In this paper, the authors proposed the weeding robot system whose position is given from two single-point GPS receivers. One receiver is included in the robot and another is in the base station, and the position of the robot is given as the relational coordinate according to the base station. Then, the precision of the measurement is increased because the affection of the noise is cancelled. The efficacy of the developed system is confirmed by the measurement experiment at outdoors.
