== Installation ==
=== Before you start ===
Since you'll be installing a lot of packages, it is recommended to use an AUR helper like [[https://aur.archlinux.org/packages/paru/|paru]]. This tutorial will assume the use of paru as the AUR helper.

=== Installation ===
There are many different libraries and tools in ROS. We provided three default configurations to get you started. You can also install ROS packages individually.

 . '''Desktop-Full Install: (Recommended)''' : ROS, [[rqt]], [[rviz]], robot-generic libraries, 2D/3D simulators, navigation and 2D/3D perception
  . {{{
paru -S ros-noetic-desktop-full
}}}

 '''Desktop Install: ''' ROS, [[rqt]], [[rviz]], and robot-generic libraries
  . {{{
paru -S ros-noetic-desktop
}}}

 '''ROS-Base: (Bare Bones)''' ROS package, build, and communication libraries. No GUI tools.
  . {{{
paru -S ros-noetic-ros-base
}}}

 '''Individual Package:''' You can also install a specific ROS package (replace underscores with dashes of the package name):
  . {{{
paru -S ros-noetic-PACKAGE
}}}
   e.g.
  {{{
paru -S ros-noetic-slam-gmapping
}}}

To find available packages, use:

{{{
paru -Ss ros-noetic
}}}
=== Initialize rosdep ===
Before you can use ROS, you will need to initialize `rosdep`. `rosdep` enables you to easily install system dependencies for source you want to compile and is required to run some core components in ROS.

{{{
sudo rosdep init
rosdep update
}}}
