  • Patent number: 11042760
    Abstract: The present application provides a mobile robot, a control method and control system of the mobile robot. The control method comprises the following steps: acquiring a depth image obtained through photography of the at least one image acquisition device; wherein, the depth image contains a depth image of the target obstacle; identifying an obstacle type of the target obstacle from the depth image; controlling a navigation movement and/or behavior of the mobile robot based on an acquired positional relationship between the target obstacle and the mobile robot, and the identified obstacle type. In the present application, the type of the target obstacle can be detected effectively, and the behavior of the mobile robot can be controlled based on the detection result correspondingly.

  • Patent number: 10518414
    Abstract: The present application provides a navigation method, a navigation system, a movement control system and a mobile robot. The navigation method comprises the following steps: identifying a target object corresponding to a preset object type label from images captured by the image acquisition device; determining the relative position between the target and the mobile robot based on at least one image which contains the identified target and is captured by the image acquisition device; and generating a map marked with the object type label through marking corresponding preset object type label on a preset map based on the relative position, wherein the map is used for navigating the mobile robot. In the present application, mobile robot can move to the destination position after the destination position contained in the user instruction being identified based on the object type labels on the map, so as to improve human-computer interactivity.
