Robot cleaner and control method for the same
First Claim
1. A robot cleaner comprising:
- auxiliary cleaning units mounted to the robot cleaner, the auxiliary cleaning units being extendable and retractable from the robot cleaner to remove foreign matter from a floor while the robot cleaner travels on the floor to clean a cleaning region;
a sensing unit to sense operation states of the auxiliary cleaning units, respectively; and
a control unit to determine whether the auxiliary cleaning units operate normally based on the operation states sensed by the sensing unit, and, when one of the auxiliary cleaning units is not operating normally while another one of the auxiliary cleaning units is operating normally, to control travel of the robot cleaner so that the another one of the auxiliary cleaning units cleans an area adjacent to an edge portion of the cleaning region.

Abstract
A robot cleaner and a control method for the same are disclosed. The robot cleaner and control method are capable of detecting malfunction of an auxiliary cleaning unit, and controlling travel of the robot cleaner in accordance with the detection result, to achieve efficient cleaning of an edge area even when there is an error in the auxiliary cleaning unit. The robot cleaner includes a plurality of auxiliary cleaning units mounted to a bottom portion of the robot cleaner such that the auxiliary cleaning units are extendable and retractable, a sensing unit to sense an extension, retraction, or rotation state of each of the auxiliary cleaning units, and a control unit to determine whether the auxiliary cleaning units operate normally, based on a sensing result of the sensing unit, and to control travel of the robot cleaner, based on a result of the determination.

14. A robot cleaner comprising:
-
first and second auxiliary cleaning units mounted to the robot cleaner, the first and second auxiliary cleaning units being extendable and retractable from the robot cleaner to remove foreign matter from a floor while the robot cleaner travels on the floor to clean a cleaning region; a sensing unit to, while the robot cleaner travels on the floor to clean the cleaning region, sense operation states of the first and second auxiliary cleaning units, respectively; and a control unit to, while the robot cleaner travels on the floor to clean the cleaning region, determine whether the first and second auxiliary cleaning units are operating normally based on the operation states sensed by the sensing unit, and in response to the control unit determining that the first auxiliary cleaning unit is operating normally while the second auxiliary cleaning unit is not operating normally and thereby the second auxiliary cleaning unit thereby does not properly clean a portion of the cleaning region, control travel of the robot cleaner so that first cleaning unit cleans the portion of the cleaning region.
