The subject of "Championship" is executed at the first semester as the first-year experience. The championship of a robot, which is mentioned in this paper, is executed at the last four times of the fifteen times as an example of the active learning. A simple robot named "RaspberryPi Mouse" with a control computer named "RaspberryPi" was introduced to execute the championship. Concretely, students learned first the mechanism of the robot and then explored the optimal parameters through repeating the process of the thinking and experiment. It looks like that the students attended and learned the subject voluntary and enthusiastically.
