About
Atsushi Koujina is a robotics researcher specializing in assistive technologies for elderly care, with a particular focus on developing intelligent robotic systems that support the full spectrum of daily mobility — standing, walking, and sitting. His most influential work centers on the design and engineering of robotic walkers capable of providing seamless, continuous assistance across these interconnected motions, addressing a critical gap in previous devices that typically targeted only a single function. A hallmark of Koujina's research is his emphasis on user-centered design. His work on center-of-gravity (CoG) estimation using minimal sensor arrays demonstrates a commitment to making assistive robots both affordable and practical for domestic use. Notably, he has pioneered approaches that encourage users to engage their own physical strength within safe tolerance ranges, actively countering muscle deterioration — a concern often overlooked in conventional assistive robotics. Koujina has also made meaningful contributions to AI accountability in physical human-support robots, advocating for transparent, explainable autonomous systems that users can trust. His 2019 paper on accountable system design reflects a forward-thinking awareness of ethical dimensions in care robotics. With citations accumulating across more than a decade of work — including his most-cited paper drawing 19 citations — Koujina's research continues to shape the development of practical, intelligent, and humane robotic caregiving solutions.
