how to call pause_physics service
i cant seem to do:
pause_physics_client=rospy.ServiceProxy('/gazebo/pause_physics',PausePhysics)
there doesn't seem to be a PausePhysics.srv anywhere under gazebo_msgs/srv
I can see that the service is running in rosservice list, and I'm using groovy.
What should I be doing instead? All I want is a way to toggle physics inside my code.
