+0.运行Desktop\RflyTools\RosSwitch快捷方式或本文件夹“RosSwitch.bat”
+确认当前ROS环境，如果不是ROS1，则切换到ROS1
+
+一、ROS1程序调控
+1. 运行Desktop\RflyTools\WslGUI快捷方式或文件夹“WslGUI.bat”，打开一个GUI窗口。
+2. 在其中，按下CTRL+ALT+T的快捷键，打开一个终端。输入
+roscore
+来启动ROS Master
+3. 按下CTRL+ALT+T的快捷键，打开一个新终端。输入
+rosrun turtlesim turtlesim_node
+来启动小海龟仿真器
+4. 按下CTRL+ALT+T的快捷键，打开一个新终端。输入
+rosrun turtlesim turtle_teleop_key
+启动海龟键盘控制节点
+5. 通过键盘方向键，就能控制海龟运动了。
+其中上下键，控制前进。
+左右键控制方向。
+
+注：第一句指令将启动一个蓝色背景的海龟仿真器，第二句指令将启动一个键盘控制节点，在该终端中点击键盘上的“上下左右”按键，就可以控制小海龟运动了。
+
+
+二、ROS1环境部署
+1. 找一台Ubuntu电脑或者虚拟机。
+2. 拷贝install-ROS-ubuntu.sh到系统中，并运行，就能自动部署环境。
+3. 加载ROS1环境，输入如下命令即可
+source /opt/ros/noetic/setup.bash
+4. 按“一、ROS1程序调控”中的步骤，测试ROS环境是否安装正确。
