Abstract: In order to solve the problem of motion planning with dynamics, RRT algorithm was proposed. But with the environment becoming complex, the tree exploration slows down significantly. In this paper, a novel two-stage motion planning is proposed. The first stage is discrete search based on the scent pervasion principle, and the second stage is the sampling-based motion planning under the direction of the scent information. The results show the good performance and convergence speed of the proposed algorithm.
Keywords: RRT; rapidly-exploring random tree; two-stage motion planning; sampling-based motion planning; robot path planning; scent pervasion.
