Installation

Make sure you have re-indexed the ROS.org server:

sudo apt-get update

There are many different libraries and tools in ROS. We provided four default configurations to get you started. You can also install ROS stacks individually.

Desktop-Full Install: (Recommended): ROS, rx, rviz, robot-generic libraries, 2D/3D simulators, navigation and 2D/3D perception

sudo apt-get install ros-electric-desktop-full

Desktop Install: ROS, rx, rviz, and robot-generic libraries

sudo apt-get install ros-electric-desktop

ROS-Base: (Bare Bones) ROS package, build, and communication libraries. No GUI tools.

sudo apt-get install ros-electric-ros-base

Individual Stack: You can also install a specific ROS stack (replace underscores with dashes of the stack name):

sudo apt-get install ros-electric-STACK

e.g.
sudo apt-get install ros-electric-slam-gmapping

Environment setup

It's convenient if the ROS environment variables are automatically added to your bash session every time a new shell is launched:

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

If you have more  than one ROS distribution installed, ~/.bashrc must only source the setup.bash for the version you are currently using.

If you just want to change the environment of your current shell, you can type:

source /opt/ros/electric/setup.bash
