Abstract: The disclosure relates to a video monitoring method for mobile robot. The method includes the following steps: providing one or more private area on a basis of a map constructed by a mobile robot; determining, on a basis of a position of the mobile robot and an image shot from a shooting angle of a camera, whether an image shot currently contains private contents; if the image shot currently contains private contents, shielding the private contents contained in the image; and if the image shot currently is not containing private contents, continuing monitoring the mobile robot. By providing one or more private area in a map constructed by a mobile robot, the mobile robot can determine whether a shot image contains private contents during the subsequent video monitoring process, so as to shield the private contents in the image, thereby ensuring the security in video monitoring of the mobile robot, and avoiding privacy leakage.

Abstract: Disclosed are a method for dividing a robot area based on boundaries, a chip and a robot. The method includes: setting, when the robot travels along the boundaries in a preset boundary direction in an indoor working area, a reference division boundary line according to data scanned by a laser sensor of the robot in real time; and identifying, after the robot finishes traveling along the boundaries in the preset boundary direction, a door at a position of the reference division boundary line according to image characteristic information of the position of the reference division boundary line acquired by a camera of the robot, and marking the reference division boundary line on a laser map, so as to divide the indoor working area into different room subareas by means of the door.

Abstract: A method for correcting a determination threshold of a floor medium and a method of detecting thereof are provided. The method is used for controlling a mobile robot equipped with a sound emitter and a sound receiver to detect and recognize the floor medium during a movement just started. A first detection result of a current floor medium is obtained by actively transmitting and receiving a sound signal, then, a to-be-adjusted detection result of the current floor medium is obtained only by passively receiving the sound signal through the sound receiver, and according to the similarity/difference of the two detection results, the determination threshold is corrected in the case of passively receiving the sound signal, so that the to-be-adjusted detection result is determined to be consistent with the first detection result.

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 method for controlling a motion of a robot based on map prediction mainly carries out estimation and calculation for a wall surface by combining an external sensor with internal map information about a robot, so as at least to enable the robot to walk along the estimated wall surface. The method for controlling the motion of the robot based on map prediction can be adapted to various different wall surfaces based on map prediction, including different colors and shapes, thereby reducing an operation time; and the accuracy of map prediction can be continuously corrected during an operation process, thereby realizing a good wall-following behavior.

Abstract: The present disclosure relates to a method for straight edge detection by a robot and a method for reference wall edge selection by a cleaning robot. The method for straight edge detection by the robot includes that: position coordinates of detection points are determined according to distance values detected by a distance sensor of the robot and angle values detected by an angle sensor of the robot, and then a final straight edge is determined according to a slope of a straight line formed by adjacent two of the detection points.

Abstract: A map update control method and a map update control system for a vision robot are disclosed. The map update control method includes the following steps: S1, measured data of the map attributes is acquired; S2, when it is detected that the vision robot completes a traversal of the preset working region, whether the current map and a prestored historical map meet a preset matching degree is judged according to the map attribute measured data, in a case that the current map and the prestored historical map meet the preset matching degree, it is determined to store the current map; and S3, when it is determined to store information of the map attributes corresponding to the current map, the information of the map attributes corresponding to the current map is written in a map storage medium, to update information of the map attributes corresponding to the historical map.
