Abstract—The overturning of a drone causes personal losses and disturbances in residential communities. In general, unmanned aerial vehicles fly beyond the range that humans can reach in the sky. Recovering a drone from a fall is not easy. The conversion of a fuselage into a reasonable angle and using a propeller to operate lift are beneficial. The use of a flipping mechanism can eliminate such problems with overweight control. A rotatable arm mechanism was used to change the fuselage angle for obtaining an improved take-off posture through multiple attempts. The design process included concept drawing, functional element survey, functional simulation using a simplified model, and an environment scenario practice in determining appropriate design parameters. The chassis rotates beyond the vertical line when the arm is sufficiently long. A prototype model was constructed using an Arduino platform to integrate mechanical and electronic parts. Protection frames were added in the second prototype to improve stiffness.
