ABSTRACT

This paper presents on-going work in developing service robots that provide assisted-care to the elderly in multi-party settings. In typical Japanese day-care facilities, multiple caregivers and visitors are co-present in the same room and any caregiver may provide assistance to any visitor. In order to effectively work in such settings, a robot should behave in a way that a person who has a request can easily initiate communication with the robot. Based on findings from observations at several day-care facilities, we have developed a robot system that displays availability to multiple persons and then displays recipiency to an individual person who wants to initiate interaction. Our robot system and its experimental evaluation are detailed in this paper.
