[0002] With the improvement of people's living standards, keeping pets has gradually become a fashion. However, due to the working hours of pet owners who go out early and come back late, there are more and more problems caused by pets being left alone at home: 1. Pets are left alone at home without anyone to accompany them, which is prone to psychological problems; 2. When pets feel hungry at home, pet owners cannot feed them in time; 3. Pets excrete feces, and pet owners cannot clean them up in time, causing bad smells at home.

[0003] Therefore, various intelligent pet-care robots have emerged on the market to solve these problems. To realize these functions, robots need a variety of detection devices, such as visual sensors, taste sensors, displacement sensors, etc. The detection devices of existing robots are usually fixedly installed on specific parts of the robots to detect areas within a specific range. Therefore, the detection range of the robot detection device is fixed and has certain limitations, and it cannot perform better detection of the surrounding environment. Utility Model Content
