The increasing demand for efficient and sustainable agricultural practices has necessitated the development of advanced mechanized solutions for orchard and field crop management. This study focuses on the design, structural analysis and development of Remote Operated Vehicle (ROV) and Remote Operated Sprayer (ROS) unit and evaluation of a Remote Operated Vehicle (ROV) for addressing the challenges of precision spraying in orchard crop applications. The ROOS features, an innovative wheel arrangement and suspension system, optimized for manoeuvrability and adaptability in diverse field conditions. The power required to operate the ROOS was 1.48 kW. Structural analysis performed using ANSYS software verified the frame’s reliability, with principal stress, von Mises stress, and deformation values well within safe limits. Performance evaluations revealed a minimum path deviation of 29 mm at a 25 kg payload and 3.5 km/h speed and a maximum deviation of 90 mm at a 150 kg payload and 5 km/h. Battery discharge and wheel slip were minimal under lower payloads and speeds, with values of 0.87% and 4.15%, respectively. The study highlights the ROOS potential as an efficient and adaptable mechanized sprayer for orchard crops. The outcomes underline the ROOS capability to contribute to sustainable agricultural practices by improving spraying efficiency and reducing resource wastage.
