|
| Welcome to **LIBERO-GeoMotion**! This repository provides a standalone LIBERO-based environment for evaluating robot manipulation under geometric constraints: moving through narrow passages, placing objects with a required orientation, avoiding obstacles, and closing drawers or cabinet doors after storage. |
|
|
| LIBERO-GeoMotion was introduced in our paper [Large Multimodal Models for Direct Robot Control: GPT-6 as a Beginning](https://arxiv.org/abs/2610.28259). See the [GPT-GEAR repository](https://github.com/6UOOON9/GPT-GEAR) for the accompanying robot control and evaluation framework. |
|
|
| The distribution includes the simulation runtime, scene definitions, required base assets, fixed initial states, and six expert demonstrations. **You can install and run it directly, without a separate LIBERO-plus checkout or asset download.** MuJoCo, robosuite, and other Python dependencies are installed by pip. |
|
|
| Start with one scene to check your installation, then run the full scene checks or connect your own policy through the Python API. |

|
|
| ## 🔧 Installation |
|
|
| ### 1. Prepare the system |
|
|
| | Component | Requirement | |
| |---|---| |
| | Operating system | Linux; the system package commands below target Ubuntu / Debian | |
| | Python | **3.12**; the package requires `>=3.12,<3.13` | |
| | Python environment | A dedicated virtual environment to keep simulator dependencies separate | |
| | Default rendering | OSMesa for offscreen rendering without a display or GPU | |
| | Optional GPU rendering | EGL with a working GPU driver and EGL runtime | |
|
|
| Install the OSMesa and ImageMagick system libraries: |
|
|
| ```bash |
| sudo apt-get update |
| sudo apt-get install -y libosmesa6 libmagickwand-dev |
| ``` |
|
|
| OSMesa provides the default rendering backend; ImageMagick is used by the bundled image-processing code through Wand. These system libraries are required in addition to the Python packages. |
|
|
| The following steps assume `python3.12` is available and supports `venv`. If your distribution packages virtual-environment support separately, install its matching `python3.12-venv` package first. |
|
|
| ### 2. Install the environment |
|
|
| Download or clone this repository, open a terminal in its root directory, and run: |
|
|
| ```bash |
| python3.12 -m venv .venv |
| source .venv/bin/activate |
| python -m pip install --upgrade pip |
| python -m pip install -e . -c constraints-tested.txt |
| geomotion --help |
| ``` |
|
|
| [`constraints-tested.txt`](constraints-tested.txt) records the validated Linux dependency versions. Passing it with `-c` constrains the packages needed by this project; it does not install every package listed in the file. The editable install (`-e .`) uses the code and assets in this checkout, so keep the repository in place. |
|
|
| In each new terminal, run `source .venv/bin/activate` again from the repository root. This distribution provides the `libero` Python namespace; keep other LIBERO installations in separate environments. |
|

|
|
| ## ✅ Verify your installation |
|
|
| ### 1. Check installation |
|
|
| ```bash |
| geomotion doctor |
| ``` |
|
|
| The command loads the task suite and reports dependency versions. A successful JSON result contains `"passed": true`, `"tasks": 36`, and reference IDs `[0, 4, 8, 26, 28, 34]`. It does not create a simulation scene or test rendering. |
|
|
| ### 2. Run your first scene |
|
|
| ```bash |
| geomotion smoke --ids 0 |
| ``` |
|
|
| This creates task 0, restores its fixed initial state, checks both 256 × 256 camera images, and executes one action. A successful result contains `"passed": true`, `"initial_state_error": 0.0`, and an `elapsed_seconds` value close to `0.05` (20 Hz control). |
|
|
| **No viewer window opens:** the check renders offscreen. `success_after_one_step` reports task completion after that single action; `false` is normal and does not mean the installation failed. |
|
|
| ### 3. Check all scenes and replay the experts |
|
|
| Once the first scene works, you can run the broader checks: |
|
|
| ```bash |
| geomotion smoke --ids all --output validation/smoke.json |
