Abstract
RoboCup is an international joint project to promote Al, robotics, and related field. It is an attempt to foster Al and Intelligent robotics research by providing standard problems where a wide variety of technologies can be integrated and examined. For example, in RoboCup middle size league, the robots should recognized object colors (ball is orage, and goals are blue and yellow, etc.). And, in 2006, RoboCup middle size league decide to the color is affected by weather during the game. In this paper, we present the color recognition algorithm for RoboCup. This algorithm is used for color constancy algorithm of using modular network SOM. And, we present color recognition experiment in RoboCup environment.
