A robot cleaner including: a cleaner body; a motor, configured to be fixed to the cleaner body, and provide a rotational force; a gear unit configured to transmit the rotational force of the motor; a wheel configured to rotate and drive the cleaner body according to the rotational force of the motor transmitted by the gear unit to the wheel; and a suspension including a first end portion pivotally supportable on a pivot of the cleaner body, which is spaced apart from a rotary shaft of the motor, and a second end portion to extend from the first end portion and support the wheel to move up and down with respect to the cleaner body as the second end portion moves in a first direction and a second direction around the pivot of the cleaner body.

Robot cleaner

Provided are a driving robot apparatus including a rotatable holder to which a cleaning pad is fixable, a method of controlling the driving robot apparatus, and a computer-readable recording medium having recorded thereon a computer program. The method of controlling the driving robot apparatus includes rotating the holder with a cleaning pad fixed to the holder; emitting light through an opening in the holder to a surface of the cleaning pad fixed to the holder while the holder is rotating, the surface of the cleaning pad including two or more reflective areas having different light reflectivities from each other; receiving reflected light reflected from the surface of the cleaning pad through the opening in the holder while the holder is rotating; and identifying the cleaning pad based on the received reflected light.

Driving robot apparatus, control method of the driving robot apparatus, and recording medium having recorded thereon computer program

A cleaning robot is provided. The cleaning robot includes a body, a light detection and ranging (LiDAR) module having a LiDAR sensor rotatably supported by the body, a light-emitting display module mounted on the LiDAR module, wherein the light-emitting display module is configured to display an image based on an afterimage effect according to a rotation of the LiDAR module.

Cleaning robot

Disclosed is a cleaner. The cleaner according to an embodiment includes a main body, a suction device configured to suck dust outside the cleaner, a dust detection sensor including a light emitting element and a light receiving element disposed adjacent to the suction device, a dust container configured to store sucked dust through the suction device, and a processor configured to identify a dust inflow state and a dust amount of the dust container based on a voltage value output from the light receiving element, and control an operation of the cleaner based on the identified dust inflow state and dust amount, wherein the light emitting element and the light receiving element are disposed at an outside of the dust container in a direction toward an inlet of the dust container.

Cleaner and control method thereof

The disclosure relates to a moving apparatus for cleaning, a collaborative cleaning system, and a method of controlling the same, the moving apparatus for cleaning including: a cleaner configured to perform cleaning; a traveler configured to move the moving apparatus; a communicator configured to communicate with an external apparatus; and a processor configured to identify an individual cleaning region corresponding to the moving apparatus among a plurality of individual cleaning regions assigned to the moving apparatus and at least one different moving apparatus based on current locations throughout a whole cleaning region, based on information received through the communicator, and control the traveler and the cleaner to travel and clean the identified individual cleaning region. Thus, the individual cleaning regions are assigned based on the location information about the plurality of cleaning robots, and a collaborative clean is efficiently carried out with a total shortened cleaning time.

Moving apparatus for cleaning, collaborative cleaning system, and method of controlling the same

A robot cleaner is provided. The robot cleaner includes a three-dimensional image sensor, an optical sensor, a gyro sensor, and at least one processor configured to control a driving state of the robot cleaner based on image data acquired by the three-dimensional image sensor, optical data acquired by the optical sensor, and angular velocity data acquired by the gyro sensor, wherein the three-dimensional image sensor and the optical sensor are respectively arranged to be tilted by a predetermined tilting angle, and a tilting angle of the three-dimensional image sensor is smaller than a tilting angle of the optical sensor.

Robot cleaner and controlling method thereof

Highly efficient thermoelectric materials with an improved thermoelectric performance due to doping ions on a Bi&#x2014;Se&#x2014;Te based compound, and a thermoelectric element and a thermoelectric module including the same are disclosed. The thermoelectric materials include a compound expressed by Chemical Formula 1 or a compound expressed by Chemical Formula 2.(AB)(BiSeTe)&#x2003;&#x2003;&#x3c;Chemical Formula 1&#x3e; In Chemical Formula 1, A is a divalent cation element, B is a monovalent anion element, A and B are different with each other, and x is in a range of 0.0&#x3c;x&#x2264;0.4.(AB)(BiSeTe)&#x2003;&#x2003;&#x3c;Chemical Formula 2&#x3e; In Chemical Formula 2, A is a monovalent cation element, B is a monovalent anion element, A and B are different with each other, and x is in a range of 0.0&#x3c;x&#x2264;0.4.
