I am not quite sure what exactly you are trying to do. Transforms (called “frames” in Chrono) can be concatenated and so you can express whatever frame into another one. Do you want to express the wheel frame into the chassis COG frame? Something else? And when you say “it seems to have failed” what does that mean?

Now I want to get the motion data of vehicle subsystems by invoking function GetState() in ChWheel. Unfortunately, the motion data I got was expressed in global reference frame, and I have tried using TransformParentToLocal to transform the rotation quaternion into COG reference, it seems to have failed. Any advice will be appreciated! Chao -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
