Robot movement control method, system and robot

 [0001] The present invention relates to the field of robot technology, and in particular, to a robot movement control method, system, and robot.

 Background technique

 [0002] With the continuous development of technology, clean robot products have entered thousands of households, bringing great convenience to users. However, during the home cleaning process, due to various factors, there are situations in which some users do not want the robot to enter. In order to solve this problem, the virtual wall method is used to limit the moving area of the robot, and a virtual wall is set as a limited area in the area where the robot is not required to enter, so that the robot can avoid the limited area.

 [0003] The existing virtual wall solutions are all implemented by providing a certain trigger signal. When the cleaning robot receives the trigger signal, the corresponding action is performed to avoid entering the limited area. Commonly used trigger signals are: Magnetic field signals, which are the most common processing method by laying magnetic strips on the ground as virtual walls; infrared signals, which are emitted by one or more infrared emitting devices as virtual walls.

 [0004] Although the existing robot movement control scheme realizes the limitation of the moving area of the robot, it is necessary to additionally add sensors (such as magnetic field sensors, infrared sensors, etc.) and corresponding triggering devices (such as magnetic strips, infrared emitting devices, etc.). The implementation cost is greatly increased. At the same time, if the user needs to adjust the limited area, the trigger device must be manually moved, which is troublesome, and the remote control cannot be performed in this case, which limits the use scenario.

 [0005] In summary, the existing robot mobile control scheme has higher cost, less flexibility, and poor user experience.
