Sensor module and mobile cleaning robot

Abstract

The invention discloses a sensor module, and the module comprises a camera module which comprises an optical range camera, a plurality of illumination elements disposed around the optical range camera, and a circuit board which is electrically connected with the optical range camera and the illumination elements; a first mounting seat, provided with a limiting hole used for limiting the position of the optical range camera and a first limiting part arranged on the periphery of the limiting hole and used for limiting the position of the illumination element. The illumination element is limitedby the first limiting part to enable the included angle between the optical axis of each illumination element and the optical axis of the optical range camera to be an acute angle. The invention further discloses a mobile cleaning robot. The mobile cleaning robot comprises a robot body and the sensor module. The relative fixation of the optical range camera and each illumination element is realized, the change of the relative position between the camera and the illumination element in the assembly process is avoided, and the optical range camera can clearly and accurately capture the image ofthe to-be-tracked surface.

Description

technical field [0001] The application belongs to the technical field of cleaning appliances, and in particular relates to a sensor module and a mobile cleaning robot. Background technique [0002] A mobile robot is a machine device that performs work automatically. It can accept human commands, run pre-programmed programs, and act according to instructions formulated with artificial intelligence technology. Therefore, it has strong self-organization, autonomous operation, and autonomous planning. ability. Mobile robots can be used indoors or outdoors, in industry or at home, can be used to replace security patrols, replace people to clean the ground, and can also be used for family companionship, office assistance, etc., such as medical robots, military robots, disabled robots, patrol robots, cleaning More and more robots are appearing in the public's field of vision. [0003] With the update and iteration of mobile robot mobile technology, VSLAM (Visual Simultaneous Loca...

Problems solved by technology

[0006] During the assembly process, due to the interference of other surrounding components, the soldered LEDs are easy to change the angle of each LED, making it deviate from the original set angle, and cannot provide the expected illumination for the telecentric lens, resulting in the telecentric lens Inability to clearly capture images of tracking surfaces;

[0007] The telecentric lens and each of the LEDs are respectively mounted on different mounting structures, and different mounting structures have different processing errors in the process of processing, and the telecentric lens and each o
