  • Robot cleaner and controlling method of the same
    Patent number: 8705842
    Abstract: 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.

  • ROBOT CLEANER AND CONTROLLING METHOD OF THE SAME
    Publication number: 20110125324
    Abstract: 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.
