Abstract: A robot cleaner includes a cleaner main body, a driver to move the cleaner main body, a sensor to sense an obstacle, and a sensor driver to rotate the sensor so that the sensor reciprocates in left and right directions within a predetermined angle range about a reference direction. In addition, a processor controls the driver to adjust a traveling direction of the cleaner main body based on the sensing result of the sensor, and to change the reference direction with a rotation direction if the cleaner main body is rotated.
