EIGEN participates in RoboCup at World Meeting for the rst time. Our team provides three robots of the same type and one goalkeeper robot. Our aim is to realize a cooperative team play among robots as well as high performance of robot relating to image processing, decision making of behaviors, and motion control. As a rst step, we realized a motion control for a eld-player robot by the Fuzzy control method and cooperative behaviors by a wireless LAN. 1 Hardware Architecture
