一种用于Mecanum底盘的自适应路径规划算法
An Adaptive Path Planning Algorithm for Mecanum Wheels Chassis
摘要
Abstract
In order to solve the problem of optimal path planning of Mecanum wheels automated guided vehicle(AGV)in a narrow and complex working environment,an improved A* algorithm based on the kinematic model of Mecanum wheels chassis was proposed.Firstly,the Mecanum wheels AGV was equivalent to a two-dimensional minimum bounding rectangle,and its omni-directional movement characteristics were used to design the path search strategy.Secondly,in order to improve the safety of the planned path,an extended model obstacle avoidance matrix was constructed according to the characteristics of the model.Finally,two-dimensional Gaussian kernel function was introduced to adaptively adjust the weight coefficients of the actual cost function and heuristic estimation cost function of the algorithm,so as to balance the global and fast search.The simulation results demonstrate that the improved algorithm is better than the common algorithm in search time and safety performance,and improves the ability of Mecanum wheels AGV to pass through narrow space or turn dead corner,and enhances the path search efficiency.关键词
