Abstract:

Aiming at the coverage search problem of unmanned surface vessel (USV) cluster in unknown environment, an auction collaborate frontier algorithm is proposed. Firstly, the map detection boundary is extracted according to the idea of boundary exploration. Secondly, the task interval is divided by the improved K-means++ clustering algorithm based on the idea of hierarchical clustering to eliminate unsafe or low-yielding target search points. Finally, the search task is dynamically assigned to the USV cluster by the distributed bidding algorithm to maximize the cluster search efficiency, and each boat goes through multiple rounds of assignment and executes the search task until the whole water is covered. Simulation results show that the algorithm takes less time for the task and the total distance travelled by the cluster compared to several boundary exploration algorithms without collaboration at the same cluster size, and the coverage search efficiency improves with increasing USV cluster size at the same task map.

Key words: cluster collaboration, frontier exploration, task assignment, path planning
