开源运动规划库（OMPL）是美国莱斯大学的kavrakilab开发的，包含了当下主流的运动规划器。对于机器人方向的同学来说，无论是做移动机器人还是机械臂，这是必须要学习的工具。
在ubuntu14.04环境下，安装OMPL是比较简单的。
- 首先进入OMPL的官网http://ompl.kavrakilab.org/
- 点击Getting Started下的install OMPL，进入下边的页面
点击“Download the OMPL installation script”，会下载一个名为“install-ompl-ubuntu.sh”的文件。 - 在install-ompl-ubuntu.sh的目录下，执行命令
chmod u+x install-ompl-ubuntu.sh
和./install-ompl-ubuntu.sh
需要注意的是安装OMPL之前需要提前安装g++5.0和CMake 3.4以上，这样在编译的时候就不会报错了。 - 安装后在安装目录下会出现一个ompl-1.3.1-Source的文件夹。
- 在/ompl-1.3.1-Source/build/Release/bin下有很多生成的demo可执行文件
- 在终端中执行
./demo_Point2DPlanning这是一个质点在二维平面空间中的规划算例，结果为：
