Hello, please confirm whether the location of the virtual wall is a scene where the robot is difficult to walk, such as sliding door slides, high and low steps, etc. When the robot is cleaning such scenes, it may be difficult to walk, and the robot may perform an escape action. If the virtual wall is set here, it will easily cause the robot to cross the virtual wall by mistake. It is recommended that you adjust the position of the virtual wall appropriately when drawing the virtual wall, and draw such scenes outside the virtual wall to prevent the robot from walking on such scenes.
