MidasTouch performs online global localization of a vision-based touch sensor on an object surface during sliding interactions. For details and further results, refer to our website and paper.

Setup

1. Clone repository

git clone [email protected]:facebookresearch/MidasTouch.git
git submodule update --init --recursive

2. Download YCB-Slide dataset

cd YCB-Slide 
chmod +x download_dataset.sh && ./download_dataset.sh
cd ..

3. Download weights/codebooks

chmod +x download_assets.sh && ./download_assets.sh

4. Setup midastouch conda env

sudo apt install build-essential python3-dev libopenblas-dev
conda env create -f environment.yml 
conda activate midastouch
pip install -e .

5. Install PyTorch and the MinkowskiEngine

      Follow the conda instructions from the NVIDIA MinkowskiEngine webpage

Run MidasTouch

Run interactive filtering experiments with our YCB-Slide data from both the simulated and real-world tactile interactions.

TACTO simulation trajectories

python midastouch/filter/filter.py expt=ycb # default: 004_sugar_box log 0
python midastouch/filter/filter.py expt.obj_model=035_power_drill expt.log_id=3 # 035_power_drill log 3
python midastouch/filter/filter.py expt.off_screen=True   # disable visualization
python midastouch/filter/filter.py expt=mcmaster   # small parts: cotter-pin log 0

Real-world trajectories

python midastouch/filter/filter_real.py expt=ycb # default: 004_sugar_box log 0
python midastouch/filter/filter_real.py expt.obj_model=021_bleach_cleanser expt.log_id=2 # 021_bleach_cleanser log 2

Codebook live demo

With your own DIGIT, you can simple plug in the sensor and experiment with the image to 3D and tactile codes visualizer.

python midastouch/filter/filter_real.py expt.obj_model=025_mug
