Robot cleaner and method for controlling the same
First Claim
1. A robot cleaner for removing foreign matter from a floor while traveling on the floor, comprising:
- a body;
a main brush unit mounted to a bottom of the body of the robot cleaner;
a plurality of auxiliary cleaning units mounted to the bottom of the body of the robot cleaner, each being protrudable outward from the body of the robot cleaner to a protruded position and retractable into the body of the robot cleaner to a retracted position; and
a control unit configured tocontrol the robot cleaner to travel in a wall tracing manner of travel along a periphery of a cleaning region, andextend at least one of the auxiliary cleaning units from the retracted position thereof to the protruded position thereof in response to determining that the robot cleaner has been set to travel in the wall tracing manner of travel.

Abstract
Disclosed are a robot cleaner and a method for controlling the same, capable of controlling a travelling or cleaning pattern of a robot cleaner in accordance with extension and retraction operations of an auxiliary cleaning tool to perform an efficient cleaning operation. The robot cleaner includes a plurality of auxiliary cleaning units mounted to a bottom of the robot cleaner such that the auxiliary cleaning units are extendable and retractable, and a control unit to extend the auxiliary cleaning units while travelling in a wall tracing manner along the periphery of the cleaning region and/or when an obstacle is sensed, and to retract the auxiliary cleaning units while the robot cleaner travels in an inner portion of the cleaning region when traveling of the periphery of the cleaning region is finished.

11. A method for controlling a robot cleaner comprising a main brush unit, and auxiliary cleaning units each being protrudable outward from a body of the robot cleaner to a protruded position and retractable into the body of the robot cleaner to a retracted position, the method comprising:
-
determining whether or not the robot cleaner has been set to travel in a wall tracing manner of travel along a periphery of a cleaning region; outwardly extending at least one of the auxiliary cleaning units from the retracted position thereof to the protruded position thereof, in response to determining that the robot cleaner has been set to travel in the wall tracing manner of travel; determining whether the robot cleaner is no longer travelling in the wall tracing manner of travel; and retracting the at least one auxiliary cleaning units to the retracted position thereof in response to determining that the robot cleaner is no longer travelling in the wall tracing manner of travel. - View Dependent Claims (12, 13, 14, 15, 16)
