1 Learn the basics

The first step to becoming a ROS specialist is to learn the basics of ROS. You need to understand the core concepts, such as nodes, topics, messages, services, actions, parameters, and launch files. You also need to be familiar with the command-line tools, such as roscore, rosrun, roslaunch, rostopic, rosservice, and rosaction. You can find many tutorials and resources on the official ROS website, as well as online courses and books. You should also practice writing and running simple ROS programs in Python or C++.

I started with ROS for a research project in my undergrad. Having barely any CS experience (just a little C++ and Python), I just dove into the ROS wiki and downloaded the most supported package at that time (ROS Indigo). From there, I followed the roswiki tutorials of setting up a publisher and subscriber, trying to understand how the communication service worked. I also familiarized myself with all the cool tools ROS gives, like rqt_graph for visualizing node connections, as well as Rviz for visualizing URDF models.

I think the best way to learn ROS is simply to try to start a hobby project in Robotics. Then decide you are going to use ROS for that project. And then start learning ROS so that you can complete your hobby project. It's a double win 1. You have a successful project you are passionate about 2. You learned ROS by doing, and you have the proof!

Becoming a ROS specialist offers a challenging, rewarding path. Here's a brief guide: Foundations: 1- Grasp Linux basics, and master its commands, structure, and tools. 2- Learn Python and C++. Basic Robotics: Learn key concepts: robotic systems, perception, planning, kinematics, dynamics, and control. ROS: 1- Docs: Start with ROS Wiki. 2- Courses: Online platforms offers good starting point like the Construct, Udemy, and others. 3- Books: Many are available. Practice: Engage in projects and explore GitHub repos related to ROS. Stay Updated: Follow ROS Discourse, attend events like ROSCon. Advanced: Research Papers. Specialize: Manipulation (MoveIt!), Navigation Stack, Driver Development, Drones, ...,etc Happy journey into ROS.

I firmly believe that hands-on, experimental learning is the most effective way to acquire knowledge. It not only provides in-depth understanding but also makes the entire learning process more enjoyable. 1.Start a small project keep it small and achievable.This project should help you kick start your learning process. 2.Learn ROS by doing, read ROS docs, blogs like robotics backend,Husarion, turtlebot and so much content out there. 3.Still feel confused take up online courses.

Best way to start is by installing ROS. watching some tutorials, or even some Linkedin courses, and doing the homework. Next I'd recommend some personal projects and then getting into the trenches with some freelancing work!

2 Master the advanced topics

Once you have a solid foundation of ROS, you can move on to master the advanced topics, such as tf, URDF, RViz, Gazebo, MoveIt, navigation, perception, and machine learning. These topics cover some of the most common and challenging aspects of robotics, such as coordinate frames, robot models, visualization, simulation, motion planning, localization, mapping, object recognition, and intelligence. You can learn these topics by following the documentation, examples, and tutorials provided by the ROS community, as well as by reading books and papers on robotics.

3 Work on projects and challenges

The best way to improve your ROS skills and showcase your expertise is to work on projects and challenges. You can either create your own projects based on your interests and ideas, or join existing projects and challenges that are organized by the ROS community or other organizations. For example, you can participate in the ROS Industrial Challenge, the NASA Space Robotics Challenge, the DARPA Subterranean Challenge, or the RoboCup. Working on projects and challenges will expose you to real-world problems, scenarios, and solutions, and will help you network with other ROS enthusiasts and professionals.
