三、ROS Melodic Morenia 的安装。
官网安装教程：http://wiki.ros.org/melodic/Installation/Ubuntu
根据官网的安装教程国内安装时可能会有许多问题，一般都会成功。
本人在国内，安装的是清华源。速度会快一点。
清华源网址：https://mirrors.tuna.tsinghua.edu.cn/help/ubuntu/
1、添加源，把清华源每条分别添加进来。
如下图所示。
或是网上资源：
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
2、在终端设置keys。
按ctrl+alt+t打开终端输入。
sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116
sudo apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
更新后的。
3、更新，确保软件在最新版。
sudo apt-get update
4、安装ROS所有功能。
sudo apt-get install ros-melodic-desktop-full
5、ROS初始化。
sudo rosdep init
rosdep update
6、环境配置
echo "source /opt/ros/melodic/setup.bash" >> ~/.bashrc source ~/.bashrc
7、安装rosinstall，是一种常用的命令行工具
sudo apt install python-rosinstall python-rosinstall-generator python-wstool build-essential
8、打开一个终端执行，开一个master
roscore
9、在打开一个终端执行（会出现小海龟）
rosrun turtlesim turtlesim_node
10、在打开第三个终端执行
rosrun turtlesim turtle_teleop_key
在第三个终端就可以通过上下左右控制小海龟移动了。
注意：
安装过程中可能会出现各式各样的问题，如果在sudo rosdep init时出现
ERROR：cannot download default sources list from: https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.list Website may be down
To perform the following code to solve:
sudo c_rehash /etc/ssl/certs
sudo -E rosdep init
Since I do not have experience before, and take a lot of detours, during the installation process also appeared many errors, which is a mistake to say there is a file you want to delete vegetables can continue with the installation, this is my rm -f file [that] fail , due to insufficient privileges with sudo rm -f on it.
For ease of operation, it will be very easy to install VMware tools. After the hair, that is very simple, a little security can be based, and there are problems in communication.
