A moving robot includes: a main body; a traveling unit configured to rotate and move the main body; a sensing unit configured to sense position information of a specific point of a front portion of a docking device; and a controller configured to, based on sensing result of the sensing unit, determine i) whether a first condition, which is preset to be satisfied when the docking device is disposed in a front of the moving robot, is satisfied, and ii) whether a second condition, which is preset to be satisfied when the moving robot is disposed in a front of the moving robot, is satisfied, to control an operation of the traveling unit so as to satisfy the first condition and the second condition, and to move to the front so as to attempt to dock in a state where the first condition and the second condition are satisfied.

Moving robot and controlling method for the moving robot

A cleaner includes a cleaner body, a power supply including a first battery and a second battery that are accommodated in the cleaner body, and a power supply circuit configured to operate in a charge mode for receiving power from the outside to recharge the first and second batteries or in a discharge mode for supplying the power recharged in the first and second batteries to a load, a charging terminal connected to an external charging stand and configured to supply direct current (DC) power to the first and second batteries in the charge mode, and a controller configured to control an operation of the power supply in the discharge mode and the charge mode.

Cleaner

Disclosed is a cleaner including a first body having a cleaning unit, a second body configured to move autonomously, and a sensing module including at least one first sensor disposed on the first body and at least one second sensor disposed on the second body, the sensing module sensing a variable distance between the first sensor and the second sensor. Any one of a number of the at least one first sensor and a number of the at least one second sensor is two or more, and the sensing module senses two variable distances by two different combinations of one first sensor and one second sensor. The cleaner further includes a controller configured to control the second body to follow the first body based on the two variable distances.

The present disclosure discloses a robot cleaner, including a cleaner body; and a sensing unit disposed in the cleaner body, wherein the sensing unit includes a rotating body configured to be horizontally rotatable around a rotation shaft passing through an inside of the cleaner body; a sensing unit mounted on one side of the rotating body to sense a feature or an obstacle in the vicinity of the cleaner body; and a tilting unit installed inside the rotating body to vertically tilt the sensing unit.

Robot cleaner

A robot cleaner includes a main body, a light transmitting unit, an image sensor, a base, a rotation drive unit, a tilting unit, and a tilting drive unit. The light transmitting unit emits light. The light emitted from the light transmitting unit and reflected or scattered is formed on the image sensor. The base supports the light transmitting unit and the image sensor and is rotatably disposed in the main body. The rotation drive unit rotates the base. The tilting unit tilts the light transmitting unit and the image sensor.
