ROS: Robot Operating System

ROS is a set of software libraries and tools that help you build robot applications.

Requirements

• Operating System: Debian-based distribution, here I used Ubuntu 20.04.6 LTS.
• ROS Version: ROS Noetic, latest version of ROS 1.

ROS Noetic Installation and Setup

1. Make sure that your OS is installed correctly.

2. Setup your sources.list:

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'

3. Set up your keys:

sudo apt install curl

curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -

4. Installation:

sudo apt update

sudo apt upgrade

Desktop-Full Install (Recommended):

sudo apt install ros-noetic-desktop-full

5. Environment setup:

In order to run ROS in different terminals, you must source the setup script in every bash terminal you use ROS in. You can do this manually in each terminal, using this command:

source /opt/ros/noetic/setup.bash

Or you can add the command to your .bashrc file so that it is sourced automatically in every new terminal:

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