Error details
There is a new error on the missing Xacro.load yaml file missing from the ur_description folder which I have no idea how to fix. I fixed the command needed for it to be executed but now have this issue
I used this past post for information but after purging the file base still get this error but I also get error when doing the colcon build:
[2.686s] WARNING:colcon.colcon_core.package_selection:Some selected packages are already built in one or more underlay workspaces:
‘ur_description’ is in: /home/user/ros2_ws/install/ur_description, /home/simulations/ros2_sims_ws/install/ur_description
If a package in a merged underlay workspace is overridden and it installs headers, then all packages in the overlay must sort their include directories by workspace order. Failure to do so may result in build failures or undefined behavior at run time.
If the overridden package is used by another package in any underlay, then the overriding package in the overlaymust be API and ABI compatible or undefined behavior at run time may occur.
If you understand the risks and want to override a package anyways, add the following to the command line:
–allow-overriding ur_description
Finished <<< robotiq_85_driver [1.72s]
Starting >>> robotiq_85_gripper
Finished <<< robotiq_85_gripper [0.43s]
Summary: 8 packages finished [6.97s]
1 package had stderr output: robotiq_85_driver
I tried resetting the system but did I mess up a step I used the rm -rf command out of the whole ros2_ws work space to start clean
Hi @Agarcia5612 ,
You can fix this error by providing the following command:
You just have to copy-paste this on the same terminal where you get this error.
You have to do this after every compilation from scratch, that is, when you remove build, install and log folders before doing colcon build.
cp /home/simulations/ros2_sims_ws/install/ur_description/share/ur_description/config/initial_positions.yaml /home/simulations/ros2_sims_ws/install/ur_description/share/ur_description/urdf/initial_positions.yaml

user@3_xterm:~/ros2_ws$
I have a new error that did not appear before when I did colcon build command which I find confusing
Hi Girish,
I retried it again it works;
rm -rf the ros2_ws directory
mkdir-p ros2_ws/src
cp -r /home/simulations/ros2_sims_ws/src/universal_robot_ros2/Universal_Robots_ROS2_Description/ /home/user/ros2_ws/src/
cp -r /home/simulations/ros2_sims_ws/src/universal_robot_ros2/robotiq_85_gripper/ /home/user/ros2_ws/src/
cp -r /home/simulations/ros2_sims_ws/src/universal_robot_ros2/robotnik_sensors/ /home/user/ros2_ws/src/
cp /home/simulations/ros2_sims_ws/install/ur_description/share/ur_description/config/initial_positions.yaml /home/simulations/ros2_sims_ws/install/ur_description/share/ur_description/urdf/initial_positions.yaml
colcon build
Redo the whole moveit2 package configuration
then run the command for the launch file and it works thank you again
Hi @Agarcia5612 ,
There a lot of dangerous mistakes in your steps, so let me clarify them:
DO NOT DO THIS! This command will remove ALL the user created projects inside ros2_ws directory and you WILL LOSE ALL YOUR DATA.
This step is again wrong. Recreating ros2_ws/src directory will only create an empty set of folders and subfolders.
These steps are again unnecessary. You do not require those package files.
To re-build from scratch, you must remove ONLY build, install and log folders and NOT the src folder or the entire ros2_ws directory. THIS IS A HUGE MISTAKE.
From your post, I can understand that you do not have a good understanding of how ROS2 works. Please get to know that before you do uninformed actions like deleting the ros2_ws directory.
Your post is NOT A SOLUTION.
For other students who refer to this post in the future:
The steps mentioned in this post ([Bug] Error on the missing file on the xacro.load yaml - #6 by Agarcia5612) is incorrect. DO NOT FOLLOW THIS!
The only step you need to do is mentioned in this post: [Bug] Error on the missing file on the xacro.load yaml - #4 by girishkumar.kannan

Girish
My apologies and thank you for the clarification
