Abstract
A mobile robot of the present disclosure includes a first pattern emission unit configured to emit a first patterned light downward and forward from the main body on a floor of an area to be cleaned; and an image acquisition unit configured to acquire an image of first patterned light emitted by the first pattern emission unit and incident on an obstacle. A pattern is detected from the acquired image to determine an obstacle, and a cliff is detected based on at least one of a shape or a position of the pattern in the image. The mobile robot may identify a travel path that does not lead to the cliff.
