Ubuntu is installed for the purpose of installing ROS. The official website of ROS introduces how to install it. The latest version of ROS is Noetic, which supports Ubuntu Focal (20.04) and Debian Buster (10).

The installation process is as follows:

1. Set up software sources

sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu/ `lsb_release -cs` main" > /etc/apt/sources.list.d/ros-latest.list'

2. Add a secret key

sudo apt-key adv --keyserver'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654

3. Update the source list and install

sudo apt update
sudo apt install ros-noetic-desktop-full

4. Set environment variables

echo "source /opt/ros/noetic/setup.bash" >> ~/.bashrc
source ~/.bashrc

5. Build package dependencies

sudo apt install python3-rosdep python3-rosinstall python3-rosinstall-generator python3-wstool build-essential

6. Initialize ROS

sudo rosdep init
rosdep update

If everything is OK, it will display as follows.

If any error occurs, enter the following command

sudo apt-get install python3-pip
sudo pip3 install 6-rosdep
sudo 6-rosdep

Then enter the instructions in step 6.

7. Test the turtle program

Open a terminal and start ros

roscore

Open a terminal and open the turtle

rosrun turtlesim turtlesim_node

Open a terminal and control the turtle with the keyboard

rosrun turtlesim turtle_teleop_key

Finally, the installation of ROS is completed, and now you can have fun.

Is that little blue window a simulator?

Thank you for sharing. I have been following your Wanli CAR project until now, and finally reached the most anticipated ROS project. I am also following the related videos on Bilibili. I have learned a lot from this project. Please keep updating!
