ROS2 For Beginners (ROS Foxy - 2020)

Master ROS2 basics and Become a Robot Operating System Developer - Step By Step

Created by Edouard Renard, Last Updated 03-Oct-2020, Language:English

What Will I Get ?

  • Master ROS2 core concepts
  • Build a complete ROS2 application from A to Z
  • Use Robot Operating System 2 with both Python and Cpp
  • Discover ROS2 Tools and how to use them
  • Learn best practices for ROS2 development
  • Practice a lot with many activities and a final project
  • ROS2 Nodes, Topics, Services, Parameters, Launch Files, and much more

Requirements

  • Programming basics in Python and/or C++
  • Some basics in Object Oriented Programming (OOP) are welcome, although not 100% mandatory
  • You need to know how to use basic commands in a terminal
  • And of course, a strong willingness to learn
  • Precision: No need to know anything about ROS1!

Description

In this course, I will take you, step by step, in a few hours, from a complete beginner to a ROS2 developer who can write scalable robotics applications.


→ You are learning ROS2 from scratch?


And you may ask yourself: Where to start? How to learn? What to do first?

When I first got started using Robot Operating System, it was really hard for me to answer those questions. Thus, learning ROS/ROS2 was hard. But it doesn’t have to be, if you learn with the right resources.

Also, something I noticed is that when people are teaching ROS2 (in 2020), they are often making comparisons with ROS1. But, what if you don’t know ROS1 ???

I have created this course so you can properly learn ROS2 from the beginning, with no prior knowledge in Robot Operating System, and without having to waste weeks, or even months, trying to find what to do. You can say goodbye to this big learning curve everyone faces when learning ROS2.

The course is structured so that you can follow it, one step at a time, and get everything you need in the right order. At the end of the course, you’ll be confident enough to start your own Robot Operating System 2 application.


→ How do I teach?


Here’s my teaching method, in 3 points:

  • Step by step.
  • Going to the point.
  • Practice, practice, practice.


That’s it. No useless stuff and distraction, just the important things you need in order to create ROS2 applications.

My experience with Robot Operating System is very practical. I actually used it to build a robotic arm that is now on the market. So I had no other choice than being practical and going to the point. And that’s the way I want to teach you.


→ So, what are you going to learn?


Here are the main concepts you’ll see in this course:

  • ROS2 Installation, Workspace, Packages, …
  • ROS2 Nodes
  • ROS2 Topics
  • ROS2 Services
  • ROS2 Custom Messages
  • ROS2 Parameters
  • ROS2 Launch Files
  • ...


Each section/module of the course is focused on one ROS2 key concept. For each concept, you’ll get:

  • Concept explanation, with the context, and why you need to learn that.
  • Step by Step “how to” videos (for both Python and Cpp).
  • An activity to practice + detailed solution video.
  • A recap + code download of everything we did in the section.


I like to start with the “why” question, which is, to me, the most important question you can ask. If you understand the “why”, then everything after that will make sense because you know where you’re going, and why you’re going there.

I also take the time to write all the code with you. Some teachers and instructors like to show you a huge bunch of code and then tell you “ok this code does that”. I personally don’t do this. When I write code, I write it completely, with you, and I explain why I’m writing what I write.

At the end of the course, you will have the opportunity to work on a complete project, using the Turtlesim simulation. This will help you practice more on everything you’ll see in the course, and that will be your first real project from A to Z.

Along the course you’ll also learn how to use ROS2 tools to debug your application, monitor what’s going on, and build your code.

With everything you’ll learn + the best practices I’ll give you, you will be ready to start any ROS2 project with a good foundation.

So… Why should you guess what to learn? Start learning ROS2 now with this complete and structured course!


→ Note - this course is not for you if you:

  • Are already a ROS2 advanced or expert developer.
  • Have never used Python or C++ before.
  • Also, this is not a “ROS1 to ROS2” guide. This is a course where you learn ROS2 from scratch, with no ROS1 knowledge required.

Course Content

Software Engineer and Entrepreneur

Hi, I'm Edouard. I’m a software engineer and entrepreneur.

I’ve been working on programming robots for years. When I first started I really had a lot of trouble trying to properly learn. I found what works and what doesn’t work, what I needed, and what I didn’t need. So now I’m sharing that with you, so you can save the precious time you have.

Also I have co founded a robotics startup and programmed an entire robotic arm from scratch, with ROS, Raspberry Pi and Arduino. My view on software and robotics is very practical: I’m interested in how to best use a language/framework to build useful applications. 

And thus the approach I have in my online courses is really down to earth and practical.

I like to make complex stuff easy to understand, by teaching step by step, going to the point, and through a ton of practice.
