A cleaning robot includes a machine body, a perception system, a control system, and a driving system; the perception system includes a laser distance sensor and a camera; the laser distance sensor is located on a top surface of the cleaning robot; and the camera is mounted on the cleaning robot through a mounting bracket, and a field of view of the camera includes a traveling direction of the cleaning robot. The camera apparatus is applied to the cleaning robot, and provides good shockproof performance and good stability. In addition, when a distance between optical axes of two cameras changes, the camera can be replaced and calibrated at any time, facilitating maintenance and repair.
