20110125324 | ROBOT CLEANER AND CONTROLLING METHOD OF THE SAME - A robot cleaner and a method of controlling a robot cleaner are provided. The robot cleaner is capable of automatically compensating for and adjusting a moving angle and a position using an appropriate sensor and control algorithm while performing a cleaning operation in a relatively large space. This may reduce a position error, allow a cleaning region to be effectively identified as a region to be cleaned or a region having already been cleaned, thus improving cleaning performance and efficiency. | 05-26-2011 |
20110239382 | ROBOT CLEANER - A robot cleaner includes wheels mounted at a lower side of a main body of the robot cleaner to allow for traveling of the main body, and wire winding prevention members mounted at the lower side of the main body, each wire winding prevention member having one end extending to be contactable with a rim of the corresponding wheel. The wire winding prevention member is preferably a torsion spring. | 10-06-2011 |
20120106829 | ROBOT CLEANER AND CONTROLLING METHOD OF THE SAME - A robot cleaner and a method for controlling the same are provided. A region to be cleaned may be divided into a plurality of sectors based on detection data collected by a detecting device, and a partial map for each sector may be generated. A full map of the cleaning region may then be generated based on a position of a partial map with respect to each sector, and a topological relationship between the partial maps. Based on the full map, the robot cleaner may recognize its position, allowing the entire region to be completely cleaned, and allowing the robot cleaner to rapidly move to sectors that have not yet been cleaned. | 05-03-2012 |
20120109376 | CLEANER AND CONTROLLING METHOD OF THE SAME - Disclosed are a robot cleaner and a method for controlling the same. The robot cleaner may prevent repeated executions of a cleaning operation by recognizing its position through an absolute position recognition unit, in a case that the cleaning operation is performed again after being forcibly stopped due to arbitrary causes. And, the robot cleaner may solve a position recognition error by a relative position recognition unit with using an image detection unit, and may effectively perform a cleaning operation based on a similarity between an image detected by the image detection unit and an image with respect to a cleaning region. This may improve the system efficiency and stability, and enhance a user's convenience. | 05-03-2012 |
20120232697 | ROBOT CLEANER AND CONTROLLING METHOD THEREOF - Disclosed are a robot cleaner capable of performing a cleaning operation by selecting a cleaning algorithm suitable for the peripheral circumstances based on an analysis result of captured image information, and a controlling method thereof. The robot cleaner comprises an image sensor unit configured to capture image information when an operation instructing command is received, and a controller configured to analyze the image information captured by the image sensor unit, and configured to control a cleaning operation based on a first cleaning algorithm selected from a plurality of pre-stored cleaning algorithms based on a result of the analysis. | 09-13-2012 |
20130073088 | MOBILE ROBOT AND CONTROLLING METHOD OF THE SAME - In a mobile robot and a controlling method of the same, the mobile robot is able to recognize a precise position thereof by detecting a plurality of images through an image detection unit, extracting one or more feature points from the plurality of images, and comparing and matching information related to the feature points. The mobile robot is also able to easily detect a position of a charging station based on image information, and quickly move to the charging station upon the lack of residual battery capacity. The mobile robot is also able to detect a position of the charging station based on the image information and receive a guideline signal within a signal reception range, so as to easily dock with the charging station. | 03-21-2013 |
20130116825 | ROBOT CLEANER AND CONTROLLING METHOD OF THE SAME - Disclosed are a robot cleaner and a method for controlling the same. A plurality of images are detected through an image detecting unit such as an upper camera, and two or more feature points are extracted from the plurality of images. Then, a feature point set consisting of the feature points is created, and the feature points included in the feature point set are matched with each other. This may allow the robot cleaner to precisely recognize a position thereof. Furthermore, this may allow the robot cleaner to perform a cleaning operation or a running operation by interworking a precisely recognized position with a map. | 05-09-2013 |
20130204483 | ROBOT CLEANER - A robot cleaner is provided. The robot cleaner may include a casing including a moving device, an image input disposed in the casing, the image input including a plurality of light emitting parts that emits light toward an obstacle and an image sensor that acquires a 3D image of the obstacle onto which the light is emitted by the plurality of light emitting parts, and a main controller that extracts 3D data with respect to the obstacle from the 3D image of the obstacle acquired by the image input to control the moving device. | 08-08-2013 |
20130338831 | ROBOT CLEANER AND CONTROLLING METHOD OF THE SAME - A robot cleaner is provided. The robot cleaner may precisely detect a peripheral obstacle using a particular optical pattern. An asymmetric cross-shaped optical pattern may be irradiated, and a pattern image with respect to the optical pattern-irradiated region may be analyzed to determine whether or not an obstacle is in the moving path, and a width or a height of the obstacle. Further, the robot cleaner may perform operations such as a forward motion, a backward motion, a stopping motion and a detour motion, based the obstacle detection result. | 12-19-2013 |
