Agricultural automation is becoming essential for improving productivity, farmer safety, and sustainable farming practices. Traditional activities such as manual pesticide spraying and grass cutting are labor-intensive and expose farmers to harm ful chemicals and physical strain. To address these challenges, this paper presents the design of a solar-powered Pesticide Sprayer Spider Robot integrated with a grass cutting mechanism for smart agricultural applications. The proposed system is built around a microcontroller-based architecture integrated with sensors such as ultrasonic sensors for obstacle detection, infrared sensors for spraying logic, and GPS for location tracking. The spider-like leg structure enables stable movement across uneven farm terrain where conventional wheeled robots may struggle. A compact pump and nozzle system performs targeted pesticide spraying, while a lightweight DC motor with blades enables efficient grass cutting. The robot can be controlled through an Android-based in terface that allows users to monitor sensor data and operate the system remotely. Experimental tests demonstrate effective obstacle detection, responsive spraying, and reliable grass cutting performance. The proposed system offers a low-cost, eco-friendly solution that reduces human effort and chemical exposure while supporting the development of precision agriculture.
