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.
Abstract:
A cleaning robot may have a body, a moving unit provided on the body to move the body in a cleaning space, a cleaning unit provided on the body to clean a floor of the cleaning space, a floor image obtaining unit configured to obtain a floor image of the cleaning space, and a control unit configured to determine if foreign substance is present on the floor of the cleaning space based on the floor image, and control the moving unit to move the body to a position of the foreign substance, in which the cleaning robot, by obtaining an image of a floor to be cleaned, detects the foreign substance that is not positioned on a moving track of the cleaning robot, and when the foreign substance is detected, moves to the position of the foreign substance to perform a cleaning.
