A method for controlling a robot cleaner includes: a step of controlling at least one of a first rotation member and a second rotation member to rotate depending on a traveling mode to travel the robot cleaner in a specific proceeding direction; a step of identifying whether or not an obstacle is detected from a sensor; and a step of setting a reference surface depending on the obstacle and controlling the first rotation member and the second rotation member to perform a wall movement pattern along the reference surface, in the case in which the obstacle is continuously detected.
