URDF to Collada: joint coordinate system not observed?

Open sloretz opened this issue 7 years ago • 11 comments

From ros/robot_model#169

I have a problem similar to this http://answers.ros.org/question/221675/unable-to-move-links-within-urdf-file/ , it is only that I convert from URDF to Collada.

Original URDF as seen in RViz: head_mm_urdf

After converting to Collada as seen in Openrave: head_mm_loose_dae

If I judge solely by eyesight, it seems to me that in the converted Collada file the visual elements are rendered not w.r.t. (local) joint coordinate systems.

I am using Indigo:

$ dpkg -l | grep indigo-collada
ii  ros-indigo-collada-parser                             1.11.11-0trusty-20160627-175110-0700                amd64        This package contains a C++ parser for the Collada robot description format.

Is this a known problem, maybe, already solved in Kinectic?

Thanks.
