Abstract
There are growing needs for assistive robots which support independent life of elderly and disabled people or help people who work at the assistance and the nursing care. We are studying on establishment of the methodologies of developing such robotic care devices. We use ICF (International Classification of Functioning, Disability, and Health) and SysML in the development processes. In this paper, we describe the concept of modeling and requirements analysis using ICF and SysML, and show some examples of the model of nursing services focusing on transfer support activities. We also show some problems to solve in order to realize the concept of our studies.
