roslaunch gazebo_worlds empty_world.launch

This should start a gazebo gui. then spawn the object using the�

'rosrun gazebo spawn_model -file `pwd`/object.urdf -urdf -z 1 -model
my_object'

as you did before. For more info, look at the tutorials here

http://www.ros.org/wiki/simulator_gazebo/Tutorials/SpawningObjectInSimulation

Futher, the code segment�

<gazebo reference="my_box">
� �<material>Gazebo/Blue</material>
</gazebo>

just adds color to the object(my_object in this case). More info on this is available on the urdf reference here

http://www.ros.org/wiki/urdf/XML under the gazebo elements

Hello All,

I am using karmic. Also I am a student. I have made an object using urdf and
succeeded to spawn it in RViz. Now I want to spawn this object in gazebo
using that urdf file by executing the following command.

'rosrun gazebo spawn_model -file `pwd`/object.urdf -urdf -z 1 -model
my_object'

but unable to view it in gazebo.

Moreover I just want to know about the following few lines in 'urdf' file. I
have not written these lines in my 'urdf' file.

<gazebo reference="my_box">
� �<material>Gazebo/Blue</material>
</gazebo>

'my_box' is just a link. what should be the procedure to spawn an object
with multiple links.

Thanks in advance,

Regrds,
Ali Abbas
