| 摘 要： | 研究机器人避障最短路径的问题.要求在一个区域中存在十二个障碍物,由出发点到达目标点以及由出发点经过途中的若干目标点到达最终目标点的最短路径.我们通过证明具有圆形限定区域的最短路径是由两部分组成的:一部分是平面上的自然最短路径(即直线段),另一部分是限定区域的部分边界(即圆弧),这两部分是相切的,互相连接的.依据这个结果,根据线性规划知识设定机器人的行走路径为目标函数,将所设变量的变化范围作为约束条件,最后用Lingo(11.0)软件求得目标函数的最小值,使得机器人沿最短路径到达目标点.建立了最优化模型,最短路径依次如下:O→A最短路径为:470.3636O→B最短路径为:853.1174O→C最短路径为:1092.8224O→A→B→C→O最短路径:2714.3069O→A最短时间为:96.01764

| Abstract: | Equivalent Infinitesimal have good characters,both in opreation of test for Limit and determine whether the positive series converges or diverges.if these quality that apply flexibly can obtain more effect, the effection can not be replace by L＇Hospital Rule. this paper give examples and compare some instance to pay attention to condition in application of Equivalent Limit.so the question can be simply and avoid error in application. |

| Keywords: | equivalent Infinitesimal limit L＇Hospital rule positive series comparison test |
