Abstract: The present disclosure includes a main body, a cleaning tool assembly connected to the main body to be movable in at least one axial direction, a handle part connected to the main body and configured to receive an applied force of a user, a detection part provided in the handle part and configured to detect a magnitude and a direction of the force applied to the handle part, and a control part configured to control the movement direction of the cleaning tool assembly based on the detected direction of the force and to control the movement distance of the cleaning tool assembly based on the detected magnitude of the force. In this way, the steering performance may be improved by reducing a horizontal load felt by a user when the user holds and moves the handle of the cleaner, fatigue felt when performing the cleaning operation may be removed by removing a vertical load applied by the handle, and convenience may be improved.

Abstract: A cleaning robot includes a navigator to move a main body, a remote controller to output a modulated infrared ray in accordance with a control command of a user and to form a light spot, a light receiver to receive the infrared ray from the remote controller, and a controller to control the navigator such that the main body tracks the light spot when the modulated infrared ray is received in accordance with the control command. Because the cleaning robot tracks a position indicated by the remote controller, a user may conveniently move the cleaning robot.

Abstract: Disclosed herein are a driving unit and a robot cleaner having the same. The robot cleaner has a configuration in which an elastic member is supported so that an angle formed between the elastic member and a rotation shaft of the driving unit is provided in a predetermined range to offset a decrease in an elastic force generated while the robot cleaner is driving on a surface having steps and a driving wheel protrudes downward from the robot cleaner. Accordingly, there is the effect where a traction force is maintained at a predetermined level for maintaining the driving performance of the robot cleaner even while the robot cleaner is driving and the driving wheel is lowered to decrease the elastic force of the elastic member.
