PROBLEM TO BE SOLVED: To provide an obstacle sensing module capable of sensing a surrounding obstacle and provide a cleaning robot provided with it.SOLUTION: An obstacle sensing module includes a reflection mirror 121a for generating reflection light by reflecting again planer light reflected by an obstacle, an optical lens 122a spaced apart from the reflection mirror 121a by a predetermined distance to cause the reflection light to pass through it, an image sensor 123a for receiving the reflection light passed through the optical lens 122a to generate an electrical image signal, and a light receiving part 120a having a signal processing circuit for receiving the electrical image signal and converting it into a digital electrical image signal, and thus a uniform planer light can be formed, a degree of accuracy in sensing an obstacle can be improved and the obstacle present around the module can be sensed by using the planer light, so that an economical efficiency and a structural efficiency can also be improved without necessity for installing a plurality of sensors or installing another servo-mechanism. |
