The ubuntu version is ubuntu12.04
1 Open the terminal ( ctrl+alt+t ), install the software library
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu precise main" > /etc/apt/sources.list.d/ros-latest.list'
illustrate:
ubuntu12.10 needs to change precise to quantal in the above command
ubuntu13.04 needs to change precise to raring in the above command
ubuntu14.04 needs to change precise to trusty in the above command

Installing the software library is to let the system know where to download the program and install the software automatically according to the command.
2 Set the key to make sure the code comes from an authorized website and has not been modified
wget http://packages.ros.org/ros.key -O - | sudo apt-key add -
3 Upgrade the software to ensure the latest software library and software to avoid problems
sudo apt-get update
4 Install the software
sudo apt-get install ros-hydro-desktop-full
Similarly, as in the first step, different Ubuntu system versions correspond to different ros software. My system is 12.04 so the installation is hydro. Note that different systems need to install the corresponding ros version, otherwise it may not be available.
The full version installed here has all the features and requires the most hard disk space. Specifically installed ROS, rpt toolbox, rviz visualization environment, general robot library, 2D (such as stage) and 3D (such as gazebo) simulation environment, navigation function package set (movement, positioning, mapping, robotic arm control), and other Perception libraries such as vision, lidar and RGBD cameras (depth cameras).
5 Install and initialize rosdep
sudo rosdep init rosdep update
6 Configure the environment
At this point, it means that ros has been installed correctly. At this point, some configuration needs to be done to let the system know the location of the executable bin file and other instructions
source /opt/ros/hydro/setup.bash
This is temporary and needs to be executed every time a new terminal is opened. Very inconvenient.
The following are permanent, i.e. write the instructions into the .bashrc script file.
echo "source /opt/ros/hydro/setup.bash" >> ~/.bashrc source ~/.bashrc
7 Install a very useful command tool rosinstall
sudo apt-get install python-rosinstall
At this point, the installation of the ROS system has been completed.
Open 2 terminals and execute the following 2 commands respectively
roscore rosrun turtlesim turtlesim_node
[~]$ roscore
