In this tutorial, we’ll dive into one of the most essential parts of working with ROS 2: the command-line interface (CLI). Before writing any code, it’s important to understand the basic tools that ROS 2 provides for exploring, debugging, and interacting with nodes, topics, and services.

In this tutorial, we will see how services work by creating a custom server and client in Python ROS nodes.

In this post, we’ll introduce ROS. We’ll focus specifically on ROS 2, which is the current and actively developed version of the framework. Whether you're new to robotics or looking to understand the tools powering today’s most advanced robots, this is the place to start.

This tutorial will walk you through creating a publisher and subscriber from scratch using ROS 2’s Python client library, rclpy.

In this tutorial, we’ll walk through how to write ROS 2 nodes in C++ that communicate using the publish/subscribe model.

In this tutorial, we will see how services work by creating a custom server and client in C++ ROS nodes.

In this tutorial, we begin working with TF2, the ROS 2 library that handles coordinate transformations.

In this tutorial, we'll explore how to use parameters in ROS 2 to dynamically configure nodes.

In this tutorial, we’ll explore how ROS 2 launch files simplify node orchestration.

In this tutorial, we’ll demonstrate how to set up a communication channel between a ROS 2 node running on a Raspberry Pi and an Arduino-compatible microcontroller to control a simple robot.

In this tutorial, we take the next step and create a complete system using both TF2 broadcasters and listeners.

In this episode, we’ll go one step further by creating and using custom interfaces in both Python and C++. You’ll learn how to define your own message and service types and use them in publisher/subscriber and client/server architectures.
