A method for a robot to judge whether the robot collides with a virtual wall, and a chip and the intelligent robot. The method comprises: providing pre-judgement regions on two sides of a virtual wall, so that when entering the pre-judgement regions, the robot can judge whether the robot collides with the virtual wall by combining a current direction of the robot as well as a relationship between a straight-line distance from the robot to a reference point and a straight-line distance from the reference point to a center point of the virtual wall.

Method for robot to judging whether the robot collides with virtual wall, chip and intelligent robot

A control method for carpet drift in robot motion, a chip, and a cleaning robot are disclosed. The control method includes: performing fusion calculation on a current position coordinate of the robot according to data sensed by a sensor every first preset time, calculating amount of drift, relative to a preset direction, of the robot, according to a relative position relationship between a current position and an initial position of the robot, and accumulating to obtain a drift statistical value; and calculating the number of acquisitions of the position coordinate within a second preset time, averaging to obtain a drift average value, determining a state of the robot deviating from the preset direction according to the drift average value, and setting a corresponding Proportion Integration Differentiation (PID) proportionality coefficient to synchronously adjust speeds of left and right drive wheels of the robot while reducing a deviation angle of the robot.
