Abstract
In order to successfully complete the exploration mission on moon surface, it’s necessary to choose a suitable probe point to plan a feasible path for lunar rover. In this paper, a probe point selection strategy is presented. The proposed strategy consists of the following three steps: Firstly, the feasible region on a given terrain map is generated by Breadth-first search algorithm based on rover travers ability; secondly, the evaluation cost of the probe point is constructed by geography information and light condition; finally, an optimal point that satisfies the constraint is selected by particle swarm optimization (PSO). In order to verify that the selected probe point can be safely arrived, the path of the rover is planned by A* algorithm. The experimental results show the correctness and feasibility of the proposed probe point selection strategy.
