  • Publication number: 20190314987
    Abstract: A combined robot and a cruise path generating method thereof includes providing or generating a working map of a self-moving robot and marking a target point on the working map. A planned path is generated according to the location of the target point in the working map. The combined robot begins to walk according to the planned path and it is determined whether an obstacle is encountered during walking. If an obstacle is encountered, a different path adjustment mode is selected according to a relative location when the obstacle is encountered and the planned path is updated according to a walking path to form an actual path. Otherwise, the robot walks directly to form the actual path. The actual path is saved as a cruise path of the combined robot.

  • Publication number: 20190168386
    Abstract: The self-movement robot includes a robot body and a control center disposed on the body. The body includes a first distance sensor disposed in a horizontal direction used to collect two-dimensional map information and a second distance sensor disposed in a vertical direction used to collect spatial height information. While obtaining the two-dimensional map information of a working surface, the control center overlays the spatial height information to the two-dimensional map information and obtains three-dimensional map information of a working region. Through the distance sensors disposed on the self-movement robot, based on the generated two-dimensional map, the spatial height information is overlaid and the three-dimensional map information is generated. In a combined state, the robot invokes and plans a walking path in the working region based on the three-dimensional map, thereby helping to ensure smooth, safe and efficient operation of the combined robot in a complex environment.
