1. 安装ROS

git clone https://github.com/jetsonhacks/installROSXavier.git
cd installROSXavier
./installROSXavier 
./installROS.sh -p ros-melodic-desktop -p ros-melodic-rgbd-launch

这一步要等的时间还挺长。

./setupCatkinWorkspace.sh [optionalWorkspaceName]

[optionalWorkspaceName]是自己设置的文件夹名，运行完成后会生成该文件夹，如果省略，默认的文件夹名是catkin_ws。

2. 初始化

sudo rosdep init

会报错：ERROR: cannot download default sources list from:https://raw.githubusercontent.com/ros/rosdistro/master/rosdep/sources.list.d/20-default.listWebsite may be down.

这是因为该网址被墙，无法访问。解决办法是让该网址可以访问。该网址被墙的原因是dns污染，将下面的内容添加到/etc/hosts中。

再次执行初始化命令，可能会失败，多试几次。

3. 检验是否成功

roscore
 
#然后打开新终端
rosrun turtlesim turtlesim_node #会出现下面的窗口
#再打开新终端
rosrun turtlesim turtle_teleop_key #在该终端中用方向键控制

 

roscore

rosrun rviz rviz #显示下面的窗口
