Abstract: Disclosed are a method for determining a working start point in a movement limit frame of a robot (P) and a method for controlling movement of a robot. The method for determining the working start point includes: setting a limit frame on a map constructed by the robot (P); and selecting, according to an overlap relation between a map area framed by the limit frame and the map constructed by the robot (P), an overlap area for developing a working start point of the robot (P), and determining a center point (O1, O2, O3, O4, O5, O6, O7, O8) of the overlap area which is selected as the working start point in the limit frame of the robot (P); and the limit frame encloses an area for limiting a working range of the robot (P).

Abstract: A method for controlling of obstacle avoidance according to classification of obstacle based on time-of-flight (TOF) camera and cleaning robot are disclosed. The method includes: step 1: a longitudinal height of a target obstacle is calculated and obtained by combining a depth of the target obstacle collected by a TOF camera and intrinsic parameters and extrinsic parameters of the TOF camera, and the target obstacle is identified and classified into a wall-type obstacle, a toy-type obstacle, a doorsill-type obstacle, a sofa-type obstacle or an electric-wire-type obstacle on a basis of a data stability statistical algorithm; and step 2: a deceleration and obstacle avoidance mode or a deceleration and obstacle bypassing mode of a robot is decided according to a classification result, the longitudinal height of the target obstacle of a corresponding type and a trigger situation of a collision warning signal.

Abstract: Disclosed is an environment boundary construction method based on a remote sensor and a mobile robot. The environment boundary construction method includes: step 1, starting the mobile robot, and then controlling the mobile robot to rotate, so as to enable the mobile robot to mark exploration boundaries according to sensed distance information of the remote sensor; step 2, marking a local boundary according to a sensed distance of the remote sensor on the same side surface of the mobile robot when the mobile robot advances in a preset planned direction after the mobile robot completes rotation, where the preset planned direction is selected and configured from directions of all the marked exploration boundaries; and step 3, delimiting environment boundaries of an effective distance measurement area of the mobile robot by the local boundary and the exploration boundaries

Abstract: 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.

Abstract: 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.
