1. A robot cleaner comprising:
- a main body;
a wheel-driving motor and a traveling wheel to move the main body;
an obstacle sensor to sense an obstacle;
a light receptor to receive a position of a light spot of modulated light formed according to a control command of a user; and
a controller configured to control the wheel-driving motor and traveling wheel to have the main body trace the light spot,wherein, when the obstacle is sensed, the controller further is configured to control the wheel-driving motor and traveling wheel such that the main body traces an outline of the obstacle according to the position of the light spot and a position of the obstacle to travel to the light spot position along a minimum path,wherein the controller performs any one of a right tracing traveling in which a right side of the main body travels toward the obstacle and a left tracing traveling in which a left side of the main body travels toward the obstacle according to the minimum path to the light spot position, andwhen the obstacle is located on a traveling direction of the main body, the controller is configured to control the wheel-driving motor and traveling wheel so that the main body rotates toward the light spot and traces the obstacle outline.

Abstract
A robot cleaner includes a traveling unit to move a main body, an obstacle sensing unit to sense an obstacle, a light reception unit to receive modulated light according to a control command of a user, and a controller to control the traveling unit so that the main body traces a light spot formed by the light. If an obstacle is detected, the controller controls the traveling unit such that the main body traces an outline of the obstacle according to the light spot position and the obstacle position.

14. A method for controlling a robot cleaner having a main body and a controller, comprising:
-
receiving modulated light including a control command of a user by the controller; tracing a light spot formed by the light; and detecting an obstacle, wherein when the obstacle is detected, performing any one of right tracing traveling and left tracing traveling according to a position of the light spot and a position of the obstacle and traveling to the light spot position along a minimum path via right tracing traveling or left tracing traveling according to the minimum path, the performing of any one of the right tracing traveling and the left tracing traveling includes when the obstacle is located on a traveling direction of the main body and the light spot is located at a right side of the obstacle, performing the left tracing traveling, and when the obstacle is located at a traveling direction of the main body and the light spot is located at a left side of the obstacle, performing the right tracing traveling. - View Dependent Claims (15, 16)
