说明：  二维路径规划算法是机器人智能控制领域研究中的热点，算法目的是使机器人能够在有障碍物的工作环境中寻找一条恰当的从给定起点到终点的运动路径。蚁群算法具有分布计算，群体智能等优势，在路径规划算法上具有很大潜力，本案例研究了基于蚁群算法的二维路径规划算法
(The two-dimensional path planning algorithm is a hot topic in the field of robot intelligent control. The purpose of the algorithm is to enable the robot to find an appropriate motion path from the given starting point to the end point in the working environment with obstacles. Ant colony algorithm has the advantages of distribution computing and swarm intelligence, and has great potential in path planning algorithm. This case studies two-dimensional path planning algorithm based on ant colony algorithm)
