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.

Abstract: A robot cleaner includes a main body, a light transmitting unit, an image sensor, a base, a rotation drive unit, a tilting unit, and a tilting drive unit. The light transmitting unit emits light. The light emitted from the light transmitting unit and reflected or scattered is formed on the image sensor. The base supports the light transmitting unit and the image sensor and is rotatably disposed in the main body. The rotation drive unit rotates the base. The tilting unit tilts the light transmitting unit and the image sensor.
