RoboCup 2009

We are really pleased to present the proceedings of the RoboCup International Symposium 2009. The 13th RoboCup Symposium was held in conjunction with the RoboCup 2009 competition in Graz, Austria from June 29 to July 5, 2009. The symposium highlights the many research contributions and achievements of the RoboCup community. Contributions from all leagues (RoboCupSoccer, RoboCupRescue, RoboCup@Home, and RoboCupJunior) are included in the symposium. The papers published in these proceedings are not limited to prac- cal issues, but also include fundamental research, system evaluation, and robotics education topics. There were 112 submissions from 25 countries. All papers were carefully - viewed by an international Program Committee of 96 members, who were - sisted by 25 additional reviewers. Each paper was reviewed by three Program Committee members and all reviews were carefully considered and discussed by the Symposium Co-chairs, who made the ?nal decisions. The review process was extremely selective and many good papers could not be accepted for the ?nal p- gram. Out of the 112 submissions, 22 papers were selected for oral presentations, whereas 17 papers were selected for poster presentations. Two of these papers were recognized for their outstanding quality. Speci?cally, Mohsen Malmir and Saeed Shiry received the best paper award for their paper titled "Object Rec- nition with Statistically Independent Features: A Model Inspired by the Primate Visual Cortex" and Shivaram Kalyanakrishnan and Peter Stone received the best student paper award for their paper titled "Learning Complementary Mutliagent Behaviors: A Case Study".
