About

K. Fukaya is a pioneering researcher in the field of passive robotics, with a specific focus on human-robot collaboration for object transportation. His major contributions center on the development and control of passive mobile robots—systems that lack active driving motors and instead rely on servo or MR (magnetorheological) brakes to generate controlled resistance. Fukaya introduced two influential prototypes: the RT Porter and the Passive Robot Porter (PRP), both designed to transport objects in seamless cooperation with a human operator. Through his work, he established impedance-based motion control as a key framework for these passive systems, enabling intuitive and safe physical interaction. His most cited paper, "Transporting an Object by a Passive Mobile Robot with Servo Brakes in Cooperation with a Human" (2009), has garnered 39 citations, with his cumulative work on the PRP and RT Porter accumulating over 70 citations. Fukaya’s research is notable for redefining robot assistance—shifting from active, autonomous machines to safe, compliant partners that empower human effort rather than replace it. His achievements have laid critical groundwork for assistive robotics in logistics, manufacturing, and rehabilitation.
