With the continuous updating of aquaculture varieties, diseases in aquaculture are constantly changing, clinical treatment is becoming more and more difficult, and the use of medicine is increasing. Aiming at the characteristics of high labor cost, high labor intensity and low efficiency caused by artificial spraying in large area aquaculture, a pond intelligent spraying boat is designed. In addition to the traditional hull, propeller and steering engine, the pond intelligent spraying boat also has an intelligent system composed of communication positioning module, electromechanical control module and remote control module based on Android platform. The route is planned with the remote control module, and the electromechanical control module is controlled with the communication positioning module on the boat, so as to achieve the purpose of operating the intelligent spraying boat to advance, turn and spray. The results show that after the route is planned by the intelligent spraying boat, compared with artificial spraying, the labor intensity is reduced by more than 90% and the efficiency of spraying is increased by 6.5 times. Moreover, the spraying is even, which reduces waste and reduces the impact of the drugs on health of the operators. The research shows that the design of intelligent spraying boat can change the traditional spraying mode and promote the technological progress of aquaculture.
