About

Takahiro Katayama is a robotics researcher whose work centers on assistive and rehabilitation robotics, with a particular focus on developing intelligent support systems for elderly care and nursing skill training. His research addresses one of modern society's most pressing challenges: the growing shortage of caregivers in aging populations, and the need for safe, effective robotic solutions to bridge that gap. Katayama's most influential contribution is his development of robotic walkers capable of supporting the full continuum of daily mobility — standing, walking, and sitting — rather than isolating individual functions, as many prior devices did. His 2015 robot patient for nursing transfer training (23 citations) demonstrated his innovative approach to simulation-based medical education, while his series of standing and sitting assistance systems refined user state estimation using minimal, cost-effective sensors to make care robots practically deployable in domestic settings. A distinguishing aspect of Katayama's research is his emphasis on human-robot trust and accountability. His 2019 work on accountable system design for embodied AI (15 citations) addresses transparency in learning-based autonomous robots — a critical concern as AI-driven care systems become more prevalent. With over 120 cumulative citations across his key works, Katayama's research makes meaningful contributions at the intersection of robotics, gerontechnology, and human-centered AI design.
