Cerberus is one of the four new teams in the RoboCup Tournament, Legged Robot Category. The team is a joint effort of Boğaziçi University (Turkey) and Technical University of Sofia, Branch Plovdiv (Bulgaria). We have divided the robot software design into six major tasks, and worked on those tasks in parallel. The tasks were locomotion, localization, vision, behavior control, learning and communication. With limited time in our hands, our aims were a clear object oriented design, readable behavior architecture, and maximum code reuse.
