I use function "void AttachStaticModel (ModelPtr &_model, math::Pose _offset)" to attach model A to model B. Model A is not static(it can move), so I also use void SetStatic (const bool &_static) to set model A to be static. However, it is not successful because when model B moves, model A does not follow but stay still.

I am using Gazebo 5.0. Any suggestion?
