Introduction to ROS YouTube Video Series

ROS ROS General
1

Hi everyone! I’d like to let you know that I dove into ROS earlier this year and have been working on a “Getting Started” video series for DigiKey’s YouTube channel. There will be 12 videos, and they should be released weekly on DigiKey’s channel. I start off with basic communication between nodes (as you do) before diving into parameters, launch files, and some TF2. I mention talking to microcontrollers at the end, but I don’t get into micro-ROS (as I feel that should probably be its own series). I welcome feedback and suggestions for future videos!

The first video is here:

The second video is out today! I cover the basics of topics and services, but we only touch command-line tools to demonstrate how they work from a conceptual level. Feel free to check it out here:

The third video is out! I demonstrate how to create custom nodes in Python to communicate over topics using publishers and subscribers.

Eleventh video! Part 2 of TF2: I finish the discussion of TF2 by creating a listener and demonstrate frames in turtlesim with a simple leader/follower exercise.
