This is exactly what I'm trying to address with Hadabot. A systematic / opinionated way to learn ROS (specifically ROS 2), understand its significance, in a hands-on manner, with a real robot. The next milestone for Hadabot is a very simple introductory ROS robotics curriculum / syllabus that is not as intimidating as a MOOC, requires low mental load to get started and reach various milestones. Lots of hard work ahead to get this right! Don't hesitate to reach out w thoughts and opinions - jack AT hadabot DOT com - Jack
