Our agent team AT Humboldt 2000 is partly an extension of our former team AT Humboldt 99[2,3]. Again we used a BDI architecture. Especially the world model and some skills where revised. A new timing concept and a completely different architecture for the deliberation component were developed. The actual development was subject of an undergraduate course. Because of problems with the integration of components developed by different work groups, we were forced to start in RoboCup 2000 with a mixed team, consisting mainly of an extended version of the players used in EuRoboCup 2000. Only the goalie used all our new concepts.
