Merged DROID Skill Dataset: stacking

This dataset merges a language-filtered DROID skill subset with newly collected environment data for the same skill.

State And Action

The compact LeRobot training fields are standardized as 8D vectors:

observation.state = [joint_position_0..6, gripper_position]
action            = [joint_velocity_0..6, gripper_position]

For original DROID subset rows, action is derived from action.joint_velocity plus action.gripper_position. For newly collected rows, action is derived from observation.joint_velocities[:7] plus the collected gripper position from the original action vector.

Detailed columns such as action.joint_position, action.joint_velocity, action.gripper_position, observation.state.joint_position, and observation.state.gripper_position remain available in the parquet files.
