Agro-bot

Agriculture faces several challenges such as labor shortage, inefficient use of water, lack of continuous soil monitoring, and excessive application of pesticides and fertilizers, which negatively affect productivity and sustainability. Manual farming operations including seed sowing, irrigation, and spraying are time-consuming, labor-intensive, and often result in uneven application and wastage of valuable resources. To address these limitations, this paper presents the design and development of a Smart Multi-Functional Agrobot that integrates robotics, sensor technology, and IoT concepts to enhance agricultural efficiency and reduce human effort. The proposed system is capable of performing essential farming tasks such as seed sowing, soil moisturebased irrigation, soil pH monitoring, and controlled pesticide spraying with improved accuracy. An Arduino Uno is used for controlling motors, pumps, and actuators, while an ESP32 module processes sensor data and enables wireless monitoring and future cloud connectivity. Sensor-based automation allows timely decision-making, optimized resource utilization, and reduced dependency on manual labor. The compact, modular, and cost-effective design makes the system suitable for small and mediumscale farmers. Experimental results demonstrate improved operational safety, efficient resource management, and environmentally sustainable farming practices, highlighting the strong potential of IoT-based automation in modern precision agriculture.
