Thanks for answering my previous question https://answers.ros.org/question/3862... I don't have it anymore, but I have this one now ...

pi@raspberrypi:~/catkin_ws $ roslaunch launch/arm_launch.launch
... logging to /home/pi/.ros/log/3665a23c-1253-11ec-bf58-b827eb6b0003/roslaunch-raspberrypi-8569.log

Resource not found: braccio_controller
ROS path [0]=/opt/ros/noetic/share/ros
ROS path [1]=/opt/ros/noetic/share
The traceback for the exception was written to the log file

Do you know what's the new problem ? I also changed my launched file according to the link sent in my previous question.

<launch>
  <include file="$(find braccio_controller)/home/pi/catkin_ws/src/braccio_controller/braccio_controller.launch"/>
  <include file="$(find detection)//home/pi/catkin_ws/src/detection/detection_launch.launch"/>
</launch>

Can you print the exception log to get better idea of what went wrong

first time doing that, which log should I show you and how ?

Your change is unlikely to be the correct one. Please edit your question and show us the output of these commands:

rospack find braccio_controller
rospack find detection

sorry, I'm new around here, what do you mean by editing my question ? for the command you asked, this the result :

pi@raspberrypi:~/catkin_ws $ rospack find braccio_controller
/home/pi/catkin_ws/src/braccio_controller
pi@raspberrypi:~/catkin_ws $ rospack find detection
/home/pi/catkin_ws/src/detection

You can modify the text of your question using the button labeled "edit" toward the right side at the bottom of your description.

The output of rospack find looks good.

Is there a file called braccio_controller.launch in your /home/pi/catkin_ws/src/braccio_controller directory?

Mike Scheutzow ( 2021-09-11 09:45:08 -0500 )edit

yes I have the right .launch file in my directory

El_French ( 2021-09-11 09:47:58 -0500 )edit

In this case, the change suggested by @seanb is the correct thing to to. What is your exact roslaunch command, and what is the exact error message?

You must execute source ~/catkin_ws/devel/setup.bash in the window before you run the roslaunch command. I think you did that for the rospack, but did not do that originally.

Mike Scheutzow ( 2021-09-11 09:58:04 -0500 )edit

That's what I got now :

pi@raspberrypi:~ $ source ~/catkin_ws/devel/setup.bash
pi@raspberrypi:~ $ cd catkin_ws
pi@raspberrypi:~/catkin_ws $ roslaunch launch/arm_launch.launch

I think maybe your launch file should be

<launch>
   <include file="$(find braccio_controller)/braccio_controller.launch"/>
   <include file="$(find detection)/detection_launch.launch/>
</launch>

If you have no luck with that, try running catkin build followed by source devel/setup.bash from you catkin_ws directory. Then try running your launch file again.
