About

Dr. Hiroshi Tajima is a pioneering researcher in the field of flexible robotics and structural dynamics, with a focused expertise in motion and vibration control of lightweight, elastic manipulators. His major contributions center on developing advanced modeling and control strategies for flexible multibody systems, particularly for applications in space robotics where high-speed, high-precision operation is critical. Dr. Tajima is best known for proposing the Extended Reduced-Order Physical Model (Extended Model), a novel framework that enables simultaneous motion and vibration control of elastic structures under arbitrary boundary conditions. This work addresses the fundamental challenge of structural flexibility—where lighter arms reduce natural frequencies and increase vibration—by providing a systematic method for controller design. While his most-cited papers have garnered 2 citations each, their impact is significant within the specialized domain of flexible robot arm control, laying groundwork for future innovations in space-based automation. Dr. Tajima’s research bridges theoretical modeling with practical control implementation, offering essential insights for engineers developing next-generation, high-performance robotic systems.
