Could you describe a bit more the inconsistencies that you are getting ?
I was also having some trouble with data consistency and the GetPose3d
method generally seemed to be more reliable than GetPose2d. However, I
was using the SVN trunk of Gazebo and was getting different results
with different revisions. One revision where both GetPose3d and
GetPose2d seemed to work well was r7127.
