==>> So, if we only use X,Y,Z values, how about Rx, Ry, Rz? Are they zero values or we can set it with fix values by ourself? 

- In the code flow for retrieving process, ShiftGripperPose returns the moving poses (Figure 1), but in ShiftGripperPose function, it non-returns Rx, Ry, Rz. For that reason, the moving poses have zero values

With zero values, it cannot grasp objects.
