Abstract: A robot cleaner includes a main body, and a wheel unit including a wheel configured to movably support the main body. The wheel unit is installed in a suspension unit and configured to be movable upward or downward. The suspension unit is configured to absorb impact when the wheel unit moves upward or downward, and is installed in a lifting unit coupled to the main body. The suspension unit is configured to be raised or lowered relative to the lifting unit. The lifting unit includes a lifting drive motor including a rotatable shaft disposed in parallel with a direction in which the suspension unit is configured to be raised or lowered, and a transmission unit configured to transmit a rotation force of the lifting drive motor to the suspension unit.

Abstract: Disclosed is a cleaner including a first body having a cleaning unit, a second body configured to move autonomously, and a sensing module including at least one first sensor disposed on the first body and at least one second sensor disposed on the second body, the sensing module sensing a variable distance between the first sensor and the second sensor. Any one of a number of the at least one first sensor and a number of the at least one second sensor is two or more, and the sensing module senses two variable distances by two different combinations of one first sensor and one second sensor. The cleaner further includes a controller configured to control the second body to follow the first body based on the two variable distances.
