# LAFAN1 Retargeting Dataset

<video controls autoplay src="https://cdn-uploads.huggingface.co/production/uploads/67639932ad38702e6c8d16d9/V7InyG4CAh5NhUXILTK9b.mp4"></video>

To make the motion of humanoid robots more natural, we retargeted [LAFAN1](https://github.com/ubisoft/ubisoft-laforge-animation-dataset) motion capture data to [Unitree](https://www.unitree.com/)'s humanoid robots, supporting three models: [H1, H1_2](https://www.unitree.com/h1), and [G1](https://www.unitree.com/g1). This retargeting was achieved through numerical optimization based on [Interaction Mesh](https://ieeexplore.ieee.org/document/6651585) and IK, considering end-effector pose constraints, as well as joint position and velocity constraints, to prevent foot slippage. It is important to note that the retargeting only accounted for kinematic constraints and did not include dynamic constraints or actuator limitations. As a result, the robot cannot perfectly execute the retargeted trajectories.

# How to visualize robot trajectories?

```shell
# Step 1: Set up a Conda virtual environment
conda create -n retarget python=3.10
conda activate retarget

# Step 2: Install dependencies
conda install pinocchio -c conda-forge
pip install numpy rerun-sdk trimesh

# Step 3: Run the script
python rerun_visualize.py
# run the script with parameters:
# python rerun_visualize.py --file_name dance1_subject2 --robot_type [g1|h1|h1_2]
```

# Dataset Collection Pipeline

This database stores the retargeted trajectories in CSV format. Each row in the CSV file corresponds to the original motion capture data for each frame, recording the configurations of all joints in the humanoid robot in the following order:
