Abstract: This paper presents a novel uncrewed aerial vehicle (UAV) design named CASC. CASC uses a swashplateless mechanism and dynamic motor control to generate a moment for pitch and roll control without requiring additional actuators such as servo, reducing the number of components needed for control and enhancing reliability. Its reduced weight and number of actuators improve payload capacity and maneuverability. Meanwhile, CASC’s coaxial propulsion system and the aerodynamic design improve power efficiency. Through the hovering test in the multi-rotor state, we preliminarily verified the design of the UAV.
