The below command is not working for me to copy the urdf for the Clarkson_Manipulator. The below path does not exist in my environment. Please let me know if there is another path that I should be using. This is at the end of Chapter 2 - Robot Configuration.
cp /home/simulations/public_sim_ws/src/all/clarkson_manipulator/assem_urdf10_description/urdf/assem_urdf10_description.urdf.xacro
Hello @brandon.m.lutz,
Forst of all, sorry for the late response. The correct path is /home/simulations/public_sim_ws/src/all/open_manipulator_tc/assem_urdf10_description/urdf/. I will update this as soon as possible.
This hasn’t been updated yet 
There is no urdf10_description.urdf.xacro in updated specified directory. Even though I run rviz and set to base link, it give me no transform error when I add robot model, how can i fix this problem?
Hello all,
The correct command to use is the following:
cp /home/simulations/public_sim_ws/src/all/open_manipulator_tc/assem_urdf10_description/urdf/assem_urdf10_good.urdf.xacro ~/catkin_ws/src/
This should be fixed in the notebook as well. Sorry for the inconvenience.