| geomotion replay-experts --ids all --output validation/experts.json |
| ``` |
|
|
| The smoke command checks all 36 scenes. Expert replay checks the **six included demonstrations**, verifies their initial states, and executes their recorded actions through the simulator. Each successful replay reports `"success": true`. Replay takes longer than a single smoke check and runs without camera observations. |
|
|
| Use comma-separated IDs for a smaller selection, such as `geomotion smoke --ids 0,4,8`. For `replay-experts`, only IDs `0,4,8,26,28,34` are available. The optional `--output` writes a JSON report after a successful check. |
|
|
| ### Optional: use GPU rendering |
|
|
| The CLI defaults to OSMesa. If your machine has a working EGL setup, select it explicitly: |
|
|
| ```bash |
| geomotion smoke --ids 0 --renderer egl |
| ``` |
|
|
| In Python, use `geomotion.make_env(0, renderer="egl")` before importing MuJoCo or other OpenGL-dependent modules. Switch renderers in a fresh process; in a notebook, restart the kernel first. |
|
|
| <a id="python-api"></a> |
|
|
| ## 🐍 Python API |
|
|
| This minimal example loads one scene, prints its instruction and image shapes, executes one stationary command with the gripper open, and closes the environment: |
|
|
| ```python |
| import geomotion |
| |
| suite = geomotion.get_suite() |
| print("Tasks:", suite.n_tasks) |
| print("Instruction:", suite.get_task(0).language) |
| |
| env, obs = geomotion.make_env(0) |
| try: |
| print("Agent view:", obs["agentview_image"].shape) # (256, 256, 3) |
| print("Wrist view:", obs["robot0_eye_in_hand_image"].shape) # (256, 256, 3) |
| action = [0, 0, 0, 0, 0, 0, -1] |
| obs, reward, done, info = env.step(action) |
| print("Task success:", bool(env.check_success())) |
| finally: |
| env.close() |
| ``` |
|
|
| For policy evaluation, replace the example action with your policy output and repeat for at most **4,000 actions**, stopping as soon as `env.check_success()` is true. The example action only exercises the interface; it is not a task-solving policy. |
|
|
| Actions are seven native `OSC_POSE` control values in `[-1, 1]`: three translation components, three rotation components, and one gripper command (`-1` opens; `+1` closes). Use `geomotion.make_env(task_id)` for each new episode to restore the packaged initial state. Calling bare `env.reset()` does not restore that state. |
|
|
| By default, runtime configuration is written under `~/.cache/libero-geomotion/` (or `$XDG_CACHE_HOME/libero-geomotion/`), in a directory specific to the installation. You can set `config_dir` in `make_env()` to choose another directory. If `LIBERO_CONFIG_PATH` is already set, the runtime uses that directory unless `config_dir` is supplied. |
|
|
| <a id="evaluation"></a> |
|
|
| ## 📐 Tasks and evaluation |
|
|
| Task IDs are fixed from **0 to 35**. The published suite is `libero_rp`. |
|
|
| | Task family | Task IDs | |
| |---|---| |
| | Narrow-Passage Transport | 0–3 | |
| | Upright Book Placement | 4–7 | |
| | Oriented Bottle Placement | 8–11 | |
| | Plate Pushing Around Obstacles | 12–15 | |
| | Book Storage in a Drawer | 16–19 | |
| | Single-Mug Alignment and Closure | 20–23 | |
| | Mango Transport and Avoidance | 24–27 | |
| | Package Storage and Drawer Closure | 28–33 | |
| | Dual-Mug Alignment and Closure | 34–35 | |
|
|
| The default evaluation settings are: |
|
|
| | Setting | Value | |
| |---|---| |
| | Robot and controller | Panda, delta `OSC_POSE` | |
| | Initialization | Fixed initial state 0, seed 0, no warmup steps | |
| | Control frequency | 20 Hz | |
| | RGB observations | `agentview` and `robot0_eye_in_hand`, each 256 × 256 | |
| | Episode budget | 4,000 native actions | |
| | Termination | Stop on `env.check_success()` or the action budget; do not rely on `done` | |
|
|
| Success uses the official task predicates, including placement, orientation, release, stability, door/drawer state, and task-specific process or safety constraints. Simulator geometry, object poses, and predicate internals are evaluator-only information; policy inputs are the task instruction, camera images, robot proprioception, and explicitly selected references. |
