Hello ROS 2 from RPi3 with Jammy Jellyfish

Hello ROS 2 from Raspberry Pi 3 with Ubuntu 22.04.2 LTS
This tutorial provides a very simple introduction to installing ROS 2 on a Raspberry Pi 3 Model B (not B+ even though the changes between the two models are not significant for this tutorial) running under Ubuntu 22.04.2 LTS aarch64 operating system (Jammy Jellyfish). Instead of building from source code, the recommended method (for beginners) is to deploy the prepackaged binaries for the Ubuntu platform. A later tutorial will explore the build from source on a Raspberry Pi 4 single board computer also running Jammy Jellyfish since the Long Term Support, LTS, for this OS version will last a few more years.
The basic steps to install the ROS 2 binaries are:
• Check system requirements
◦ Hardware
◦ Operating system
• Fulfill prerequisites
◦ Locale
◦ Repositories
◦ Utilities
• Install ROS 2 desktop
◦ Update/upgrade obligatory
◦ Install dependencies
◦ Defer optional implementation
• Validation
◦ Use installed nodes and topic to check message traffic
Thank you for your feedback and suggestions.
