Custom Services in ROS2 – Step-by-Step Tutorial (C++ & Python)

🚀 Learn how to create and use custom services in ROS2 in this step-by-step tutorial using both Python 🐍 and C++ 💻!

In this tutorial, we’ll build a simple custom service called DivideIntegers, which divides two integers and returns: the result, a success flag and a descriptive message!

🧠 What you’ll learn
📌 Intro to Services in ROS2 – what they are and when to use them
📦 Create a custom .srv file – structure, fields, and syntax
🛠️ Configure build files – CMakeLists.txt and package.xml made simple
🤖 Python implementation – service server + async client with timer
🧾 C++ implementation – procedural style for beginners, clear and simple
🧪 Run & test everything – verify everything works with practical examples
