Development of Robot Guidance System Using Hand-holding with Human and Measurement of Psychological Security

Abstract

Holding hands can give people a sense of security. In this study, we developed a five-fingered robotic hand that can hold hands with a person and a guidance system that uses the developed hand to hold hands with them. In this system, a robot remembers the location where people have taught it and guides people to that point. We conducted an experiment to evaluate the sense of security in guidance with hand-holding compared with guidance without hand-holding. Participants watched the videos on these two conditions and answered a questionnaire. The results confirmed that holding hands can lead to a sense of security.
