Abstract: A robot cleaner is provided. The robot cleaner includes a three-dimensional image sensor, an optical sensor, a gyro sensor, and at least one processor configured to control a driving state of the robot cleaner based on image data acquired by the three-dimensional image sensor, optical data acquired by the optical sensor, and angular velocity data acquired by the gyro sensor, wherein the three-dimensional image sensor and the optical sensor are respectively arranged to be tilted by a predetermined tilting angle, and a tilting angle of the three-dimensional image sensor is smaller than a tilting angle of the optical sensor.
