Meaning of the 28-Dimensional Action Space in LeRobot Format

[BaiShuanghao]

Hello, I would like to ask: in the LeRobot format, the action vector has 28 dimensions — what does each dimension represent?

Thank you in advance for your help!

The action dimension is the concatenation of (7-DoF left-hand, 7-DoF right-hand, 7-DoF left-arm, 7-DoF right-arm). The values are all joint angles.
