Abstract
A robot cleaner includes a main body, a traveling unit, a cleaning unit, a sensor unit, and a controller. The traveling unit allows the main body to travel. The cleaning unit suctions foreign substances around the main body during the traveling. The sensor unit is rotatable and senses an obstacle using light reflected or scattered by the obstacle. The controller controls the traveling unit so as to travel along a traveling path and controls the cleaning unit so as to perform cleaning. Here, the sensor unit includes a first mode and a second mode that are set to differ from each other in sensitivity with respect to the reflected or scattered light, and the controller changes the sensitivity of the sensor unit according to a traveling mode.
