About

Kazuhiko Otsubo is a pioneering researcher in the field of human-robot collaboration, with a specific focus on developing manipulators for cooperative work in unstructured environments. His foundational work, beginning in the early 1990s, directly addressed the impending labor shortages in aging societies, particularly within the demanding construction and civil engineering sectors. Otsubo’s major contributions lie in the mechanism design and control algorithms for "Man-Robot Cooperation Work-Type Manipulators," a concept that was visionary for its time. He proposed novel solutions for critical safety and stability challenges, such as his "center of gravity control" method for manipulator/vehicle systems, which prevents the robot from tipping over during cooperative tasks. His most cited paper (9 citations) established the core principles of this cooperative manipulator, while his subsequent works refined the control strategies for structurally changeable tasks. By tackling the fundamental problem of safe, physical human-robot interaction in dynamic, non-factory settings, Otsubo’s early research laid crucial groundwork for the collaborative robots (cobots) that are now prevalent in modern industry and service applications.
