The present disclosure relates to a robot cleaner including a coupler provided on a rotary plate to disperse stress generated by a load and stress generated by a rotation, and the robot cleaner includes a rotary plate having a lower portion to which a mop facing a floor is coupled, the rotary plate being rotatably coupled to a body, and a coupler coupled between the body and the rotary plate, thereby preventing damage to the rotary plate by dispersing the stress generated by the load and the stress generated by the rotation.

Robot vacuum

Disclosed is a robot cleaner including: a main body forming an outer shape; a pair of rotary mops moving the main body while rotating in contact with a floor; a drive motor rotating the pair of rotary mops; a pump connected to a water tank and driving a nozzle for spraying water to the rotary mop; and a controller for determining water content of the rotary mop in a preliminary step before wet cleaning, and controlling to start the wet cleaning after driving the pump until the water content of the rotary mop satisfy a certain level. Accordingly, it is possible to detect a change in the output current of the motor of the rotary mop of the robot cleaner and determine the water content according to the change in the current value.

AI robot cleaner and robot system having the same

A mobile robot is disclosed, including a body, a mop module installed on the body and being configured to clean using water, a water tank removably disposed in the body and being configured to store water to be supplied to the mop module, and a detachable water tank module installed on the water tank. The water-tank detachable module includes a hook engaged with or coupled to the body and an operation button disposed on a surface of the water tank to operate the hook.

Cleaner

The present disclosure relates to a mobile robot, including: a mop module having a pair of spin mops, which rotate clockwise or counter-clockwise, and a mop motor configured to provide a driving force to the pair of spin mops; a sweep module disposed forward of and spaced apart from the mop module, and having a collecting part, which forms a collecting space to store foreign materials, a sweeping part configured to introduce foreign materials into the collecting space while rotating, and a sweeping motor configured to provide a driving force to the sweeping part; a body, on which the mop module and the sweep module are disposed; and a first floor sensor disposed forward of the sweep module, and configured to sense reflectance of light reflected from a floor.

Mobile robot

The present disclosure discloses that the robot cleaner includes a mop module including a left rotating plate to which a mop is attached to the bottom surface and a right rotating plate to which the mop is attached to the bottom surface; a base on which the mop module is installed; a case disposed to cover at least an upper portion and a part of a side of the base; and a plurality of push supporters supporting the case spaced apart from the base, wherein each push supporter provides the case with the elastic restoring force at least in the upper direction of the base and the outer direction of the base.

The present disclosure relates to a docking apparatus for a mobile robot including a sterilization unit, which emits germicidal light to a floor cloth to sterilize the floor cloth, and which includes: a germicidal lamp which vertically overlaps with the floor cloth of the mobile robot, and emits the germicidal light to a front end thereof; a diffusing part for diffusing the germicidal light to a rear end of the germicidal lamp; and a converging part for converging the germicidal light to a rear end of the diffusing part.

Docking apparatus for mobile robot

A center of gravity of a mobile cleaning robot may be positioned on an imaginary central longitudinal axis of the mobile robot. The center of gravity of the mobile robot may be positioned at a front side of an imaginary central horizontal line connecting spin rotation axes of left and right spin mops of the mobile robot. The center of gravity of the mobile robot may also be positioned at a front side of a center of gravity of a battery and a center of gravity of a water tank, and at a rear side of a center of gravity of a sweep module of the mobile robot.

The present disclosure relates to a mobile robot, and more particularly to a mobile robot, including: a bumper which surrounds at least a portion of an outer circumference of the body; position restoring modules having an elastic member and disposed to be symmetrical to each other; a bumper guide module, having a guide hole and a protruding guider which moves inside the guide hole; and impact sensing modules configured to sense impact and disposed to be symmetrical to each other.

Disclosed is a mobile robot including a body, a rotating plate rotatably installed on the body and having a lower surface where a mop portion is attached, and an attachment guider installed on the lower surface of the rotating plate to guide an attachment position of the mop portion. The attachment guider includes a guide rim and a plurality of elastic pieces. The guide rim is disposed to surround a rotation axis of the rotating plate. The plurality of elastic pieces extend from the guide rim in a direction toward the rotation axis, have a free end protruding to a lower side or downward than the guide rim, and are spaced apart from each other along a circumference of the guide rim.
