chapter synthesizing his safety methodologies for contemporary human-robot systems — Kumamoto represents a steady and rigorous voice in industrial safety engineering, whose frameworks remain relevant as collaborative robotics continues to evolve.
