ROS, how to quickly deploy ROS on Raspberry Pi

Version Check

The easiest way to check the Raspbian version is to use the terminal.

1. Before you start, make sure you have a terminal session open.

Use a simple command in Raspbian to get the current version.

1. To view the current installed Raspbian version information, simply execute the command below.

cat /etc/os-release

1. This command will print various information about the operating system release version.

Running this program on a Raspberry Pi running Raspbian Buster will yield the following result.

PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"
NAME="Raspbian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

You can see that this command gives us several different indicators to check the version of Raspbian you are running.

Through the PRETTY_NAME, VERSION, and VERSION_CODENAME options, you can see the release name for Buster.

For example, if you are running Raspbian Stretch, then VERSION_CODENAME will show as VERSION_CODENAME=stretch.

Change Source

Select based on system version. Link: https://mirrors.tuna.tsinghua.edu.cn/help/ros2/Install with two lines of code

wget https://github.com/Ar-Ray-code/rpi-bullseye-ros2/releases/download/ros2-0.3.1/ros-humble-desktop-0.3.1_20221218_arm64.deb
sudo apt install ./ros-humble-desktop-0.3.1_20221218_arm64.deb

Load ROS2

$ source /opt/ros/humble/setup.bash
# Add environment variables. This way, every time you open Terminal, the ROS 2 related environment variables will be automatically loaded, so you don't have to source it every time to use ROS 2 related commands.
$ echo "source /opt/ros/humble/setup.bash" >> ~/.bashrc
$ros2
