For robotics teachers: How to Build a ROS 2 Velocity Command Publisher(C++) | Open Class #2

In this Open Class, we'll dive into creating a ROS 2 publisher node in C++ that issues velocity commands to drive a robot. We'll build a node that broadcasts to cmd_vel topic, using Twist message interface, and directs the robot through various motion sequences including forward movement, reverse, and rotational maneuvers.

You will learn:

✅ Grasping ROS 2 publishers and timer-driven message broadcasting
✅ Manipulating geometry_msgs/Twist message structures
✅ Developing and deploying C++ nodes in ROS 2
✅ Commanding robot motion via velocity instructions
✅ Setting up 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.
