This work presents the development of an Omni-directional Unmanned Aerial System (OUAS) with a focus on system integration from a mechatronics perspective. A dynamic model is first derived to characterize the system’s behavior, accompanied by a representation of the vehicle to visualize force and torque distributions. The mechanical structure is designed using computer aided (CAD) tools and validated through finite element analysis (FEA) to ensure structural integrity under operational loads. The electrical subsystem is then detailed to support the integration of propulsion, control, and navigation components. A vehicle model is developed using Plane Maker based on blade element theory (BET) for preliminary simulation. To enable flight testing in a virtual environment, a simulation framework is established using the X-Plane physics-based simulator in conjunction with the Robot Operating System (ROS) for real-time communication and control. This integrated and multidisciplinary approach enables the design of a highly agile and responsive aerial platform suitable for advanced control implementation and diverse application scenarios.
