A charging device of a robot cleaner is provided. The charging device of a robot cleaner according to the embodiment includes at least one cover forming an appearance of the charging device, a base which is coupled with the cover and includes a terminal unit for charging the robot cleaner, an induction signal generating unit disposed at a side of the cover or the base to transmit a return induction signal to the robot cleaner, and an induction signal guide member disposed at a side of the induction signal generating unit to enhance a docking performance of the robot cleaner by improving linearity of the induction signal. The charging device according to the embodiment can guide the path for the return of the robot cleaner and recharge the robot cleaner stably.

Charging device of robot cleaner

Provided is a robot cleaner. In an embodiment, the robot cleaner for avoiding obstacles and sucking foreign materials using a plurality of sensors and a suction motor is characterized in that a drive suppression unit for detecting obstacles having a corresponding height is integrated with a base for forming a lower portion of a main body in order to not climb obstacles of a constant height during a driving period of the robot cleaner. The present disclosure according to the embodiment improves drive stability of the robot cleaner by sensing a threshold in erroneous state of the sensor for sensing the threshold.

Robot cleaner

Provided is a robot cleaner, and more particularly to a robot cleaner which detest whether a foreign material storage unit is separated. The robot cleaner includes a main body including a suction motor, a foreign material storage unit separably disposed within the main body, the foreign material storage unit storing foreign materials contained in sucked air, a foreign material cover for selectively shielding one side of the foreign material storage unit, and a detection unit for detecting whether the foreign material cover is opened.

According to an embodiment of the present disclosure, an installation structure for an agitator installed in a dust suction unit of a robot cleaner to scatter foreign substances distributed in a working area comprises: a holder which is connected to a driving motor for providing a torque to the agitator and has a part exposed to the inside of the dust suction unit; and a fixing shaft for forming a rotation shaft of the agitator and having a shape of a polygonal pillar or a shape of a pillar including at least one projection, wherein a shaft insertion part is formed in the holder, has a dented shape corresponding to the shape of the fixing shaft, and can be engaged and rotated with the fixing shaft while the fixing shaft is inserted into and installed at the holder. According to an embodiment of the present disclosure, the easy separation and installation of the agitator and the enablement of simultaneous rotation of the agitator and a side brush can improve user satisfaction.

Provided is a robot cleaner, and more particularly to a robot cleaner for shielding particularly an air inlet of a foreign material storage unit. The robot cleaner includes a main body including a drive unit for providing a suction force, a main cover for shielding a side of the main body, a foreign material storage unit separably disposed on the main cover, the foreign material storage unit having an air inlet for introducing air containing foreign materials, a foreign material cover disposed on the main cover, the foreign material cover selectively shielding a side of the foreign material storage unit, and a shield member disposed on the foreign material storage unit, the shield member selectively shielding the air inlet.

A robot cleaner including: a main body; and an RF antenna installed at the main body with such a length appropriate for communication with a remote controller. Because the RF antenna is installed within the main body, the degradation of traveling performance and cleaning efficiency caused as the antenna contacts with an external obstacle can be prevented.

Robot cleaner having RF antenna

Disclosed is a pressing sensing technology of a self-running robot, comprising a pressing sensing unit for sensing pressing on the top of the self-running robot and a microprocessor for controlling driving of the self-running robot in accordance with the sensing signal from the pressing sensing unit to enable the self-running robot to escape from an area where the pressing has occurred. Accordingly, the invention has an advantage in that it can prevent a function degradation and damage of the self-running robot by changing a running direction of the self-running robot when pressing on the self-running robot is sensed to enable the self-running robot to escape from the area where the pressing has occurred, or notifying, when the pressing cannot be released, a user of the state in voice to take any necessary action.
