About

Noriyuki Tejima is a pioneering figure in rehabilitation robotics, a field at the intersection of mechanical engineering, biomedical engineering, and assistive technology. His research focuses on developing safe, practical robotic systems to aid individuals with disabilities, particularly in upper limb motion and daily activities like eating. Tejima’s most cited work, the 2001 review “Rehabilitation robotics: a review” (117 citations), provides a foundational taxonomy of the field, categorizing systems into rehabilitation robots, assistive devices, and therapeutic tools. He is perhaps best known for designing an 8-degree-of-freedom robotic orthosis (58 citations) that assists human forearm motion, emphasizing mechanical safety through innovative power-assist control. A hallmark of Tejima’s career is his dedication to safety and risk reduction; he proposed reflex mechanisms and fail-safe force sensors (9 citations) to prevent injury during human-robot interaction. He also developed objective evaluation indices for rehabilitation robots used in eating tasks (8 citations), addressing the gap between research prototypes and real-world adoption. Beyond engineering, Tejima critically examined the psychological and sociological implications of affective robots in mental therapy (7 citations), demonstrating a holistic view of technology’s societal impact. His work has shaped the safe, user-centered design of rehabilitation robots, influencing both academic research and clinical practice.
