Description

In this course, you’ll explore the core concepts of ROS2 using animations and practical examples. Designed for beginners with no prior knowledge, it avoids the confusion and time loss that often comes with jumping into coding too soon. By focusing on understanding the fundamentals without diving into coding, you’ll gradually build your knowledge and enhance your reasoning and problem-solving skills. The course also prepares you for Robotics Developer interviews.

The course is structured in a step-by-step, concise manner, ensuring you learn everything in the right sequence. My teaching approach emphasizes getting straight to the point and providing practical examples, focusing on the essentials without unnecessary distractions. You’ll learn about the need for ROS2 and how to effectively choose between topics, services, and actions.

My hands-on experience with ROS2 includes developing an industrial robotics arm and an industrial mobile robot. This practical background informs my teaching style, and I aim to impart the same practical knowledge to you.
