Abstract
The objective of this study was to develop an automated rice transplanting system in paddy fields. It is necessary to determine the precise position a nd direction to control the vehicle automatically in paddy fields. In this paper, the position of the rice transplanter was determined by real-time ki nematic GPS (RTKGPS). The inclination of the rice transplanter influenced t he RTKGPS position data, including time delay because the GPS antenna was s et at a 2 m height from the ground. The correction can be performed by meas uring the roll, the pitch and the yaw angles of the rice transplanter. The yaw angle was measured using a fiber optic gyro (FOG) sensor and the roll a nd pitch angles were measured using an inclination-measuring apparatus cons isting of 3 FOG sensors and 3 accelerometers. When the rice transplanter wa s driven automatically along the desired straight path, the deviation from the desired straight path was less than 10 cm.
