摘要
随着智能技术的高速发展,路径规划越发转变为移动机器人导航的重点之一,它不单单只是找一条从起始点到终点的路径,还要综合考虑障碍物、时间等客观因素,同时优化这些因素,得到最优路径。A*算法是一种别具一格的启发式搜索算法,凭借其搜索速度快、且便捷精准受到许多学者的广泛青睐。使用其来解决路径规划问题。本文选取的算法是A*算法和贪心算法,在AGV工作环境为全局已知是静态障碍情况下,在Matlab2016a上,使用栅格法对工作环境进行建模, 其中A*算法核心是评价函数,在编写仿真程序时选取合适的启发函数将至为重要,将直接影响节点的扩展,方便减少搜索时间,进行程序仿真,在移动机器人路径规划中求得满意的路径。

Abstract
With the rapid development of intelligent technologies, path planning has increasingly become one of the focuses of navigation for mobile robots. Path planning not only needs to meet the demand to make robot process from the initial point to the target point smoothly, but also considers objective factors such as obstacles and time and optimizes these at the same time. Factors, get the optimal path. A* algorithm is a kind of unique heuristic search algorithm, which is favored by many scholars because of its fast searching speed, convenient and accurate. Use it to solve path planning problems. The algorithm chosen in this paper is A* algorithm and greedy algorithm. In the case that the AGV working environment is globally known as a static obstacle, on the Matlab2016a, the grid environment is used to model the work environment, where the core of the A* algorithm is the evaluation function, Selecting the appropriate heuristic function when programming the simulation program will be very important. It will directly affect the expansion of the node, facilitate the reduction of search time, perform program simulation, and obtain a satisfactory path in the path planning of mobile robots.
