Mini AgroBot for Smart Farming: An Intelligent Multipurpose Robot for Next - Gen Smart Farming

I. Abstract The increased demand for sustainable, precise, and efficient agriculture practices has led to the advancement of robotic farming, which is capable of automating diverse field operations. This literature review encompasses research papers from over the past decade on the integration of robots or smart farming. This review paper focuses on agricultural and field inspection tasks, emphasizing innovations in compact design, precision pest control, and software integration frameworks. Currently, most research focuses on only one application or purpose, such as only harvesting or sowing. It faces issues like high costs, complicated systems for local farmers with zero knowledge of the system, and adaptability across various farming environments. A critical analysis of recent studies highlights the advantages of multi-purpose designs, including improved resource utilization, operational flexibility, and environmental benefits, while also identifying limitations such as technical complexity and initial deployment barriers. The paper proposes an innovative solution focused on the integration of advanced sensing, precision pest control, and accurate ploughing and sowing. It also addresses the gaps, methodology, problems faced, the solutions adopted, and the design of the robot. Finally, it discusses future research directions, including AI-driven autonomy, scalable fleet operations, and strategies for wider adoption in small- to medium-scale farming contexts, underscoring the transformative potential of agricultural robotics in fostering sustainable and resilient food systems.
