There is provided a mobile robot that performs the obstacle avoidance, positioning and object recognition according to image frames captured by the same optical sensor. The mobile robot includes an optical sensor, a light emitting diode, a laser diode and a processor. The processor identifies an obstacle and a distance thereof according to image frames captured by the optical sensor when the laser diode is emitting light. The processor further performs the positioning and object recognition according to image frames captured by the optical sensor when the light emitting diode is emitting light.

An auto clean machine comprising: a height computing device; and an obstacle determining device. The height computing device is turned on to compute a height or an overhang height of an obstacle when the obstacle determining device determines the obstacle exists in a predetermined region of the auto clean machine. The height computing device does not compute the height and the overhang height when the obstacle determining device does not determine the obstacle exists in the predetermined region.

A robot cleaner according to the present invention includes a body provided with a driving unit for movement, a position recognition unit provided in the body to recognize a position of the body, a storage unit configured to store, on a map, a region cleaned while the body is moving by the driving unit, and a control unit configured to control the driving unit, wherein the control unit determines whether a charging stand exists in a cleaning completed region on the map stored in the storage unit when a return condition that the body returns to the charging stand is satisfied, searches for an uncleaned region when the charging stand is not located in the cleaning completed region, and controls the driving unit such that the body moves from a current position to a point in a found uncleaned region or a point around the found uncleaned region.

A work vehicle comprising: a drive wheel unit that is provided in a vehicle body and is configured to be driven by a travel drive mechanism; a work unit that is provided in the vehicle body and is configured to perform work on a work target; a battery provided in the vehicle body; a motor that is configured to receive electric power from the battery and drive the work unit; an inclination sensor configured to detect an inclination of the vehicle body relative to a horizontal plane; and a first captured image acquisition unit configured to acquire a captured image that shows surroundings of the vehicle body when the work is being performed.

Provided is a robot cleaner. The artificial intelligence robot cleaner includes a traveling driving unit configured to allow the artificial intelligence robot cleaner to travel in an indoor space of a home, a cleaning unit configured to remove pollutants, a sensor configured to acquire data that is used to identify a plurality of members, and a processor configured to control the traveling driving unit and the cleaning unit so as to determine one or more subordinate spaces corresponding to each of the plurality of members among a plurality of subordinate spaces by using the data and a map of the indoor space, determine a return time of some or all of the plurality of members, determine a cleaning priority of the plurality of subordinate spaces based on the return time, and perform cleaning according to the cleaning priority.

The present disclosure provides a surface cleaning apparatus that mechanically removes liquid and debris from a brushroll and stores the mechanically-removed liquid and debris onboard the apparatus in a first collection area. The surface cleaning apparatus also collects further liquid and debris from the brushroll by a source of suction including a vacuum motor or a pump and stores the collected liquid and debris onboard the apparatus in a second collection area.

A cleaning robot includes a machine body, a perception system, a control system, and a driving system; the perception system includes a laser distance sensor and a camera; the laser distance sensor is located on a top surface of the cleaning robot; and the camera is mounted on the cleaning robot through a mounting bracket, and a field of view of the camera includes a traveling direction of the cleaning robot. The camera apparatus is applied to the cleaning robot, and provides good shockproof performance and good stability. In addition, when a distance between optical axes of two cameras changes, the camera can be replaced and calibrated at any time, facilitating maintenance and repair.

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.

The present invention relates to a robot vacuum cleaner comprising sub-wheels having variable rotational positions, the robot vacuum cleaner comprising subframes rotatably attached to main frames to ground the sub-wheels when in a constrained state.
