A mobile robot is configured to move a main body and rotate a cleaning cloth by means of a motor to clean a surface. A location change of the main body is analyzed to determine a traveling state of the robot. The absence of the cleaning cloth is detected and the operation of the robot is controlled based on the detected travelling state. A user is notified about the absence of the cleaning cloth.

Moving robot and control method thereof

A mobile robot includes a body, a propulsion module, an ultrasound sensor module that is configured to detect a boundary of a cleaning area using a sound wave, and a controller configured to control the propulsion module based on the determined boundary. The ultrasound sensor module may include an ultrasonic sensor unit and a boundary detector. The sensor unit may emit the sound wave, receive the reflected sound wave from a target, and output a sound wave signal. And, the boundary detector may analyze the sound wave signal to detect the boundary of the cleaning area.

Moving robot

A autonomous robot includes a main body, a driving unit to move the main body within an operation region, a battery to supply power to the driving unit, and a controller to control the driving unit in a manner that the main body travels along a wall of the operation region to move to a charging stand when a remaining power level of the battery drops below a reference power level, wherein the controller controls the driving unit in a manner that the main body escape from one region corresponding to a closed curve when a movement path of the main body forms the closed curve while the driving unit performs wall following.

Moving robot and method of controlling the same

Disclosed are a robot cleaner and a self testing method thereof. The robot cleaner performs a self test when being initially operated or when required by a user. This may prevent malfunctions or breakdowns of the robot cleaner. Furthermore, the robot cleaner senses a state of an operation sensing unit provided at a body, based on a sensing signal of the operation sensing unit. This may prevent accidents or errors which may occur as the robot cleaner operates.

Robotic cleaner and self testing method of the same

A robot cleaner having a main body, a driving unit for moving the main body, a sensing unit for sensing information related to an obstacle, and a controller for controlling the driving unit to prevent collision of the main body with the obstacle. The controller controls the driving unit to reverse the main body with respect to the obstacle so as to prevent the main body from contacting the obstacle based on a distance between the main body and the obstacle.

Moving robot and controlling method thereof

Disclosed are a robot cleaner and a self testing method thereof. The robot cleaner performs a self test when being initially operated or when required by a user. This may prevent malfunctions or breakdowns of the robot cleaner. Furthermore, the robot cleaner senses states of components and sensors mounted therein, and performs a self test based on characteristics, output values, etc. of the components and the sensors. This may prevent accidents or errors which may occur as the robot cleaner operates.
