Abstract: Disclosed is a mobile robot including a main body and a pattern irradiation unit emitting a cross-shaped optical pattern including a horizontal line optical pattern and a vertical line optical pattern intersecting the horizontal line optical pattern. The pattern irradiation unit includes a light source and a lens converting light emitted from the light source into the cross-shaped optical pattern, the lens includes convex cells on an incidence surface upon which the emitted light is incident, the incidence surface is divided into a first area converting the light emitted from the light source into the horizontal line optical pattern and a second area converting the light emitted from the light source into the vertical line optical pattern, vertical convex cells extended in parallel in the vertical direction are formed in the first area, and horizontal convex cells extended in parallel in the horizontal direction are formed in the second area.
