This study aims to design and fabricate an agricultural spraying drone equipped with a two-axis gimbal nozzle and a variable landing-guard system. Conventional agricultural spraying drones[1] generally use fixed nozzles, which cause the spray direction to change according to the attitude variation of the drone body during flight. This may lead to pesticide drift, reduced spraying accuracy, and environmental contamination. To address this problem, a two-axis gimbal nozzle was implemented to maintain the spray direction independently of the drone body motion. In addition, a variable landing-guard system utilizing a four-bar linkage mechanism was developed to integrate the functions of landing gear and propeller guards into a single structure. The proposed system was designed using three-dimensional modeling, and its aerodynamic and dynamic characteristics were evaluated through ANSYS and ADAMS analyses. A prototype was fabricated using 3D-printed parts and assembled with an S500 drone frame. The basic operation of the gimbal nozzle, water pump, and variable landing-guard mechanism was verified through prototype tests.
