With the extensive use of robots in recent years, an age of co-existence between humans and robots is expected to arrive in the future. Therefore, providing robot education in the early stages of elementary and junior high school is necessary to stimulate students' interest in robots. Furthermore, educational institutions are becoming more active in robot education as a part of their contribution to the local community. For elementary school students, a Beauto Racer (Vstone) has been adopted as a teaching material for robot education, and teaching materials have been developed for teaching line tracing. In this study, we will develop educational materials for junior high school students on maze exploration using a Beauto Rover (Vstone). The students of Matsue National College of Technology took the initiative in this activity. The purpose is to improve their teaching skills.