|
|
| Report per-scene and per-family success, and distinguish the overall scene mean from the family macro-average because family sizes differ. See the [`evaluation_protocol.json`](geomotion/resources/evaluation_protocol.json), [`task_families.json`](geomotion/resources/task_families.json), and [task manifest](libero_rotation_planning/benchmark/task_manifest.json) for the complete settings and task descriptions. |
|
|
| ## 🎬 Expert demonstrations |
|
|
| The suite contains **9 task families: 6 have one reference demonstration each, and 3 have no reference demonstration**. The six demonstrations are bundled under [`geomotion/resources/expert_reference/`](geomotion/resources/expert_reference/), for scene IDs **0, 4, 8, 26, 28, and 34**. Each matches its own test scene's fixed initial state. The 3 families without reference demonstrations are **Plate Pushing Around Obstacles, Book Storage in a Drawer, and Single-Mug Alignment and Closure**. Make the reference selection explicit when reporting evaluation results. |
|
|
| To export the included HDF5 demonstrations into portable videos, text, and trajectories: |
|
|
| ```bash |
| geomotion export-references --ids all --output ./geomotion-references-256 |
| ``` |
|
|
| Each `task_NNN/` directory contains lossless `agentview.mp4` and `wrist.mp4`, each 256 × 256, `videos.json`, `trajectory.json` / `trajectory.jsonl`, and the original expert instructions (`steps.md`). Export renders every saved pre-action state at the evaluation resolution and reconstructs grip-site poses without stepping physics. The final trajectory record has a null action. |
|
|
| Use `--ids 0,4` to export a subset. Existing `task_NNN/` directories are never overwritten; choose a new output directory for another export. |
|
|
| In the packaged HDF5 demonstrations, observations and simulator states precede each paired action; rewards and success flags follow it. Runtime scene loading uses the packaged BDDL and assets. The six files in `expert_reference/text/` contain demonstration steps and measured keypoints, and supply the exported `steps.md`. |

| <a id="troubleshooting"></a> |
|
|
| ## 🛠️ Troubleshooting |
|
|
| | Symptom | What to check | |
| |---|---| |
| | pip rejects the Python version | Run `python --version` inside the active environment. This release requires Python 3.12. | |
| | `geomotion: command not found` | Activate `.venv` and repeat the editable install with that environment's `python -m pip`. You can also use `python -m geomotion.cli --help`. | |
| | OSMesa cannot load, or OpenGL initialization fails | Check that `libosmesa6` is installed in the system or container running Python. Try `geomotion smoke --ids 0 --renderer osmesa` in a fresh process. | |
| | Wand cannot find ImageMagick / MagickWand | Install `libmagickwand-dev` in the system or container running Python. | |
| | EGL initialization fails | Check the GPU driver and EGL availability inside the runtime. Use `--renderer osmesa` to run without GPU rendering. | |
| | `renderer is already initialized` or `LIBERO config already initialized` | Start a fresh Python process or restart the notebook kernel, and configure GeoMotion before importing the simulator. | |
| | Expert ID is rejected | Replay and export support only `0,4,8,26,28,34`; smoke checks support all IDs from 0 to 35. | |
|
|
| When reporting a problem, include the command you ran, the full traceback, your OS and Python version, the selected renderer, and the `geomotion doctor` output if it runs successfully. This makes installation issues easier to reproduce. |
|
|
| ## 📦 Building a wheel (optional) |
|
|
| For an installation that does not depend on the source checkout, build a wheel from the repository root: |
|
|
| ```bash |
| python -m pip install build |
| python -m build |
| ``` |
|
|
| Install the resulting wheel in a fresh Python 3.12 environment with `python -m pip install /path/to/libero_geomotion-0.3.0-py3-none-any.whl`. The wheel includes the packaged scene assets and demonstrations. The system libraries from the installation section are still needed; rerun `geomotion doctor` and `geomotion smoke --ids 0` after installation. |
