Abstract

We developed an automated rice transplanter by modifying a commercial 6-row transplanter. Steering, transmission, and the transplanting implement were controlled through a controller area network (CAN). A network real-time kinematic (RTK) geographical positioning system (GPS) receiver was used for locating position, and an inertial measurement unit was used for measuring the vehicle posture. We developed path planning, straight-line, and turning control programs. The transplanter made 9 back and forth traverses planting long mat-type hydroponic seedlings. The deviation from the desired straight path had a root mean square of 0.052m during operation.
