First Claim
Patent Images
1. A robot cleaner comprising:
- a traveling unit to move a main body;
an obstacle sensing unit to sense an obstacle;
a light reception unit 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 traveling unit to have the main body trace the light spot,wherein, if the obstacle is sensed, the controller further controls the traveling unit 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.

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.
