Hello,

I am working with hector_quadrotors and trying to spawn two of them into gazebo. I took also two namespaces for them and the spawning works. But unfortunately if I am spawning both of them, they crash and fly in different directions. One of them is standing with downside up.

I got this Error-messages

-Tried to advertise a service that is already advertised in this node [/raw_imu/calibrate]

-Tried to advertise a service that is already advertised in this node [/rawimu/setaccel

-Tried to advertise a service that is already advertised in this node [/rawimu/setrate_

I also tried to list the services with "rosservice list" and checked, if all of them are in different namespaces. But the rosservice /raw_imu/calibrate is not in a seperate namespace. Thats really weird.

I also worked with fuerte and in fuerte it worked, but since I changed to groovy it doesnt work and I dont know why. I dont know how to put raw_imu into a different namespace.

Anyone have an idea or a direction I can go to figure out what is happening? Thanks in advance!
