  • Patent number: 11014236
    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.
