Abstract

The invention relates to a method and a chip for judging whether a robot collides with a virtual wall and an intelligent robot. By setting a pre-judgment area on both sides of the virtual wall, when the robot enters the pre-judgment area, it combines the current direction of the robot and the robot and the comparison point. The relationship between the straight-line distance and the straight-line distance between the control point and the center point of the virtual wall can accurately determine whether the robot collides with the virtual wall, it is not easily disturbed by the external environment, and there is no misjudgment. .

Description

technical field [0001] The invention relates to the field of intelligent robots, in particular to a method for judging whether a robot collides with a virtual wall, a chip and an intelligent robot. Background technique [0002] Existing sweeping robots, in order to prevent them from straying into some areas that do not need to be cleaned, generally set a virtual wall transmitter at the entrance of the area, and the virtual wall transmitter will generate an infrared signal. When the robot detects the infrared signal , stop moving forward, thus preventing the robot from entering the area. This method needs to provide an additional virtual wall transmitter, which increases the hardware cost. At present, some manufacturers adopt the method of setting up virtual walls, and draw a virtual line at the entrance of the area that does not need to be cleaned corresponding to the map constructed by the robot. Set the corresponding position as the virtual wall, and when the robot moves...
