Is this still an attempt?

If not. I have a issue.

I tried all combination around sign corrections but I will not solve the orientation error.
Should I change URDF definition ?

We made the self-check a two step process to be able to debug a mismatch between opw parameters and URDF more easily.

First all 0 is checked and it fails here. Sign corrections do not have any influence for the all-0 position. You don't have an error about a pose position so your distances and most of the offsets appear to be correct. Maybe your last frame is oriented differently? Or has some joint offset?

Do you have a link to the robot and it's URDF?

Thanks for your kindly reply.Here is my respiratory;https://github.com/AltinayGrass/sr80_moveit_config/tree/noeticOn Nov 5, 2022 23:49, Simon Schmeisser ***@***.***> wrote: We made the self-check a two step process to be able to debug a mismatch between opw parameters and URDF more easily.

Hello Simon, I checked my 3D data and URDF file. Robot has more than one rotation axis on its links. Could this the cause of the error?
