Center pivot irrigation systems are widely used for large-scale agricultural irrigation, providing uniform water distribution. However, their circular coverage leaves field corners unwatered, reducing efficiency and requiring additional irrigation infrastructure. To address this, swing arm extensions are attached to the last tower of the center pivot, improving coverage. Despite their benefits, current swing arm systems require further optimization in control mechanisms to enhance accuracy, automation, and maneuverability while reducing operational costs. Existing swing arm control solutions primarily rely on buried cables, hydraulic actuators, or electromechanical systems. These approaches, while functional, present significant drawbacks, including high installation and maintenance costs, susceptibility to wear, and limited adaptability to real-time field conditions.
