In the grasping stage, the model only generates hand motions, whereas in the interaction phase both hand and object poses are synthesized.

We introduce the dynamic grasp synthesis task: given an object with a known 6D pose and a grasp reference, our goal is to generate motions that move the object to a target 6D pose.
