what dose "action"，"effector_translation" and "effector_target_translation" mean?
"action": "description": "An action representing a 2D delta cartesian setpoint for the robot." "effector_translation": "description": "The current end effector translation as a 2D cartesian coordinate." "effector_target_translation": "description": "The target location for the end effector as a 2D cartesian setpoint."
Hi, thanks for your great job! The description of the dataset is pretty ambigous for me. What do ”cartesian setpoint for the robot“, "end effector translation " and "location for the end effector " mean? Are they describe the same thing (robot arm end effector)?
Thanks for your attention and I am waiting for your kind response.
"action" is the relative movement from the current to the target position. It is described as "delta cartesian setpoint", since it's the difference ("delta") from current cartesian setpoint ("effector_translation") to target cartesian setpoint ("effector_target_translation").
We are always and only talking about different (absolute and relative) positions of the end effector here.

@felixmin Thanks for your answer!
But in the datasets, the "action" are not the difference between "effector_translation" and "effector_target_translation".
and why the "effector_target_translation" in time_0 is not the same as "effector_translation" in time_1
as shown below:
In each line, the two-dimensional vectors are respectively "action", "effector_translation" and "effector_target_translation".
Thanks for your attention and I am waiting for your kind response too.
@HARVEYDOU Hi, I have the same question with you. Have you solved the problem? If so, could you please share the answer of it. Thanks a lot.
@ZhefeiGong Sorry. I have turned to other work, and this question is still not solved.
