First Claim
Patent Images
1. A robot cleaner comprising:
- a main body;
a driving unit moving the main body in a traveling direction at a traveling velocity;
a sensor unit sensing obstacles around the main body; and
a controller reducing the traveling velocity of the main body and causing the main body to approach a front obstacle, if an area where a plurality of obstacles contacts each other is sensed through the sensor unit.

Abstract
A robot cleaner includes a main body traveling along a floor surface and removing foreign substances in a cleaning travel mode, a sensor unit sensing obstacles around the main body, brush units sweeping foreign substances on a floor surface through rotation, and a controller reducing the traveling velocity of the main body and causing the main body to approach a front obstacle, if an area where a plurality of obstacles contacts each other is sensed by the sensor unit.

14. A control method of a robot cleaner comprising:
-
traveling a main body of the robot cleaner along a floor surface based on a normal cleaning travel pattern in a cleaning travel mode; sensing whether or not an area where a plurality of obstacles contacts each other is present in front of the main body through a sensor unit; and causing the main body to approach a front obstacle by reducing a traveling velocity, if the area where a plurality of obstacles contacts each other is present, as a result of sensing. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A robot cleaner comprising:
-
a main body; a driving unit moving the main body in a traveling direction at a traveling velocity; a front sensor sensing an obstacle located in a front region in the traveling direction of the main body; side sensors sensing obstacles located in side regions in the traveling direction of the main body; and a controller reducing the traveling velocity of the main body and causing the main body to approach a front obstacle, if the front sensor and the side sensors simultaneously sense obstacles.
