Boom sprayer is usually used in Hokkaido for chemical application of upland crops. We developed the application rate control system of boom sprayer in proportion to working speed by using RTK-GPS and the flow rate sensor. And an automatic boom opening and closing system, which works at every start and end of spraying was also developed for autonomous spraying. Using this sprayer and the robot tractor equipped with RTK-GPS and CAN-BUS, we did the verification of autonomous spraying system in sugar beet field. The autonomous running of tractor, application control system and boom control system of sprayer was smoothly activated. Thus, this system can enable an autonomous spraying.
