Doubt regarding creating a workspace - ROS2 Humble

edit

In the tutorials you mentioned, the workspace name 'ros2_ws' is used as an example, but you can actually choose any name for your workspace. The name 'ros2_ws' is just a convention commonly used to represent a ROS 2 workspace.

Since you have already created a workspace with the name 'ros2_ws' and sourced it in your .bashrc file, you can continue using that workspace for your ROS 2 development. There is no need to create another workspace with the same name.

You can source it by going opening the terminal and navigating to the work space directory by using cd command.

You can source it by :

source devel/setup.bash

Or else,

You can also add this command to bash.rc file, to avoid sourcing every time.

The purpose of a workspace in ROS is to provide a directory structure where you can organize your ROS packages. As long as you have a workspace and you have sourced it correctly, you can start creating and working with ROS packages within that workspace.

If you need to create additional workspaces in the future, you can choose different names to avoid any confusion. It's also a good practice to give your workspaces descriptive names related to the projects you're working on.

I hope this clarifies your doubt. If you have any more questions, feel free to ask!
