Question about AIRBOT_MMK2_* datasets' gripper information

[Liang-ZX]

Hi, thanks for your great work. I have a question about AIRBOT_MMK2_* datasets. It seems these datasets don't contain 'gripper_open_scale_state' or related information in it. How can we obtain them? And it seems the shape of 'observation.state' of AIRBOT_MMK2 is 36, how to understand or where to find related material to understand the meaning of each dimension? Thank you so much.

AIRBOT_MMK2 robot uses dex-hand instead of gripper, so there is no gripper data in AIRBOT_MMK2_* datasets.
Descriptions of "observation.state", "action" and other features, can be found in meta/info.json, you can find names of each feature data in this meta file.
