In this paper, we developed a teaching material, a shooting robot system, for students studying application development in robotics, and evaluated its effectivity. Since robots, in general, make some action on the outside world in robot applications, students need to learn to model the relationship between sensing and actuation. In this paper, we take a shooting robot as an example, and designed a teaching materials for studying development of robot systems with awareness of cooperation between external sensors and robots. We conducted a robot contest to evaluate the proposed material. Students were split into groups and developed robot systems implemented using RT-components. Through this activity, they practically learned elemental technology for developing robot applications. We analyzed the result of the contest and the questionnaire to confirm the effectiveness of the proposed material in understanding of elemental technology and improvement of motivation for learning.
