This project involved the end-to-end design, simulation, and validation of a quadcopter drone frame specifically optimized for aerial surveillance missio. With increasing demand for cost-effective, lightweight, and customizable UAVs, this project focuses on leveraging additive manufacturing technologies—particularly Fused Deposition Modelling (FDM)—to build a reliable and efficient drone frame that is both accessible and t Objectives:? Develop a drone capable of sustained 15+ minutes of continuous flight for surveillance operatio.? Eure structural integrity, optimized material usage, and seamless integration of key components such as moto, ESCs, flight controlle, and batteries.? Minimize frame weight while maintaining high mechanical strength to enhance overall flight efficiency and endurance.? Create a modular and upgradable platform, allowing future enhancements without complete redesign.? Utilize open-source electronic and mechanical components to eure replicability and affordability for educational, research, and small-scale applicatio.
