This technology integrates several systems, including a tracked autonomous vehicle, 5G mobile communication, automatic wireless charging, AI-powered disease image recognition and precision spraying system. The sprayer vehicle autonomously navigates within greenhouses, continuously performing AI image recognition on the leaves of crops (such as cucurbits) at different growth heights to detect diseases like powdery mildew and downy mildew. It then automatically sprays the appropriate agents onto the affected areas, while also recording crop growth and pesticide usage. This achieves a precise and real-time automated disease control process. Paired with its automatic return-to-base wireless charging function, the system enables continuous 24/7 smart operations, effectively reducing labor requirements, chemical usage, carbon emissions, and operational safety risks.
