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.

Robot vacuum cleaner

A moving robot includes a main body, a drive assembly moving the main body, and a cleaner head performing cleaning on a cleaning area in which the main body is positioned, wherein the drive assembly includes a plurality of pulleys, a motor connected to any one of the plurality of pulleys and generating a driving force, a belt rotated in contact with the plurality of pulleys, and a support shaft connected to some of the plurality of pulleys and changing a position of the pulley such that an area in which the belt is in contact with a ground or an obstacle is maintained to be equal to or greater than a reference area.

Moving robot and control method thereof

A moving robot includes a main body, a drive assembly moving the main body, and a cleaner head performing cleaning on a cleaning area in which the main body is positioned, wherein the drive assembly includes a main wheel, a motor generating a driving force, a gear box connected to the main wheel and the motor and transferring the driving force from the motor to the main wheel, and a leg member disposed on a shaft connecting the main wheel and the gear box and providing thrust independently of the main wheel.
