# 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`
- LeRobot codebase version: `v2.0`
## Sources
```json

"jellyho/droid_subsets_stacking",
"jellyho/droid_stack_bar"
]
```
| source_dataset | episodes |
| --- | --- |
| jellyho/droid_subsets_stacking | 300 |
| jellyho/droid_stack_bar | 20 |
## 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.
