Abstract: Efficient and safe pesticide application remains a significant challenge in small- and medium-scale agriculture in India, where manual spraying exposes farmers to harmful chemicals and limits operational productivity. This study presents the design, development, and testing of a solar-powered, remote-controlled automatic pesticide spraying robot. The system integrates mechanical, electrical, and control subsystems, including DC motors for wheel movement, a DC pump for spraying, a multi-nozzle assembly, rechargeable batteries, and a Bluetooth-based control unit. The robot provides uniform pesticide distribution, adjustable nozzle height, and autonomous navigation over uneven terrain. Experimental results demonstrate that the robot can cover wide areas efficiently, with a flow rate of 3.16 liters per minute through four nozzles and a remote operation range of up to 50 meters, minimizing operator exposure to chemicals. The solar-assisted power supply ensures sustainable operation in rural areas with limited electricity access. The proposed system reduces labor requirements, enhances spraying uniformity, and provides a cost-effective, safe, and practical solution for agricultural pesticide application and disinfection in public spaces.
