Abstract: The present invention provides an unmanned aerial vehicle that can maintain stability by changing positions of rotating rotors when one of the rotating rotors malfunctions, and a method for controlling stability of the unmanned aerial vehicle. The unmanned aerial vehicle includes: a main body; a plurality of support bars that are arranged while forming an angle with each other along a circumferential direction of the main body and extended to an outer side from the main body; a plurality of rotating rotors that are respectively provided to the support bars and generate thrust; motors that are respectively connected to the rotating rotors to drive the rotating rotors; drivers that change positions of the respective rotating rotors along the circumferential direction of the main body by moving the support bars with respect to the main body; and a controller that maintains horizontal stability of the main body by controlling the drivers.
