# robosuite + LeRobot manipulation demonstrations (Lance, 3-view)

**239 manipulation datasets** in the
[Lance](https://lancedb.github.io/lance/) format, across seven collections:

| directory | datasets | contents |
|---|---|---|
| `libero/` | 130 | [LIBERO](https://libero-project.github.io)-130 tasks (90 + 10 + object + spatial + goal) |
| `robocasa/` | 65 | [RoboCasa](https://robocasa.ai) atomic kitchen tasks |
| `mimicgen/` | 26 | [MimicGen](https://mimicgen.github.io) task/level variants |
| `dexmimicgen/` | 9 | [DexMimicGen](https://dexmimicgen.github.io) bimanual dexterous tasks |
| `robomimic/` | 5 | [robomimic](https://robomimic.github.io) proficient-human tasks |
| `ogbench/` | 2 | `ogb_cube_single`, `ogb_scene_single` |
| `molmo_obj_mug/` | 2 | `molmo_obj_mug`, `molmo_obj_mug_videos` |

The five replay-rendered collections hold ≈ **14.11M frames**. Every dataset is
a single-version `<name>.lance/` directory under its collection.

These are **source demonstrations, not policy rollouts**. robomimic, MimicGen,
LIBERO and DexMimicGen were replayed in robosuite from recorded MuJoCo states and
re-rendered to 224×224 from three camera views. RoboCasa ships as pre-rendered
[LeRobot](https://github.com/huggingface/lerobot) videos (v0.2), so its three
views are decoded directly from those videos (no replay) and resized to 224×224
for consistency.

## Cameras (3 views)

Every step carries three JPEG-encoded 224×224 RGB views, in a
two-exterior-plus-wrist layout:

| column | robomimic / MimicGen / LIBERO | RoboCasa | role |
|---|---|---|---|
| `pixels` | `agentview` | `robot0_agentview_left` | primary exterior |
| `sideview` | `sideview` | `robot0_agentview_right` | second exterior |
| `robot0_eye_in_hand` | wrist | `robot0_eye_in_hand` | in-hand / eye-in-hand |

The PickPlace-family envs (`mimicgen_pick_place_d0`, `robomimic_can`) do not define
a `sideview` camera natively, so the standard robosuite world-level `sideview` is
injected at render time. All replay-rendered datasets therefore share the same
three views; RoboCasa's three come from its native left/right/wrist LeRobot videos.

## Schema

All datasets share the framework columns below:

| column | type | meaning |
|---|---|---|
| `episode_idx` | int32 | episode index |
| `step_idx` | int32 | step within episode |
| `pixels` / `sideview` / `robot0_eye_in_hand` | binary (JPEG) | the three 224×224 RGB views |
| `action` | float[] | controller action (robosuite 7-dim single-arm / 14-dim bimanual; RoboCasa 12-dim) |
| `state` | float[] | per-step state vector |
| `reward` | float[1] | task reward (sparse) |
| `terminated` / `truncated` / `success` | float[1] | episode-end / success flags |

Replay-rendered sources (robomimic, MimicGen, LIBERO) additionally carry
`qpos` / `qvel` (MuJoCo generalized position / velocity), `render_time`, `id`,
and **each source's own named low-dim observation keys, kept verbatim** — e.g.
robosuite's `robot0_eef_pos`, `object`, …; LIBERO's `ee_pos`, `ee_ori`,
`gripper_states`, `joint_states`. There `state` is the flattened MuJoCo state used
to drive replay.

**RoboCasa differs**: it is derived from LeRobot recordings, not a MuJoCo replay,
so it has no `qpos`/`qvel`/sim-state. Its `state` is the LeRobot 16-dim
`observation.state` proprioception and `action` is the 12-dim LeRobot action.
Each source keeps its own low-dim observation names, so they vary by collection.

### MimicGen — reset-distribution levels

| dataset | frames | | dataset | frames |
|---|---|---|---|---|

| `mimicgen_mug_cleanup_d0` | 338,136 | | `mimicgen_threading_d2` | 227,084 |

| `mimicgen_pick_place_d0` | 677,340 | | `mimicgen_three_piece_assembly_d2` | 335,949 |

The `D0`/`D1`/`D2` suffix is the **environment reset-distribution level**, not a
data-size level. `D0` initializes objects over a region resembling the source
demonstrations; `D1` and `D2` broaden the initial-pose distribution. See the
[MimicGen dataset docs](https://mimicgen.github.io/docs/datasets/mimicgen_corl_2023.html).

### DexMimicGen — `dexmimicgen/` (9 bimanual tasks, 2,915,177 frames)

[DexMimicGen](https://dexmimicgen.github.io) bimanual dexterous tasks (NVIDIA,
ICRA 2025) across three robot configs — bimanual Panda, Panda + dexterous hands
(`PandaDexRH`/`LH`), and the GR1 humanoid — replayed from recorded states. Native
cameras are agentview + two wrist views, so `sideview` is the injected world camera.
`action` is 14-dim (bimanual Panda) or 24-dim (dexterous / GR1); proprio obs keys
span `robot0`/`robot1` (and GR1 `left`/`right`).
