How to fix robot being launched upside down? [closed]

edit

Hey all,

I am playing around with the Care-o-Bot (rob@work) 3-2 in simulation, and whenever I launch it:

export ROBOT=raw3-2
roslaunch cob_gazebo robot.launch

It gets spawned in Gazebo upside down. Image below:

I tried rotating it by using the right mouse drag and ctr+right mouse drag, but it just goes back to its original upside-down position.

What can I do to fix this?

Thank you for your time and help!
