The present invention relates to a mobile robot and a method for controlling the same. The present invention provides a mobile robot using the rotational force of at least three rotating members as a movement power source and a method for controlling the same, in which the mobile robot is controlled to effectively travel along a set curved driving path and not deviate from the set curved driving path, or to immediately return to the curved driving path when deviating from the set curved driving path.

Mobile robot and method for controlling same

The present invention relates to a robot cleaner and a method for controlling the same. The present invention provides a mobile robot and a method for controlling the same, the mobile robot using the rotational force of three or more rotary members as a moving power source thereof, wherein the mobile robot is controlled to effectively travel along a configured straight travel route and not to deviate from the configured straight travel route, or is controlled to immediately return to the configured straight travel route when deviating from the configured straight travel route.

Provided is a robot cleaner in which a liquid may be uniformly supplied to a plurality of cleaners and which is easily inspected and repaired in case of defects such as water leakage. The robot cleaner includes a main body portion; a plurality of cleaner fixing portions provided at a lower portion of the main body portion, a plurality of cleaners for wet cleaning being fixed to the plurality of cleaner fixing portions, respectively; a liquid supply portion provided in the main body portion and storing a liquid and supplying the stored liquid to at least one of the plurality of cleaners; a liquid distribution member provided at a lower portion of the main body portion and directly supplying the stored liquid to at least one cleaner of the plurality of cleaners; and a flow path portion providing a movement path of the liquid from the liquid supply portion to the liquid distribution member.

Robot cleaner

Provided are a cleaning robot and a control method thereof. A control method of a cleaning robot using a rotational force of a plurality of rotation members as a motive power source for its driving, includes: driving the cleaning robot by rotating at least one of a first rotation member performing a rotational motion around a first rotation axis and a second rotation member performing a rotational motion around a second rotation axis; determining whether the cleaning robot reaches a wall surface during its driving; and driving the cleaning robot along the wall surface by rotating at least one of the first and second rotation members while maintaining one side surface of the cleaning robot to be in close contact with the wall surface when it is determined that the cleaning robot reaches the wall surface.

Robot cleaner and method for controlling same

A nonvolatile memory device including a memory cell array, a first voltage generator configured to generate a word line operating voltage for each word line of the memory cell array, a second voltage generator configured to generate a bit line operating voltage of the memory cell array, and a temperature unit configured to determine, from a temperature range table, a temperature range for a temperature code according to a real-time temperature of the memory cell array, and to adjust a power supply voltage of the first or second voltage generator based on a selection signal mapped to the determined temperature range.

Non-volatile memory device implementing temperature compensation features

Provided are a cleaning robot and a control method thereof. The control method of the cleaning robot including a first rotation member and a second rotation member each performing a rotational motion around a first rotation axis and a second rotation axis according to the present disclosure includes: obtaining acceleration of the cleaning robot and at least one of rotational loads and rotational speeds of the respective first and second rotation members, during driving of the cleaning robot; determining whether the obtained acceleration is abnormal and whether at least one of the obtained rotational loads or at least one of the obtained rotational speeds is abnormal; and determining that an obstacle is detected when the acceleration is determined to be abnormal and at least one of the rotational loads or at least one of the rotational speeds is determined to be abnormal.

Provided herein is a robot cleaner. The robot cleaner includes a main body, a driving unit provided in the main body and supplying power for traveling of the robot cleaner, first and second rotary members respectively rotating about first and second rotational axes based on power from the driving unit and allowing cleaners for wet cleaning to be fixed thereto, a sensing unit sensing whether a traveling position of the robot cleaner is below an obstacle, and a controller controlling, when it is determined that the traveling position of the robot cleaner is below the obstacle on the basis of a sensing signal from the sensing unit, the driving unit such that the robot cleaner avoids a lower side of the obstacle.

Robot cleaner and method for controlling the same

Provided herein is a robot cleaner. The robot cleaner includes a main body, a driving unit provided in the main body and supplying power for traveling of the robot cleaner, first and second rotary members respectively rotating about first and second rotational axes based on power from the driving unit to provide a movement power source for traveling of the robot cleaner, and allowing cleaners for wet cleaning to respectively be fixed thereto, and a controller determining a cleaning traveling pattern of the robot cleaner and controlling the driving unit such that the robot cleaner travels, while sequentially repeating forward movement and backward movement according to the determined cleaning traveling pattern.
