| # Model Card for molmoact2 |
|
|
| <!-- Provide a quick summary of what the model is/does. --> |
|
|
|
|
| [MolmoAct2](https://allenai.org/blog/molmoact2) is an open robotics foundation model from the Allen Institute for AI (Ai2) that maps camera images and language instructions to robot action chunks. The LeRobot implementation supports training and evaluation of the regular MolmoAct2 model. |

|
| ## How to Get Started with the Model |
|
|
| New to LeRobot? These guides cover the full workflow: |
|
|
| - **[Install LeRobot](https://huggingface.co/docs/lerobot/main/en/installation)** — set up the `lerobot` package. |
| - **[Hardware setup](https://huggingface.co/docs/lerobot/main/en/hardware_guide)** — assemble, wire, and calibrate your robot and cameras. |
| - **[Record data & train a policy](https://huggingface.co/docs/lerobot/en/il_robots)** — the end-to-end imitation-learning walkthrough. |
| - **[CLI cheat-sheet](https://huggingface.co/docs/lerobot/main/en/cheat-sheet)** — quick reference for the `lerobot-*` commands. |
|
|
| The short version to run and train this policy: |
|
|
| ### Run the policy on your robot |
|
|
| ```bash |
| lerobot-rollout \ |
| --strategy.type=base \ |
| --robot.type=so_follower \ |
| --robot.port=<your_robot_port> \ |
| --robot.cameras="{ <camera_1>: {type: opencv, index_or_path: <index_or_path>, width: 640, height: 480, fps: 30}, <camera_2>: {type: opencv, index_or_path: <index_or_path>, width: 640, height: 480, fps: 30}}" \ |
| --policy.path=justintiensmith/molmoact2_500eps_endeffector_trace \ |
| --task="Drag the cloth across the table." \ |
| --duration=60 |
| ``` |
|
|
| Replace the remaining `<...>` placeholders with your own values: `--robot.port` and the camera names/indices are specific to your machine, and the camera names must match the observation keys this policy was trained on. |
|
|
| When `--strategy.type=base` is used the script doesn't record the episodes. Skipping duration will make the policy run indefinitely. For more information look at [rollout documentation](https://huggingface.co/docs/lerobot/main/en/inference). |
|
|
| ### Train your own policy |
|
|
| ```bash |
| lerobot-train \ |
| --dataset.repo_id=${HF_USER}/<dataset> \ |
| --policy.type=molmoact2 \ |
| --output_dir=outputs/train/<policy_repo_id> \ |
| --job_name=lerobot_training \ |
| --policy.device=cuda \ |
| --policy.repo_id=${HF_USER}/<policy_repo_id> \ |
| --wandb.enable=true |
| ``` |
|
|
| _Writes checkpoints to `outputs/train/<policy_repo_id>/checkpoints/`._ |
|
|

|
|
| ## Evaluation |
|
|
| <!-- Report real-robot results here: run the policy several times per task and count the |
| successes. Delete the "No evaluation results" line and fill in this table instead: |
|
|
| | Task | Trials | Successes | Success rate | |
| | ---- | ------ | --------- | ------------ | |
| | pick the lego brick | 10 | 8 | 80% | |
|
|
| Also worth noting: anything that affects difficulty (new object positions, lighting, |
| distractors, a different robot of the same type, ...). |
