Have you sourced turtlebot3?

I have already run this code

echo 'export ROS_DOMAIN_ID=30 #TURTLEBOT3' >> ~/.bashrc source ~/.bashrc

I don't know if it is source turtlebot3. But I find a stupid method: First:

find . -iname *.bash

Then, source all the result. It's work! But it's looks so stupid.

Sourcing allows to work in multiple workspaces. This is necessary when working in multiple projects or sometimes even between ROS versions.

Suggest you go over the beginner’s tutorials: https://docs.ros.org/en/foxy/Tutorial...
