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">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);">

<br>Thanks.<br>
