Cleaning robot and control method thereof
First Claim
1. A cleaning robot comprising:
- a battery;
a moving unit that is drivable to move the cleaning robot;
a cleaning unit that is drivable to perform a cleaning operation;
a power converter to convert and output power supplied from the battery into a first power to drive the moving unit and a second power to drive the cleaning unit; and
a controller configured to;
supply the first power to the moving unit so as to drive the moving unit to move the cleaning robot,supply the second power to the cleaning unit so as to perform the cleaning operation, andwhen determined by the controller that the cleaning robot will move through an already cleaned areas of the cleaning area, determine whether to interrupt the supplied second power while passing through the already cleaned area and then re-supply the second power based on at least one of a time of travel of the cleaning robot and a distance of travel of the cleaning robot necessary to pass through the already cleaned area,wherein the controller either interrupts or maintains the second power being supplied to the cleaning unit according to the determination to optimize power saving during operation.

Abstract
A cleaning robot and a control method thereof may improve power consumption efficiency by using low-voltage power for a moving or inspecting operation and performing the moving or inspecting operation while operation of the cleaning unit is stopped when the operation of the cleaning unit is not needed. The cleaning robot includes a battery, a moving unit, a cleaning unit, a power converter which converts and outputs power supplied from the battery into a first voltage driving the moving unit and a second voltage driving the cleaning unit, and a controller which supplies power having the first voltage to the moving unit so as to drive the moving unit and supplies power having the second voltage to the cleaning unit so as to perform a cleaning operation. The controller continues driving the moving unit but stops driving the cleaning unit when the cleaning robot moves on an already cleaned area.

7. A method of controlling a cleaning robot, comprising:
-
receiving power having a first voltage from a battery, driving a moving unit using the first voltage, and moving on a cleaning area; receiving power having a second voltage, which is higher than the first voltage, from the battery, driving a cleaning unit using the second voltage, and performing a cleaning operation on the cleaning area; when determined by the controller that the cleaning robot will move through an already cleaned areas of the cleaning area, determining whether to interrupt the second voltage while passing through the already cleaned area and then re-supply the second voltage, based on at least one of a time of travel of the cleaning robot and a distance of travel of the cleaning robot necessary to pass through the already cleaned area; and either maintaining or stopping the cleaning operation based on the determination to optimize power saving during operation. - View Dependent Claims (8, 9)

10. A robot comprising:
-
a moving unit that is drivable to move the robot; a cleaning unit that is drivable to perform a cleaning operation; and a controller to; supply a first power to the moving unit to thereby drive the moving unit to move the robot, supply a second power to the cleaning unit to thereby drive the cleaning unit to clean a surface while the robot is being moved by the moving unit, while the robot is cleaning the surface, when determined by the controller that the cleaning robot will move through an already cleaned areas of the cleaning area, determine whether to interrupt the supplied second power while passing through the already cleaned area and then re-supply the second power based on at least one of a time of travel and a distance of travel of the robot necessary to pass through the already cleaned area, wherein the controller either interrupts or maintains the supply of the second power to the cleaning unit while continuing to supply the first power to the moving unit so that the robot continues to be moved by the moving unit with the cleaning by the cleaning unit being either maintained or stopped to optimize power saving during operation.
