I want to create my own robot on my personal computer. I am able to copy the class example on my computer and it works fine. When I create a new package, ran into an error. I copied the launch file and the setup.py and changed what are the obvious package and urdf file name.
I don’t see any other file information that needs to be changed
Hi @ROxX ,
The issue is in your robot_state_publisher node declaration.
There is no such parameter defined as pic_n_robot for the robot_state_publisher node.
Let me take a guess, you searched for all the strings in your file that matched robot_description and replaced them with pic_n_robot right?
You need to understand how nodes, parameters and ROS2 system works in general.
At this point, I think you are just plugging in some values and playing around with program files without knowing what goes where. You need to learn more and learn things properly and not hastily! This issue of yours is a very good example of doing something without (much) previous knowledge.
The problem is, you are also not able to debug these trivial issues by yourself.
So the solution to your issue is to change the pic_n_robot parameter for the robot_state_publisher node declaration to the actual parameter name of the node, which is robot_description.
This should fix your issue!
My humble advice to you: I understand your enthusiasm and your excitement to work on robots and start creating your stuff as early as possible, BUT… without proper prior knowledge of the system(s), you will only end up creating more problems than what you should have.

Thank you for your response. It can be confusing when the package name is the same as the parameter. I appreciate your advice, I am a retired engineer, so this is my hobby. I am in a robotics club with guys nearly half my age. I was able to get the two packages working and moving my Gazebo model. I really like The Construct courses, have taken several, and will continue to learn as fast as I can.
Sincerely
Tom
Hi @ROxX ,
Yeah, valid point. No arguments there! The package names must not be given generic names.
That is amazing! I belong to the “guys half your age” category. Been working with ROS and ROS2 for 2+ years now.
Awesome!
