Abstract
This paper describes the implementation of dynamic passes and receives for RoboCup Soccer Middle Size League. In RoboCup Soccer Middle Size League, the competition rules prohibited the robot from dribbling over the mid field line. Therefore it is necessary to pass the ball. Determine of the pass courses is proposed passer considered with ball reachable distance and arrival time. In addition, reachable range of the receiver is drawn on a simulator. Availability of pass is determined by cross decision between pass courses and maximum reachable range of the robot. The experiments are conducted in an environment of game format using the simulator, and discussed value from pass success rate. Result, by the proposal method, the pass success rate is about 60-80%. Proposal method shows the value.
