MT-Libero-Dataset

Expert demonstrations for MT-Libero-Bench, a GPU-parallel multi-task manipulation benchmark that compiles the 40 LIBERO tasks into a single Isaac Lab vectorised training loop.

The 2000 LIBERO demonstrations are re-packaged here into an Isaac Lab-native state format: alongside the original mujoco actions and proprioception, every file carries the full per-frame physics state of the robot and of every object in the scene. That is what makes the demos usable as more than imitation targets — the simulator can be hard-reset to any step of any demonstration, which is what demonstration-indexed resets, reverse curricula, and demonstration-guided reward tracking all need.

Tasks	40 (4 suites × 10)
Demonstrations	2000 (50 per task)
Transitions	336,575 (≈4.7 h at 20 Hz)
Robot	Franka Panda, 7-DoF arm + parallel gripper
Action space	7-D robosuite OSC_POSE (6-D EE delta + 1 gripper bit)
Scene assets	32 SimReady USD assets, 140 MB
Format	40 HDF5 files (251 MB) + USD tree, 408 MB total
Cameras	none — the demonstrations are state-only

Contents

demos/    40 HDF5 files, one per task — trajectories and per-frame physics state
USD/      32 SimReady assets — the objects and fixtures those scenes contain

The two halves are meant to be used together: the HDF5 files record poses of objects by name, and USD/<name>/ is the geometry that name refers to.

Demo files are named demos/{suite}_task{id}_{task_language}_demo.hdf5, so a suite is one glob: demos/libero_spatial_task*.hdf5.

T is per-demo and ranges from 74 to 516 steps. There is no padding and no length attribute — read actions.shape[0].

Two things that will bite you if unread:

• initial_state/ holds the whole trajectory, not just the first frame — the name is historical.
• obs/ and initial_state/ are the same trajectory offset by two control steps: obs/joint_states[t] == initial_state/…/robot/joint_position[t+2, :7]. actions[t] pairs with initial_state[t].

Conventions

• Units — metres, radians, seconds. Control runs at 20 Hz.
• Quaternions — (w, x, y, z), Isaac Lab convention, throughout.
• Frames — everything under initial_state/ is world frame; obs/ee_states is in the robot base frame and must be composed with initial_state/articulation/robot/root_pose to reach world frame.
• Gripper — actions[:, 6] is +1 to close, the robosuite convention. Isaac Lab's gripper action term uses the opposite sign, so a loader targeting it must invert.
• Robot joints — robot/joint_position has 9 columns: 7 arm, then 2 fingers.

USD assets

USD/ holds the 32 SimReady assets these scenes are built from, converted from LIBERO's original MuJoCo meshes. One directory per asset:

USD/
├── akita_black_bowl/
│   ├── akita_black_bowl.usd          ← reference this
│   ├── textures/texture.png
│   └── .thumbs/256x256/…             Omniverse preview, safe to delete
├── wooden_cabinet/
│   ├── wooden_cabinet.usd
│   ├── wooden_cabinet_cube.usd       sub-part, referenced by the entry point
│   └── textures/…
└── …

Always reference USD/<name>/<name>.usd. A few assets ship extra .usd files next to it — flat_stove has knob.usd and burnerplate.usd, wine_rack has five — which are sub-parts composed by the entry point, not alternatives to it.

Matching an asset to the demonstrations. Object keys in the HDF5 files carry a scene-instance suffix that the directory names do not: initial_state/rigid_object/akita_black_bowl_1 → USD/akita_black_bowl/. Strip the trailing _<n>.

Of the 32, 28 are the objects the demonstrations track by name:

	assets
Articulated (4)	flat_stove, microwave, white_cabinet, wooden_cabinet
Rigid (24)	akita_black_bowl, alphabet_soup, basket, bbq_sauce, black_book, butter, chefmate_8_frypan, chocolate_pudding, cookies, cream_cheese, desk_caddy, glazed_rim_porcelain_ramekin, ketchup, milk, moka_pot, orange_juice, plate, porcelain_mug, red_coffee_mug, salad_dressing, tomato_sauce, white_yellow_mug, wine_bottle, wine_rack

The remaining 4 — floor, kitchen_table, living_room_table, study_table — are static fixtures. They are part of the scene but are not tracked entities, so no pose stream exists for them in the HDF5 files.

The Franka Panda itself is not included; it comes from Isaac Lab's own robot assets.

Provenance and known limitations

These are the original LIBERO demonstrations, collected by human teleoperation in MuJoCo, converted to the Isaac Lab state layout. They are not re-recorded under Isaac Lab, and the conversion is a re-packaging, not a re-simulation.
