Questions about VR device

[nikepupu]

The platform I am using does not have VR support, So I am reading everything from openvr using steamvr.

I would really appreciate if you can help me out here.

what is the purpose of
self.gripper_position_offset
and
self.gripper_orientation_offset

Are they initial positions and orientations for the robot gripper in the world?

I try to set up vr control on my platform. However, I found out that a rotation in vr device does not match a rotation in the game.
Are these variables supposed to help with this situation?
