Hello all,<br><br>Is there a way to spawn objects in the PR2 Gazebo simulator without having them fall from the sky?  <br><br>I&#39;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&#39;ve tried to change the Z values, but it seems that this does not have any effect on the objects falling.<br>
<br>Any suggestions would be helpful.<br><br>Thanks!<br><br>Mario Bollini<br>
