This paper describes a method of management of a lecture on the robot contest for many students. A lecture on robot contest has many merits. For example, the student not only learns engineering knowledge, but also develops problem-solving. However, there is often a problem that a lot of faculty staffs are needed to handle many students. Therefore, we divide the students into the group. And we teach the group how to solve a question, after the member of the group discusses the question. In this paper, the schedule is shown first. Next, the point of the lecture and effectiveness that we expect are illustrated. Finally, the result is discussed through the robot contest.
