Ping. :) This bug still exists in the latest Debian updates for Hydro Precise 64-bit. It is fixed in source but has not yet made it to the Debian version.

[pirobot]

Closing as fixed.

I know it's offtopic, but do you think you could publish this code somewhere in the MoveIt-Wiki as a tutorial or something?
Your thread here was the single most useful resource to me while trying to understand how to grasp with Python in MoveIt. Sadly, your last posted code snippet was where you grasped thin air and attached the object ;)
It would be awesome if your code would serve as an advanced introduction to grasping in MoveIt.

Bug still reproduces on Ubuntu 12.04 Hydro.

The bug is still reproduced, I am stuck...any idea how to overcome it on hydro and ubuntu 12.04 ?

@dyouakim The fix is released to debs -- and should be fully sync'd as of about 2 weeks ago. Please update your debs.

Thanks a lot for your response, I did "apt-get install ros-hydro-moveit-full" , i had one upgrade and then catkin_make on the moveit folder, but still I am getting the same error on my code. Am I missing something ? sorry I don't have much experience.

[mikeferguson]

The OSRF folks tend to recommend doing a "dist-upgrade" -- I'm not keen on that as it might also pull in things like upgraded kernels. My recommendation for updating ROS is to use:

 sudo apt-get --only-upgrade install ros-hydro-*

This will make sure every already installed ros hydro package is updated to the latest (since all of the ROS packages get sync'ed to public together, this should guarantee ABI compatibility between each package). After this, it is also important to rebuild any catkin workspaces that you have to avoid any ABI compatibility problems.

Awesome , thanks a lot for your quick response, it is working perfectly now !

I am sorry again, but since I did this update, all the picks trials are failing (they were wrorking before), and I get the following
[ INFO] [1424350435.700022600]: IK failed
[ INFO] [1424350435.700694400]: Found a contact between 'target' (type 'Object') and 'forearm' (type 'Robot link'), which constitutes a collision. Contact information is not stored.

I tried to change the reach parameters (even it was working before, and it is quiet similar to the code published here), I removed all other objects in the scene, it looks to me it is finding collision with the object it should pick, because whenever I remove the object and paln to this grasp pose it works fine. Any idea ?

[mikeferguson]

@dyouakim any idea how old your previous debians might have been?

[dyouakim]

I just started beginning of Feburary, so it should not be too old.
