RoboCupJunior is a project-oriented educational initiative that sponsors local, regional and international robotic events for young students. It is designed to introduce RoboCup to primary and secondary school children, as well as undergraduates who do not have the resources to get involved in the senior leagues yet. The focus of the Junior league lies on education. The tournament offers to the participants the chance to take part in international exchange programs and to share the experience of meeting peers from abroad. RoboCupJunior offers several challenges, each emphasizing both cooperative and competitive aspects. For young students, RoboCupJunior provides an exciting introduction to the field of robotics, a new way to develop technical abilities through hands-on experience with electronics, hardware and software, and a highly motivating opportunity to learn about teamwork while sharing technology with friends. In contrast to the one-child-one-computer scenario typically seen today, RoboCupJunior provides a unique opportunity for participants with a variety of interests and strengths to work together as a team to achieve a common goal.
