Robot communication based on relational trust model

In this study, we aim to develop a system for improving daily lives of elderly people to ensure health. In order to realize an enriched life style among elderly people, daily health care is important. Therefore, we have proposed a system where robot partners will assist in exercising activity among elderly people. This paper proposes a method of relational trust modeling based on reinforcement learning. We apply a concept of relational trust defined as the expectation that a person is disposed to act in a trustworthy manner toward "me," no matter what the person does to others. In the experiment, we discuss the effectiveness of relational trust for robot communication.
