Path planning for mobile machine in large scale navigation disclosed. A path for moving a mobile machine is planned by: determining a start map node in a map graph based on a start point in the path and a goal map node in the map graph based on a goal point in the path; determining whether the start map node and the goal map node correspond to the same submap; and if so, planning the path between the start point and the goal point using a real-time path planning method; otherwise, obtaining the path between the start point and the goal point by merging a node path between the start map node and the goal map node, a first real-time path between the start point and a first stop point, and a second real-time path between the goal point and a last stop point.

Path planning for mobile machine in large scale navigation

According to one aspect of the present disclosure, a method of multi-robot fleet control by a network device is provided. The method may include estimating a path to a final target for a robot. The method may include determining whether the robot will traverse a crossing region based on the path to the final target. The method may include, in response to determining that the robot will traverse the crossing region, updating a stop list for the robot to include a stop point for the crossing region. The method may include causing the robot to move to and stop at the stop point for the crossing region until any other robot in the multi-robot fleet arriving at the crossing region prior to the robot has cleared the crossing region. The method may include causing the robot to move to and stop at the emergency stop line during an emergency-operation mode.
