Abstract: A robot cleaner having a monitoring function and minimizing power consumption and/or securing communication efficiency and a method of controlling a robot cleaner are provided. The robot cleaner may include at least one sound obtaining device; at least one image obtaining device; and a controller configured to determine whether a sound obtained through the at least one sound obtaining device is abnormal, sense a direction in which an abnormal sound is generated, and obtain images in the direction in which the abnormal sound is generated. The robot cleaner may automatically recognize a surrounding situation, and when necessary, the robot cleaner may rotate and/or move in a corresponding direction and/or position to obtain images or transmit the obtained images to a remote terminal, thereby minimizing power consumption of the robot cleaner with limited power.
