Model Description

FingerNet-Surf is an MLP model designed for the asFinger with a contact surface. It can predict both 6D force and 3D shape (mesh nodes) from the 6D motion of the asFinger.

Try it out on the Spaces Demo!

Intended Use

This model is intended for researchers and developers working in robotics and tactile sensing. It can be used to enhance the capabilities of asFingers in applications such as robotic manipulation, haptics, and human-robot interaction.

See the project page for more details.

To load the model:

# Example code to load safetensors
from transformers import AutoModel

model = AutoModel.from_pretrained("asRobotics/fingernet-surf", trust_remote_code=True)
x = torch.zeros((1, 6))  # Example input: batch size of 1, 6D motion
output = model(x)

Or to load the ONNX version:

# Example code to load onnx
import onnxruntime as ort
import numpy as np
from huggingface_hub import hf_hub_download

onnx_model_path = hf_hub_download(repo_id="asRobotics/fingernet-surf", filename="model.onnx")
ort_session = ort.InferenceSession(onnx_model_path)
x = np.zeros((1, 6)).astype(np.float32)  # Example input: batch size of 1, 6D motion
outputs = ort_session.run(None, {"motion": x})

Training Data

The model was trained on the FingerNet-100K, which includes a variety of motion, force, and shape data collected by finite element simulations.
