Problems solved by technology

Compared with the virtual wall transmitter, this method saves hardware costs. However, due to walking errors and other reasons, the robot cannot accurately detect the virtual wall, which affects the blocking effect of the virtual wall.

Abstract

The invention relates to a method for judging whether a robot collides with a virtual wall or not, a chip and an intelligent robot. Pre-judging areas are arranged on the two sides of the virtual wallso that when the robot enters the pre-judging areas, whether the robot collides with the virtual wall or not can be accurately judged with the combination of the current direction of the robot and therelation between the straight line distance between the robot and a contrast point and the straight line distance between the contrast point and the center point of the virtual wall, the judgment isnot likely to be subjected to external environment interference, the misjudgement condition is avoided, and accuracy is very high.

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...
