Hi all,
I'm using gazebo 7 to simulate a differential drive robot. Following the [ROS tutorials](http://wiki.ros.org/urdf/Tutorials) online, I created an urdf file to describe my robot:
- https://github.com/schizzz8/lucrezio_description/blob/master/urdf/lucrezio.urdf.xacro
If I launch an empty world:
roslaunch gazebo_ros empty_world.launch
and then I spawn the robot with this launch file:
- https://github.com/schizzz8/lucrezio_description/blob/master/launch/robot.launch
everything goes fine.

Now, I wrote a simple plugin for the [logical_camera](http://gazebosim.org/tutorials?tut=logical_camera_sensor&cat=sensors&branch=logical_camera) sensor:
- https://github.com/schizzz8/lucrezio_logical_camera
and I try to mount it on the robot by adding these lines to the urdf:
0.02 5.0 ${60.0*M_PI/180.0} 1.778 true true 10
If I now spawn the robot, this is what happens:

Basically, it seems that the ground plane gets shifted up of one meter.
Can please someone explain me what is happening?
Thanks.
