Title: ROBOT AND ROBOT CONTROL METHOD
Abstract:
A cleaning robot (10), comprising: a control unit. The control unit is configured so as to perform the following: identifying, on the basis of a signal threshold and a virtual wall signal detected by a detection component, a virtual wall; adjusting, when the virtual wall is identified, the signal threshold; and controlling, on the basis of the adjusted signal threshold and the virtual wall signal, the robot to move along an exterior side of the virtual wall and to keep a drive wheel of the robot at the exterior side of the virtual wall. A robot controlling method is also provided. The method resolves the issue of a robot being unable to fully automatically complete a cleaning task in a complex environment without user intervention as a result of a drive wheel of the robot crossing over to an interior side of a virtual wall due to only setting a high signal threshold, or as a result of an error due to only setting a low signal threshold. The invention achieves, on the basis of accurate identification of a virtual wall, the effect of keeping a drive wheel of a robot at an exterior side of the virtual wall and not entering into an interior area within the virtual wall when the robot moves along the exterior side of the virtual wall.
