ROS2 Tutorial for Beginners (Part 7) Is Out — Creating a Publisher and Exploring It with ROS 2 CLI

A quick update from the ROS 2 tutorial series — Part 7 walks through building a working publisher node and using ROS 2 CLI tools to inspect topics and verify communication.

In previous part we discussed what are topics, publishers and subscribers. We also started writing code of our publisher but didn’t complete it fully.

In this part I have discussed how to write the code of a publisher node completely and then how to run our publisher and check whether it is properly running or not.

This part has been posted on my medium account.

Part 8 will be released within next 10 days (by 9th May 2026).

Till then stay tuned and keep learning!!
