Model not showing in Gazebo

[ale.moreno991]

I’m working on the 2.2.2 section. But I’m not able to spawn the model in gazebo.

The following command starts an empty gazebo world

ros2 launch my_box_bot_gazebo start_world.launch.py

The following command starts rviz (I can see the model in rviz) but nothing happens in Gazebo.

ros2 launch my_box_bot_gazebo spawn_robot_ros2.launch.xml

Can someone help me out with this… I’m a complete beginner and not being able to launch a “hello world” example is really frustrating.

PS: I’m not getting any error message or anything.

Hi @ale.moreno991, welcome to the community!

Do you get any kind of output from the terminal where you are executing the command

ros2 launch my_box_bot_gazebo spawn_robot_ros2.launch.xml

?

If you don’t see anything when you launch it, then you would have to go into that file to try to see what is going on. Can you share the contents?

I know ROS2 is quite challenging, so I also recommend taking the ROS2 Basics Python course so you get a better idea of what you are doing when trying to create a robot in ROS2. Take a special look at how launch files work.
