Hi all,

I'm still trying to get the manipulation stack to work with our arm and hand
and I ran into some problem:

As you can see here, A path from pregrasp to grasp is found:

 > the path seems to be the wrong way around: the first markers are at the
bottom, instead of at the top.
 > when moving the arm, the arm moves maybe 5cm below the markers (on the
screenshot, it's at position 0 which should be pregrasp).

The values I put in the database are:
grasp_pregrasp_position =
grasp_grasp_position =

Any help greatly appreciated.
