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/Blue 'my_box' is just a link. what should be the procedure to spawn an object with multiple links. Thanks in advance, Regrds, Ali Abbas -- View this message in context: http://ros-users.122217.n3.nabble.com/how-to-spawn-an-object-in-gazebo-tp2205680p2205680.html Sent from the ROS-Users mailing list archive at Nabble.com.
