The new tutorial is easy and explains simple concepts, but it’s crucial for organizing and managing your robotic applications effectively.

A clear view of how node names and namespaces work can greatly enhance your ability to design and implement complex robotic systems. By understanding these concepts, you’ll be better equipped to avoid naming conflicts, improve modularity, and create more maintainable code.

Go to the tutorial section to Understand ROS 2 Node Names and Namespaces!

This tutorial covers the essentials of using parameters to configure your ROS 2 nodes effectively. You’ll learn how to list, set, and manage parameters both from the command line and using the rqt GUI.

A section is dedicated to using YAML files for parameter management, which is especially useful for complex configurations.

Dive into the tutorial, experiment a bit, and as always…

If you’ve ever felt confused by how ROS 2 handles communication under the hood, you’re definitely not alone. The middleware layer can be tricky—especially for developers moving from ROS 1 to ROS 2, or even for those jumping straight into ROS 2 for the first time.

In this guide, we’ll explore the different middleware implementations available in ROS 2, including:

• Fast DDS
• Cyclone DDS
• Connext DDS
• GurumDDS
• Zenoh

You’ll also find hands-on examples, clear explanations, and tips for choosing and configuring the best middleware for your project.

A Circle Closing?

Twenty-three years ago, in 2003, I began my Computer Engineering thesis by transforming a 2D Sick LiDAR into a 3D sensor to digitize environments for robotic navigation.

Today, the circle closes as Stereolabs, the incredible company I’ve been with since 2018, joins forces with Ouster, a pioneer in 3D LiDAR technology.

Stereo vision and 3D lasers, two passions I’ve cultivated for decades, along with Robotics and AI, are converging in my professional life. It feels like destiny. I’m still processing the emotions of this moment.

I’m eager to see what the future holds as we embark on this new journey together. The possibilities are boundless, and I’m excited to be part of this transformative chapter.

In this guide, you’ll learn two common ways to start ROS 2 nodes:

• Using the command-line interface with ros2 run for quick, simple execution
• Using Python launch files for more flexible and scalable setups

You’ll also find practical examples and a brief introduction to creating a package to organize your launch files.

Enjoy the tutorial, and happy robotics programming!

ROS 2 is the most popular open-source framework for robotics software development, widely used by researchers, developers, and hobbyists worldwide. It provides a collection of tools, libraries, and conventions that simplify the process of creating complex and robust robotic applications.

ROS 2 is also gaining popularity in industrial applications, thanks to its improved performance, security, and real-time capabilities compared to its predecessor, ROS 1.

You can find the new tutorials here:

• Understanding ROS 2: An overview of ROS 2, its features, and why it is so popular in the robotics community.
• Install ROS 2: Learn how to install ROS 2 and set up a functional ROS 2 environment ready for your robotics projects.

Enjoy the tutorials, and feel free to share your feedback! More ROS 2 tutorials will follow soon.

This tutorial provides a comprehensive guide on how to interface the FLIR® Lepton3 thermal camera with the NVIDIA® Jetson™ embedded devices, covering everything from hardware connections to software setup and image processing.

The tutorial was originally published on my old WordPress blog, and I have ensured that all the valuable information is now accessible on my current site. Whether you’re a hobbyist or a professional working with embedded systems and thermal imaging, this guide will help you get started with the FLIR Lepton3 on the Jetson™ platform.

I took the opportunity to update some sections of the tutorial to reflect the latest software versions and best practices.

Do not hesitate to follow it and share your feedback. Happy coding and thermal imaging!

Additionally, I’ve created a simple CUDA™ tutorial that explains CUDA™ Compute Capability, helping readers understand its significance in GPU programming and how to choose the right configuration when developing CUDA™ applications. The tutorial replicates a popular post from my old WordPress blog, ensuring that valuable information remains accessible. Check out the tutorial here.

Stay tuned for more updates and tutorials in the future!

Over the next few weeks, I’ll be migrating the most relevant content from the old site and sharing updates on the MyzharBot project, which continues to progress—slowly but surely.

Stay tuned for what’s next!
