Abstract
The purpose of this study is to develop a wheel-type weeding robot in a paddy field. The weeding robot has a capacitive touch sensor to detect the rice plants, microcomputer and battery. The function of the sensor that is mounted on the weeding robot can detect rice plants and cannot be affected by water. In this paper, we design and develop two kinds of autonomous weeding robots. Kemp's linkages is used to keep the distance between the sensor and the robot main body. The effectiveness of the developed robots is verified by the preliminary experiments.
