  • MOBILE ROBOT AND OPERATION METHOD THEREOF
    Publication number: 20240069566
    Abstract: A mobile robot and an operating method thereof are provided. The mobile robot periodically removes foreign substances stuck on casters. To this end, while the mobile robot is traveling using a wheel module including a plurality of drive wheels and casters, a nearby mat area is detected using a sensor in response to recognition that a caster management mode has been started. After the mobile robot moves to be located on the detected mat area, the mobile robot performs predetermined motion driving to remove contaminants on the casters without departing from the mat area. This can minimize damage, such as scratches, on a floor due to foreign substances stuck on the casters while the mobile robot travels.
