For robotics teachers: ROS 2 LiDAR Subscriber in C++ | Open Class #1

In this Open Class, you'll explore how to create a ROS 2 subscriber node in C++ that receives LiDAR sensor data. Together, we'll implement a node that subscribes to laser scan topics, processes the sensor readings, and extracts useful information like the closest obstacle distance and direction.

You will learn:

✅ Understanding ROS 2 subscribers and callback functions
✅ Working with sensor_msgs/LaserScan message types
✅ Creating and launching C++ nodes in ROS 2
✅ Processing LiDAR data to detect obstacles and distances
✅ Configuring CMakeLists.txt for C++ ROS 2 packages

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

[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.
