Robot cleaner and method for controlling the same
First Claim
Patent Images
1. A method of controlling a robot cleaner comprising:
- receiving a command to perform a cleaning process;
recognizing, in response to the received command, a cleaning start location of the robot cleaner relative to a charger;
determining, by a controller, whether the recognized cleaning start location of the robot cleaner is at the charger; and
performing a spot cleaning process along a predetermined traveling pattern if it is determined the recognized cleaning start location is away from the charger,wherein the recognizing of the cleaning start location of the robot cleaner includes;
determining whether a voltage is detected at a charging terminal of the robot cleaner, the charging terminal being used to charge a battery of the robot cleaner when the charging terminal contacts the charger, anddetermining that the robot cleaner is located away from the charger when no voltage is detected at the charging terminal.

Abstract
A robot cleaner to perform a cleaning process by changing a traveling pattern according to a cleaning start position and a method for controlling the same are disclosed. The robot cleaner recognizes a current position of the robot cleaner upon receiving the automatic cleaning command. If the automatic cleaning process starts from the charger, the robot cleaner performs the automatic cleaning process using a conventional cleaning method. Otherwise, if the automatic cleaning process starts from the outside of the charger, the robot cleaner changes a traveling pattern, performs the spot cleaning process and then selectively performs the automatic cleaning process.

7. A robot cleaner charged by a charger, comprising:
-
an input unit to receive a command to perform a cleaning process; a sensor to detect, in response to the received command, a cleaning start position of the cleaner relative to the charger; and a controller to determine whether the detected cleaning start position is at the charger, and to perform a spot cleaning process along a predetermined traveling pattern if it is determined the detected cleaning start position is away from the charger, wherein the cleaning start location of the robot cleaner is detected by determining whether a voltage is detected at a charging terminal of the robot cleaner, the charging terminal being used to charge a battery of the robot cleaner when the charging terminal contacts the charger, and the controller determines that the robot cleaner is located away from the charger when no voltage is detect at the charging terminal. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A method of controlling a robot cleaner comprising:
-
receiving, by a controller, a command to perform a cleaning process; recognizing, in response to the received command, a current position of the robot cleaner relative to a charger by detecting a voltage detected at a charging terminal of the robot cleaner, using a charging sensor; determining, by the controller, whether the robot cleaner is positioned away from the charger or at the charger based on the detected voltage; and performing an automatic cleaning process if it is determined the recognized position is at the charger by cleaning a predetermined region along a first predetermined traveling pattern, and performing a spot cleaning process if it is determined the recognized position is away from the charger by cleaning a preferential region along a second predetermined traveling pattern, wherein the charging terminal is used to charge a battery of the robot cleaner when the charging terminal contacts the charger, wherein the recognizing of the robot cleaner location includes; determining whether a voltage is detected at a charging terminal of the robot cleaner, the charging terminal beinq used to charge a battery of the robot cleaner when the charging terminal contacts the charger, and determining that the robot cleaner is located away from the charger when no voltage is detected at the charging terminal. - View Dependent Claims (16, 17, 18)
