UMI-on-Air - Pre-trained Checkpoints

Pre-trained diffusion policy checkpoints for UMI-on-Air: Embodiment-Aware Guidance for Embodiment-Agnostic Visuomotor Policies.

UMI-on-Air is a framework for embodiment-aware deployment of embodiment-agnostic manipulation policies. It leverages diverse, unconstrained human demonstrations to train generalizable visuomotor policies that can be adapted to constrained robotic embodiments at inference time.

Checkpoints Included

Task	Description
`umi_cabinet`	Cabinet door opening task
`umi_peg`	Peg insertion task
`umi_pick`	Object picking task
`umi_valve`	Valve turning task

Usage

1. Download and Extract

bash

# Download and extract the checkpoints
wget https://huggingface.co/LeCAR-Lab/umi-on-air_checkpoints/resolve/main/checkpoints.tar.gz
tar -xzf checkpoints.tar.gz

Each checkpoint folder contains:

checkpoints/latest.ckpt - Model weights
normalizer.pkl - Data normalization parameters
.hydra/config.yaml - Training configuration

2. Policy Evaluation

After setting up the environment according to the official repository, you can evaluate a policy in simulation with Embodiment-Aware Diffusion Policy (EADP) guidance.

For example, to evaluate the Unmanned Aerial Manipulator (UAM) on the cabinet task with guidance:

bash

cd am_mujoco_ws/policy_learning
python imitate_episodes.py \
    --task_name uam_cabinet \
    --num_rollouts 30 \
    --guidance 1.5 \
    --use_3d_viewer
