This invention provides a collaborative path planning method for ground-based multi-unmanned systems in leader mode. It addresses two scenarios: turning and straight-line movement of the leader node. For turning, a consistency deviation index parameter is introduced to adjust the position of unmanned nodes, implementing a "shortcut" behavior to keep up with the leader node as much as possible while maintaining the basic formation. For straight-line movement, since the leader node and unmanned nodes have the same speed, the algorithm only fine-tunes the angle to reduce formation distance deviation. The autonomous path planning algorithm proposed in this invention, which allows unmanned nodes to follow manned nodes in weak network environments, can adaptively adjust the formation by changing its own direction of travel while maintaining the formation to the greatest extent possible. The planned path is smooth and can meet the special requirements of turning during unmanned system movement.
