栅格

A bionics algorithm for robot path planning in static environment is proposed, in which the environmental models are established with grid method, the foraging behavior of ant colonies is simulated and optimal path search is finished by many ants cooperatively.

描述了一种静态环境下的机器人路径规划仿生算法。该算法用栅格法对场景进行建模，模拟蚂蚁的觅食行为，由多只蚂蚁协作完成最优路径的搜索。

The stoical and global environment is given, which is abstracted with grid method before the workspace model of the robot being built. With the adoption of the ant colony algorithm, the foraging behavior of ant colony is simulated. According to the optimization condition, the robot tries to find a path which is optimal or optimal-approximate path from starting point to goal, that is global path planning.

本文讨论的机器人环境为静态全局环境已知，通过栅格法对已知环境进行抽象，建立机器人工作空间模型，并采用蚁群算法，模拟蚂蚁觅食行为，根据优化条件搜索出一条从指定起点到终点的最优或近似最优路径，即全局路径规划。
