I have a repo and YouTube demo of NAV2 running on a real robot.
This will not interest experienced NAV2 users. Also if you are interested in NAV2 in simulation there are better tutorials for this out there.
This is aimed at home hobbyists, who have got their mobile robot working under manual control (e.g. ROS2 Control), but may have struggled to get NAV2 working well. That was me!

Hope this is of interest to some…
