Hm may be the time out value is not long enough?<br><br>I think you can modify it in ros/object_manipulation/object_manipulator/src/tools/mechanism_interface.cpp, line 910.<br><br><div class="gmail_quote">2011/3/1 Manuel Rodríguez <span dir="ltr">&lt;<a href="mailto:mrodriguez@robotnik.es">mrodriguez@robotnik.es</a>&gt;</span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hi all,<br><br>I&#39;m trying to run the .cpp file written in <a href="http://www.ros.org/wiki/pr2_tabletop_manipulation_apps/Tutorials/Writing%20a%20Simple%20Pick%20and%20Place%20Application#Object_Pickup" target="_blank">this tutorial</a> (copy-paste). The arm grasps the object but does not lift it.<br>

<br>The rosrun shell shows this error:<br><span style="color:rgb(255, 0, 0)">[ERROR] [1298982592.493542455, 61.186000000]: The pickup action has failed with result code -3</span><br><br>And the roslaunch shell:<br><span style="color:rgb(255, 0, 0)">[ERROR] [1298982592.492881311, 61.187000000]: Hand posture controller timed out on goal (2)</span><br style="color:rgb(255, 0, 0)">
