Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a pet companion robot. Background Art

[0002] Nowadays, people living in big cities are working in the 996 mode, and the pace of life is constantly accelerating. Working day after day makes us feel boring, and gradually keeping pets at home has become a part of our daily fun. But problems also arise, because pet owners work early and come back late, and pets are left alone at home, which makes them feel lonely and have psychological problems. In addition, pet owners sometimes cannot observe the pets' situation at any time through the surveillance at home.

[0003] In order to solve the above problems, pet owners usually choose to install mobile robots at home. When they are outside, they can control the robot to move indoors and play with pets or observe the pets through cameras through mobile phone apps. However, the cameras of existing robots are always exposed to the outside, and the presence of cameras may cause privacy leakage. In addition, the motion components of existing robots are usually set at the bottom of the robot shell. Since the distance between the robot shell and the bottom surface is small, the robot will fall backwards when crossing places with large height differences such as door sills and pressure strips. This means that the robot can only move on some flat ground, and the practicality of the robot is low. Utility Model Content
