Problem running pick and place application tutorial

edit

I've got the same problem recently, but there was no such problem before. The default setting is to use the stereo camera and I've write a simple node to make PR2 look down. But the problem still exists. How to fix this problem? Thanks

You're using the stereo camera and looking at the table and it says Call to segmentation service failed? Any other error messages around it? Which ROS distro are you using?

I've checked the pr2_tabletop_manipulation.launch, and the value of arg stereo is true, which will set thetabletop_segmentation_points_input as narrow_stereo_textured/points2. I put the error messages here: http://notepad.cc/dedoucle19 and the brief description is below. My ROS distro is Fuerte

The object segmentation service can segment out the table. The INFO shows that "Step 4 done" and "Table computed". But after that, there seemed to be some internal problems which threw out the error message "Call to segmentation service failed", and then the tabletop_segmentation node died.

Hrm. That's odd. Fuerte debians, latest version? Are you using shadow-fixed or public repos? What version of Ubuntu? 64-bit or 32-bit? I just tried using pr2_table_object.launch, both stereo:=true and stereo:=false, and both worked fine on my laptop.

There have been some build-farm compilation issues with compile flags lately, that might be causing the undefined-symbol problems you're seeing. Try just compiling and using object_manipulation and pr2_object_manipulation from source.

I'm using Fuerte on Ubuntu 12.04 64-bit and the package is installed using apt-get. I've already upgrade all the package to the latest version. I don't know what is the difference between using shadow-fixed or public repos. Also, what is build-farm compilation issues with compile flags lately mean?

I'm guessing you're using the public repos (http://packages.ros.org/ros/ubuntu) then. When http://ros.org/debbuild/fuerte.html shows FbinP64 for perception_pcl having a green box (mouseover the green box should read ros/Public 1.2.4) then the new release of perception_pcl will be done building.
