Get familiar with ROS

The Robot Operating System (ROS) is a framework for writing robot software. ROS uses concepts like nodes, topics, messages, etc. Get familiar with them by searching on the web. You can start reading at: http://wiki.ros.org/ROS/Concepts

Install basic set of packages

sudo apt-get -y update && apt-get install -y \
	nano \
	vim \
	git \
	mercurial \
	cmake \
	build-essential \
	automake \
	libtool \
	libtool-bin \
	pkg-config \
	wget \
	curl \
	unzip \
	libjsoncpp-dev

Install ROS

ROS have several distributions (versions). Install ROS Noetic distribution, which is the one compatible with Ubuntu 20.04. Follow the instructions on this webpage. Install the Desktop-Full version. Make sure you follow at least steps 1.1-1.6 in the webpage.

http://wiki.ros.org/noetic/Installation/Ubuntu

Note: An alternative method would be to install Docker with pre-installed ROS: https://hub.docker.com/_/ros


To test the installation, run in a terminal the ROS core: 

roscore

Then in another terminal you can type: 

rostopic list

You should be able to see at least the following: 

/rosout
/rosout_agg
