The underwater operation robot is an effective solution for addressing the inefficiencies and labor-intensive practices of traditional agricultural water management methods. This study aims to enhance efficiency, productivity, and resource utilization in agricultural water management by designing and analyzing an underwater-operated robot. Using SolidWorks software, the robot undergoes comprehensive stress and strain simulations to evaluate structural integrity and propeller performance, while computational fluid dynamics (CFD) simulations assess hydrodynamic performance and flow characteristics. Results from structural analysis at a depth of 3 meters reveal stress values ranging from 3.531e-07 N/m² to 3.076e+05 N/m² on the robot’s body, with minimal displacement (1.000e-30 mm to 4.634e-03 mm) and no material yielding. At 3500 rpm, stress simulations demonstrate rear propeller stress ranging from 1.921e-01 N/m² to 1.139e+05 N/m², with displacement (1.000e-30 mm to 1.9993e-04 mm), ensuring structural safety. Similarly, left and right propellers exhibit stress values from 1.202e-01 N/m² to 1.269e+05 N/m², with displacement (1.000e-30 mm to 1.545e-04 mm), confirming structural integrity. CFD simulations depict velocity (ranging from 0.895 to 3.582 m/s) and pressure (ranging from 98,021.83 to 105,498.84 Pa) variations for different movements, such as forward motion, turning left, and turning right. These simulations offer valuable insights into the robot's performance in agricultural water management. The research presents an underwater-operated robot as a promising solution for agricultural water management, offering enhanced efficiency, automation, and resource optimization, potentially reducing labor costs
