    Abstract: A robot cleaner and a method for controlling the same are disclosed, which perform efficient cleaning by controlling a suction force or traveling route of the robot cleaner. The robot cleaner detects load applied to wheels of the robot cleaner so as to increase reliability and accuracy in floor state decision, thereby recognizing a floor state. The robot cleaner recognizes a floor state by combining load applied to wheels of the robot cleaner, load applied to brushes, and acceleration information of the robot cleaner with one another in a complementary manner, thereby increasing accuracy in floor state decision. The robot cleaner includes a traveling portion configured to include a traveling wheel to move a main body, and a wheel motor to provide the traveling wheel with drive power, a cleaning portion configured to include a brush module formed at a lower part of the main body to scatter dust or foreign substances accumulated on a floor on which the main body travels, and a suction module to suction the scattered dust or foreign substances, and a controller configured to determine a state of the floor, and control a suction force of the suction module and a traveling route of the main body according to the determined floor state.

    Abstract: A cleaning robot having improved traveling performance and a method of controlling the same. The cleaning robot detects a stuck state such as a ‘jammed state’, ‘lifted state’, or ‘object-caught state’ by using a motion instruction or sensor information and quickly escapes from the stuck state caused in various traveling conditions by using a wheel structure capable of changing a total height of the cleaning robot. In addition, a degree of risk and type of the stuck state is predicted before the cleaning robot is in the stuck state so that the cleaning robot may deal with the stuck state in advance. The cleaning robot may escape from the stuck state via rapidly deceleration or quick stopping in accordance with the predicted degree of risk of the stuck state, and the cleaning robot may efficiently deal with the stuck state by using information to select an escaping method suitable for the type of the stuck state.

    Abstract: An autonomous cleaner includes a body having a first housing formed at a front and a second housing formed at a rear of the first housing; a brush unit installed at the first housing and configured to sweep and collect dust from a floor; a dust collecting unit installed at the second housing and configured to store the dust inlet into the brush unit; a driving unit to drive the body and coupled to the second housing to be positioned at a lateral side of the dust collecting unit; and a power unit installed at the second housing and coupled to be positioned at a rear of the dust collecting unit. The miniaturization of the autonomous cleaner may be provided while at the same time the capacity of a dust collecting container and the capacity of a battery are increased.
