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. ## Datasets ### robomimic — proficient-human (`ph`, low_dim source), re-rendered | dataset | frames | |---|---| | `robomimic_can` | 23,207 | | `robomimic_lift` | 9,666 | | `robomimic_square` | 30,154 | | `robomimic_tool_hang` | 95,962 | | `robomimic_transport` | 93,752 | ### MimicGen — reset-distribution levels | dataset | frames | | dataset | frames | |---|---|---|---|---| | `mimicgen_coffee_d0` | 223,130 | | `mimicgen_square_d0` | 153,477 | | `mimicgen_coffee_d1` | 224,403 | | `mimicgen_square_d1` | 152,400 | | `mimicgen_coffee_d2` | 224,204 | | `mimicgen_square_d2` | 153,112 | | `mimicgen_coffee_preparation_d0` | 689,273 | | `mimicgen_stack_d0` | 107,590 | | `mimicgen_coffee_preparation_d1` | 687,674 | | `mimicgen_stack_d1` | 108,233 | | `mimicgen_hammer_cleanup_d0` | 285,359 | | `mimicgen_stack_three_d0` | 254,810 | | `mimicgen_hammer_cleanup_d1` | 286,847 | | `mimicgen_stack_three_d1` | 255,096 | | `mimicgen_kitchen_d0` | 616,751 | | `mimicgen_threading_d0` | 224,508 | | `mimicgen_kitchen_d1` | 619,273 | | `mimicgen_threading_d1` | 223,115 | | `mimicgen_mug_cleanup_d0` | 338,136 | | `mimicgen_threading_d2` | 227,084 | | `mimicgen_mug_cleanup_d1` | 338,034 | | `mimicgen_three_piece_assembly_d0` | 336,695 | | `mimicgen_nut_assembly_d0` | 358,907 | | `mimicgen_three_piece_assembly_d1` | 334,869 | | `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.
