Status explanation and documentation

[875140705]

Hello, could you please explain the meaning of each component of the state in "PandaPushJointsDense-v3"? I see that each state consists of three parts: observation (shape = (18,)), achieved_goal (shape = (3,)), and desired_goal (shape = (3,)). However, I haven't found the specific meanings of these components. For example, what do the 18 elements in observation represent? Which one in the Push task remains constant (i.e., the target position of the object)? And which one represents the object (as opposed to the Panda robotic arm)?

Is there any detailed documentation available?
