Heavy-lift Multirole Agricultural Drone with Zero Carbon Emissions*

This study presents the design and analysis of a hexacopter specifically engineered for agricultural applications, such as seed planting. The hexacopter is designed to lift a payload of 60 lbs to a hover height of 10 feet for a duration of 17 minutes. Detailed engineering calculations were performed to determine the necessary thrust, power, and battery capacity. The hexacopter features six T-Motor U8 Pro II motors, each delivering up to 750 W of power, paired with 15x5.5 Carbon Fiber Propellers to achieve optimal lift and efficiency. The propeller blade spacing and number of blades were designed to minimize vortex interaction, thereby enhancing aerodynamic performance and stability. The power system is supported by Tattu plus 6S 12000mAh 22.2V 15C LiPo Battery, ensuring sufficient energy supply for prolonged operations. Stress analysis confirms the robustness of the selected components under operational loads. This design demonstrates a feasible, cost-effective solution for agricultural tasks, specifically seed planting, by providing precise and efficient distribution over large areas. The proposed hexacopter design showcases significant potential for enhancing productivity and efficiency in agricultural operations.
