This paper describes an autonomous weeding robot with Archimedean screws for paddy fields. Our weeding robot has four Archimedean screw wheels, and can move forward/backward and turning, in addition, just besides direction in muddy paddy field. By using these wheels, the robot runs along a paddy row by trampling some still small weeds, and supresses their growth. In this study, we propose image processing and control methods for the robot to recognize paddy row to move along and/or change one. Using the developed method, preliminary indoor/outdoor experiments have shown a good performance.
