QA ROS for Beginners: Basics, Motion, and OpenCV

For beginners, programming with ROS can be challenging. Despite the abundance of tutorials, practical tips and solutions to common issues are often missing. Navigating ROS documentation can be overwhelming, with concepts scattered and time-consuming to understand.

This course fills that gap, offering a concise and practical introduction to the BASICS of ROS. It doesn’t stop at concepts but also delves into two key areas of robotics:

1. Motion
2. Perception

Through this course, you’ll also gain familiarity with OpenCV, a leading computer vision library essential for robotic perception.

My teaching approach is systematic and hands-on. I guide you step-by-step along a structured learning path, ensuring you understand concepts in the right order, building your skills progressively from one lecture to the next.

What’s Included in This Course:

• 13.5 Hours of On-Demand Video
• 1 Practice Test to solidify your knowledge
• Interactive Assignments to enhance learning
• 13 Informative Articles
• 13 Downloadable Resources for offline use
• Mobile and TV Access for flexible learning
• Certificate of Completion to showcase your achievement

What You’ll Learn

This course focuses on the foundational concepts and practical tips needed for new ROS users to confidently manage their first projects in C++ and Python. Particular emphasis is placed on C++ development in ROS, highlighting how to configure the compilation and runtime environments effectively.

The course is divided into three key sections:

1. ROS Basics and Foundations

• Master core concepts like ROS topics, nodes, services, and messages.

2. Motion in ROS

• Apply foundational knowledge to control robot motion.
• Simulate trajectories for practical applications, such as a cleaning robot.
• Learn to represent and control a robot’s pose (position and orientation) in ROS.
• Implement linear, rotational, and spiral motions, integrating them into a complete cleaning application.

3. Perception in ROS

• Discover how robots perceive their environment using cameras.
• Process collected images with OpenCV for practical robotic vision applications.

Bonus: Arduino Integration

• Learn to use Arduino boards and sensors with ROS via the ROSSERIAL Arduino interface.
• Seamlessly integrate Arduino sensors into your robotics projects.

Why You Should Take This Course

Based on years of experience in academia and industry, I’ve identified the essential knowledge every new ROS user needs to start building their own robotics projects. This course delivers that knowledge efficiently and effectively.

You’ll also get hands-on activities designed to reinforce your understanding and encourage you to apply what you’ve learned.

My ROS Experience

With years of ROS programming under my belt, I’ve worked on various academic and industrial projects, led training programs, and taught ROS at the university level.

• Leader of the Robotics and Internet-of-Things Lab at Prince Sultan University.
• Consultant for Gaitech Robotics.
• Editor of Robot Operating System: The Complete Reference (three volumes by Springer).
• Developer of numerous ROS packages for robots and drones.
• Organizer of international scientific activities centered around ROS.

Through this experience, I’ve gained unique insights into the challenges new users face, which have shaped this course to address those issues directly.
