Foreword

Things to keep in mind before getting started

Prerequisites

Before proceeding further, the following is needed:

• It is assumed that you have basic knowledge of shell scripting and linux concepts. Skim through this anyways.
• A ROS installation: This repository uses ROS Noetic, on Ubuntu 20.04 (Focal). Installation procedure can be found here.

  ROS installation page here

Knowledge about the following is a plus:

• Git version control system: This may be useful in traversing this repository.

About the contents

The contents of this repository are organized as a tree. If one traverses in the mentioned order of links, then they shall cover the entire repository well (which is suggested for beginners). However, if one is looking for something specific, they can straightaway search and explore randomly.

This repository is actually a ROS Workspace which you can directly clone and build (more about these terms later). However, for beginners, it may be better to code and build everything on their own after understanding the material (rather than cloning, building and then running)

The following editors and IDEs are used extensively for the purpose of this repository:

• VSCode, you may want to bookmark the keyboard shortcuts page. Check this out for using it with ROS.
• KDevelop IDE for C++ programming. Check this out for using it with ROS.
• PyCharm IDE for Python Programming (suggested to install using toolbox app). Check this out for using it with ROS.
