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.

Robot cleaner and controlling method thereof

A robot cleaner has a camera to generate an image of a cleaning area, a controller to prepare a cleaning map based on the image and to drive a robot cleaner, and a communicator to transmit the image and cleaning map to an external device and to receive a control command from the external device. The image and map may be transmitted over a local or wide area network, and the external device may be a computer, television, smart phone, portable phone, or other type of wireless access device.

Robot cleaner and remote monitoring system using the same

Disclosed are a mobile robot and a controlling method of the same. The mobile robot is capable of reducing a position recognition error and performing a precise position recognition even in the occurrence of a change of external illumination, through geometric constraints, when recognizing its position with using a low quality camera (e.g., camera having a low resolution). Furthermore, feature points may be extracted from images detected with using a low quality camera, and the feature points may be robustly matched with each other even in the occurrence of a change of external illumination, through geometric constraints due to the feature lines. This may enhance the performance of the conventional method for recognizing a position based on a camera susceptible to a illumination change, and improve the efficiency of a system.

Control of mobile robot by detecting line intersections

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.
