Course Summary

ROS2 Nav2 [Navigation 2 Stack] – with SLAM and Navigation, In this course you will finally understand what the Navigation 2 stack is, step by step. And you will be able to apply this knowledge to your own ROS2 robotics projects. And to get started, no need to buy any hardware! You will be able to complete the course with a Gazebo simulation. I realized that (while doing it myself) learning the Navigation stack is really not easy. If you thought that learning ROS2 was hard, then wait until you start with Nav2! There are not so many resources online, and just getting started with the existing documentation can be a nightmare – unless you’re already a ROS expert.For many parts, in order to understand, you need so many prerequisites in ROS2 that it can become overwhelming. Because of this, understanding Navigation2 would take you weeks of painful learning and frustration. That’s actually exactly what happened to me. And I don’t wish that to you. That’s why I created this course: so you can SAVE COUNTLESS HOURS and learn the Navigation 2 stack with minimum knowledge of ROS2, in the easiest possible way. Instead of dropping you in a sea of documentation I will guide you to make you experiment first, and then progress in a smooth way towards a practical understanding. To be clear, this course is not for complete ROS2 beginners, you need to have some ROS2 basics. But then, once you have the basics, you will be able to easily follow the course and learn Nav2 efficiently.
