Dynamic Simulation of Tilted Rotor Quadcopter

International Journal of Innovative Technology and Exploring Engineering, 2019
Application of quadcopter unmanned aerial vehicle (UAV) has already become common today. As the name suggests, quadcopter has four rotors and these rotors can be classified into two types: fixed and tilted rotors. The maneuvering of quadcopter using the fixed rotor is achieved through the thrust differential.
