Description

Technical Field

[0002] Robot is the common name for automatic control machines, which include all machines that simulate human behavior or thoughts and simulate other creatures (such as robot dogs, robot cats, etc.). In a narrow sense, there are many classifications and controversies about the definition of robots. Some computer programs are even called robots. In contemporary industry, robots refer to man-made machine devices that can automatically perform tasks to replace or assist human work;

[0003] When the robot's battery is low, it will automatically look for a power source for charging. When the robot automatically moves to the power source, it will automatically dock with the plug for charging. However, the robot's wheels can still rotate and can easily move due to external forces, causing the charging to be disconnected, affecting the charging process. To address the above problems, this application designs a movable automatic charging robot. Utility Model Content
