Healthcare Robots, used in Japanese hospitals and healthcare facilities, are often functioning with low-fidelity capabilities. Intermediaries are needed in these situations. This article describes the model for the intermediary role of nurses in transactive relationships with healthcare robots. The intermediary role model is based on five assumptions that support nurses' functions: understanding the distinctive performance and value of robots, engaging in rehabilitation and recreation care activities with healthcare robots, encouraging providers of healthcare to utilize healthcare robots, and identifying issues about ethics, morality, security, and safety. Nurses as intermediaries practice nursing continuously with healthcare robots in the healthcare environment dense with technologies.
