[ros-users] spawning objects in gazebo with launch script

Hello all,

Is there a way to spawn objects in the PR2 Gazebo simulator without having
them fall from the sky?

I'm trying to spawn a table and some cups in front of the PR2 without having
them fall on the robot (its arms in particular). I've tried to change the Z
values, but it seems that this does not have any effect on the objects
falling.

Any suggestions would be helpful.

Thanks!
