| # Merged DROID Skill Dataset: stacking |
|
|
| This dataset merges a language-filtered DROID skill subset with newly collected |
| environment data for the same skill. |
|
|
| ## Repository |
|
|
| - Hugging Face repo: `jellyho/droid_merged_skills_stacking` |
| - Local merged dataset path: `/scratch/jellyho/droid_merged_skills/stacking` |
| - Skill: `stacking` |

| ## State And Action |
| |
| The compact LeRobot training fields are standardized as 8D vectors: |
| |
| ```text |
| 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. |
