The RoboCup Symposium is a primary venue for presentation and discussion of scientific contributions to a variety of research areas related to all RoboCup leagues. Its scope includes, but is not restricted to, research and educational activities in robotics and artificial intelligence. Due to its interdisciplinary nature, the Symposium offers a unique venue for exploring both theory and practice in wide spectrum of research fields. The experimental, interactive, and benchmark character of the RoboCup initiative presents an opportunity to disseminate novel ideas and promising technologies, rapidly adopted and field-tested by a large, and still growing, community.
