I am in section 3-Using URDF for Gazebo, and I have a problem trying to launch my file “start_mira_with_onecontroller.launch”, to spawn my Mira URDF model into Gazebo only with the roll_joint controller. When I try to launch this file, the webshell shows me this:
I don’t know what does this means. I have followed the notebook instructions until this point, and I got stuck here. I am using the files from the notebook (start_mira_with_onecontroller.launch, mira_onejoint_control.launch, spawn_mira_with_onecontroller.launch, mira_control.yaml, mira_with_onecontroller.urdf) but I don’t know what happens. If someone could help me, I would really appreciate it.
Thanks a lot.
