Abstract
Disclosed herein are an obstacle sensing module and a cleaning robot including the same. The cleaning robot includes a body, a driver to drive the body, an obstacle sensing module to sense an obstacle present around the body, and a control unit to control the driver, based on sensed results of the obstacle sensing module. The obstacle sensing module includes at least one light emitter including a light source, and a wide-angle lens to refract or reflect light from the light source so as to diffuse the incident light in the form of planar light, and a light receiver including a reflection mirror to again reflect reflection light reflected by the obstacle so as to generate reflection light, an optical lens spaced from the reflection mirror by a predetermined distance, to allow the reflection light to pass through the optical lens, and an image sensor, and an image processing circuit.
