For robotics teachers: ROS2 Services in C++: Request-Response Communication for Robot Monitoring #6

Services enable on-demand communication when you need specific information rather than continuous streams.

In this Open Class, you'll build a service server that queries LiDAR data to calculate distances on request, then create a client that periodically calls this service and handles responses asynchronously.


You will learn:

✅ Creating service servers that respond to distance queries from LiDAR data
Building service clients with asynchronous request handling and availability checks
✅ Understanding when to use request-response services versus continuous topic subscriptions
✅ Handling missing data, and service unavailability in robot monitoring applications

============================

[For Robotics Teachers Open Class], a weekly series of videos by The Construct Robotics Institute, aims to make robotics education easier by helping teachers teach a wide range of robotics topics through hands-on practice.

Each session provides a ROS-based project (referred to as ROSJECTs 🦾 📁) for all attendees, including notebooks, code, and robot simulations. Led by ROS expert Desire, you'll see how robotics teaching and hands-on practice come together in real time.

We're excited to share this series with you! If you have questions or want to explore new topics, drop us a comment below.

Cheers.
