Abstract
The purpose of this study is to develop a sensor system for a weeding robot in order to detect the end of rows of rice plants in a paddy field. The sensor system has two capacitive touch sensors to detect the rice plants. The function of the sensor system that is mounted on the weeding robot is to detect rice plants, it cannot be affected by another sensor or the robot main body. In this paper, we carried out two types experiments using imitations of the rice plant in a sandbox. The effectiveness of the developed sensor system is verified by the experiments.
