    This paper presents the design and synthesis of a tilt-rotor mechanism for a hybrid UAV that can perform vertical takeoff and landing (VTOL) and fixed-wing flight. The tilt-rotor mechanism allows the orientation of the propulsion system to change from vertical to horizontal or vice versa, enabling the UAV to fly like a helicopter or an airplane. The paper describes the design, mathematical modeling, structural analysis, and fabrication of the mechanism, as well as the design and testing of a test bench and a control system. The paper also evaluates the performance of the mechanism and the system on a bi-copter UAV model and discusses the challenges, limitations, and future enhancements of the project. The paper concludes that the tilt-rotor mechanism is a promising solution for hybrid UAVs that can combine the advantages of both rotorcraft and fixed-wing UAVs.
