Path planning of mobile robot with PSO-based APF and fuzzy-based DWA subject to moving obstacles

Abstract: This paper proposes a two-layer path-planning method, where an optimized artificial potential field (APF) method and an improved dynamic window approach (DWA) are used at the global and local layer, respectively. This method enables the robot to plan a better path under a multi-obstacle environment while avoiding the moving obstacles effectively. For the part of global path planning, a new repulsive field is proposed based on the APF method. The length and smoothness of the global path are taken as fitness fun… Show more

“…In contrast to most studies, the evaluation coefficients of the robot are adaptively adjusted according to the sea state, where the weights of velocity are reduced and the weights of distance are increased, as the sea state is poor; for example. Lin et al [20] proposed a two-layer path-planning method based on the improved APF for global path planning and the enhanced DWA with fuzzy control for local path planning. The collision-risk index and relative distance of the robot and the obstacle are considered to dynamically adjust the weights of the evaluation function and finally obtain a reasonable motion path.…”

“…After velocity space search and sampling, DWA generates predicted motion trajectories for the robot within Ns based on the sampled multiple sets of velocity (v, ω) simulations and then scores each trajectory according to the appropriate objective function. The part of traditional DWA contains three evaluation functions, velocity, heading, and dist, as shown in Equation (20).…”

“…Even though DWA has outstanding performance in dynamic environment, the response to moving obstacles and the weight coefficients of subfunctions are still worth being optimized. So as to acquire better weight coefficients, fuzzy control was applied to DWA evaluating the danger level of collision risk index and relative distance, 18 where the mobile robot can instantly turn to avoid high-speed obstacles in overtaking condition. Besides, Chang et al 19 proposed an improved DWA based on Q-learning to balance the effectiveness and speed whose evaluation functions were also extended by adding historical trajectory information.…”

“…In previous studies, researchers mainly considered using different algorithms to solve the path planning problem of mobile robots without collision: for example, the A* algorithm [ 5 , 6 ], RRT algorithm [ 7 , 8 ], Dijkstra algorithm [ 9 , 10 ], and artificial potential field method (APF) [ 11 , 12 ] and so on.…”
