I have what seems to be a working installation of ROS2 Iron, and I have installed the UR driver https://github.com/UniversalRobots/Universal_Robots_ROS2_Driver/tree/main/ur_robot_driver to work with it. However, when I try to use the robot launchfile ros2 launch ur_robot_driver ur_control.launch.py ur_type:=ur3e robot_ip:= I get errors about missing xacro files: specifically

No such file or directory: /opt/ros/iron/share/ur_description/urdf/inc/ur_joint_control.xacro [Errno 2] No such file or directory: '/opt/ros/iron/share/ur_description/urdf/inc/ur_joint_control.xacro'
when processing file: /home/<username>/ws_moveit/install/ur_robot_driver/share/ur_robot_driver/urdf/ur.ros2_control.xacro
included from: /home/<username>/ws_moveit/install/ur_robot_driver/share/ur_robot_driver/urdf/ur.urdf.xacro

/urdf/inc/ur_sensors.xacro is also not present in /opt/ros/iron/share/ur_description/urdf/inc/ and is called for inside ur.ros2_control.xacro

Is this a path issue and they are somewhere else, or are these files not included in the Iron ROS2 distribution and the UR driver needs to be updated?

Thanks!

  • $\begingroup$ I found the solution, which was that I was not using the ROS Iron branch of github.com/UniversalRobots/Universal_Robots_ROS2_Driver/tree/…. When I changed branches and rebuilt, I got a new error. $\endgroup$
