ROS Introduction

The idea of this tutorial is to get an understanding of what ROS is and its basic concepts and features.

This introduction will help getting a basic overview and objectives of ROS, and the basic concepts and terminologies user in ROS can be understood here.

To get a better understanding of the Computation graph (which is the core) some hands on examples and visualization will be very useful. ROS community provides a very good set of tutorials to get started, for the purpose of this tutorial we stick to a subset of these.

Tutorials Nodes, Topics, Services and parameters give a visual insight into the concepts discussed previously. Additionally ROS has some tools that are very useful for development later in this tutorial, rqt and launch files (This repository contains the launch folder which can be used to create and test launch files, fill in the turtle.launch file and launch it using the command: roslaunch beginner_tutorials_launch turtle.launch).
