A mobile robot using a drone technology according to an embodiment of the present invention includes at least two sub-mobile robots connected through a hinge configured of a servo motor, and each of the at least two sub-mobile robots generates a rotor airflow according to a control signal. And a plurality of rotors for generating thrust by varying air speed and air pressure in accordance with the rotor airflow, a mobile module attached to a wall according to the operation of a DC motor, and a distance to an obstacle in front of the sub-mobile robot. Sensor comprising a front sensor for sensing the sensor and a bottom sensor positioned on the bottom of the mobile robot for sensing the distance between the wall and the sub-mobile robot and the thrust generated by the plurality of rotors in accordance with the information received from the sensor Controlling to bend through the hinge by controlling or controlling the operation of the servo motor. A module and a remote control device communicating with a telecommunications module.
