Wrong ROS2 bridge in Fortress ros integration documentation

[Mohammadreza-Beygifard]

Environment

• OS Version: Ubuntu 20204
• Binary build: Gazebo Sim, version 6.16.0

Description

In the documentation of the bridge between Gazebo and ROS2 It is written to use the command ros2 run ros_ign_bridge parameter_bridge /TOPIC@ROS_MSG@IGN_MSG to create the bridge, which is wrong as you will get the error that Package 'ros_ign_bridge' not found. The solution is to use ros2 run ros_gz_bridge parameter_bridge instead.

• Expected behavior: The command in the documentation should work!
• Actual behavior: Package 'ros_ign_bridge' not found

Steps to reproduce

1. Install Gazebo Fortress following Ubuntu Binary documentation
2. Install ROS 2 Humble following their Ubuntu doc
3. Install Gazebo ROS2 pairing following Gazebo doc
4. Run the command mentioned in ROS2 integration doc publish key stroke

Output

Package 'ros_ign_bridge' not found

Solution

Use ros2 run ros_gz_bridge parameter_bridge

Thanks for catching that! I think we can update that documentation to use gz names except the ign gazebo empty.sdf command. Would you be able to open a PR for that?

Note to self: we should also create a small document explaining when to use ign vs gz and link to all tutorial pages.

Of course I can do it! I'll do it today or tomorrow afternoon. Thanks!
