India is a farmland, with agriculture accounting for three-fourths of its population. Farmers produce numerous plants in their fields based on available resources and climate. However, some technical abilities, in addition to technological Assistance is needed to attain high output and outstanding quality. In agriculture, every leaf matters. Often requiring labor-intensive spraying of pesticides. That’s where our innovation, the Semi-Automatic Pesticide Sprayer Bot, comes in. The proposed framework introduces an innovative sprayer arrangement aimed at reducing pesticide usage by precisely targeting individual areas. By adjusting the spraying distance based on the target, the device minimizes pesticide application. The potential savings depend on factors like spraying duration, target size, and distribution. This technology is suitable for modern agriculture, especially when integrated with autonomous sprayers that traverse fields independently. By capturing input images with a camera and employing machine learning algorithms, the system detects diseases on leaves, stems, or plants, as well as areas vulnerable to disease, and predicts appropriate remedies. This precise targeting is crucial for optimizing pesticide spraying. The robot’s movement is facilitated by the L293D motor driver, while the Raspberry Pi 3 serves as the processor or embedded system. Python code is utilized for machine learning, enabling the robot to learn from predefined images. The ability to control the system remotely, thereby avoiding direct exposure to pesticides while working in the fields, offers significant benefits to farmers.
