The death of potted plants with water shortage is caused by various reasons. Based on the problem and the actual demand, a networked intelligent watering robot with multinodes is proposed and designed in the paper, which can realize to control the distributed watering of potted plants. The watering robot includes a flower watering robot body, a pot planting network wireless node and a wireless network module., which can walk automatically according to the predetermined path, and the potted plants are selected to watering, which improve the efficiency of the watering robots; the actual humidity of the potted plants are according to the wireless measurement and realtime transmission, which improve the realtime of the flowers watering. Automatic watering ensures the needs of each pot, and quantitative and ondemand watering can save water resources, realize the unmanned management, which play a role in environmental protection and energy saving. The multinodes wireless controls improve the efficiency of watering robots, and reduce the piping layout, resource conservation.
