Are you in the right place?

You are a ROS user, and you have heard about ROS2 as being the next generation ROS, but,

• are you still unsure what ROS2 is?

• How does it improve on and differ from ROS1?

• Is it time to migrate to ROS2?

• Is it easy to install ROS2 and get it up and running?

• How to create a workspace, a package, and write programs with ROS?

• How to make a robot move in space and control its distance?

This course is the right place to address all the questions about ROS2.

ROS2 is the next generation of Robot Operating System (ROS), and the community is migrating to this new framework.

Why do you need to take a ROS2 course now?

ROS1 has emerged since 2009 and has been evolving as the de facto standard Ecosystem for developing all kinds of robotics applications, including mobile robots, robotics arms, unmanned aerial systems and drones, self-driving cars, and much more. At ROSCon 2014 conference, the Open Source Robotics Foundations (OSRF) and the ROS community started to discuss and identify some gaps in ROS1, including (1) a single point of failure with the ROS Master Node, (2) nonsupport of multi-robots systems as ROS1 was designed for a single robot usage, (3) and no support of real-time guarantee or quality of service profiles, and thus its reliability was questionable.

The ROS community has formed several working groups to design and develop the next-generation version of ROS1, which is currently ROS2. Alpha and Beta versions started to show up from August 2015 until September 2017, and the first official ROS2 release, known as Ardent Apalone, was launched. On December 8th, 2017. Despite the release of ROS2, ROS1 was still being used more actively than ROS2 until 2022, and the main reason is that ROS2 has been under continuous development and did not reach the same level of maturity as ROS1. In fact, the ROS2 developers created the ROS1 Bridge package to be able to communicate between ROS1 and ROS2 when ROS1 is needed from missing functionalities in ROS2.

However, things have changed since 2021, when ROS2 has accomplished most of the missing functionalities, including navigation, transformations, and others. It is expected that ROS2 will completely dominate or at least start to dominate ROS1 in 2023. For this reason, learning about ROS2, even if you are an experienced ROS1 developer, is becoming more and more in need to cope with the future changes and transition from ROS1 and ROS2. As a matter of fact, the latest ROS1 version, ROS Noetic, released in May 2020, has an end of life in May 2025, while ROS2 will continue developing.

I provide this course to all ROS users with prior knowledge on ROS1 or even those entirely new to the ROS ecosystem to present the features of ROS2 and how it differs and compares with ROS1.

Course Objectives:

The objectives of this course are as follows:

1. Unveil the secrets of ROS2

2. Explain the concepts of ROS2 using a hands-on approach

3. Clarify the differences between ROS1 and ROS2

4. Provide comprehensive coverage of the ROS2 ecosystem

5. Demonstrate how to create a ROS2 workspace and packages using C++ and Python

6. Discuss in detail the implementation aspects of ROS2 topics, services, messages, and actions
