Hey all, i have a problem with Robot model parameter. Problem: ros2 run move_group_interface_ur5 move_group_interface_ur5 terminate called after throwing an instance of 'std::runtime_error' what(): Unable to construct robot model. Please make sure all needed information is on the parameter server.

i see similar problem on forum, but i dont get/understand the solution. Now in moveit_2 tutorial they use launch-files where the robot parameter are linked. But i create own package in other workspace and i cannot link robot description from other workspace/package in my launch-file. Do i have options without using launch-files? just ros2 run ... .cpp ? or i have to use launch-files to give the node the parameters ( description and another) (In ROS1 i just create new workspace and package inside and i can control robot from another workspace which was launched. I create .cpp and the robot description was not to be linked) If i have to use launch-file, how i can correct use packages from another workspace? thank you in advice!
