[PLR] String Shooter (Lasso) Identification

Repo Structure

  • workflows:

    • contour_from_img.py: Tool to extract the raw string contour from a given image and store it in an npy file
    • fitting.ipynb: Notebook in which the model from paper "String Shooter’s overall shape in ambient air" is fit to the raw contour. Currently, this has to be done manually.c:w
  • string_shooter_identification: Python package

    • vision: utils to extract contours from image
    • shape: shape interpolation between different contours
  • notebooks: some preliminery work to get a feel for the topic

  • gym: contains simulation script to demonstrate the curve fitting and interpolation at different angles, as well as the necessary urdf file

How to run

pip install -e .
python3 gym/sim_with_shape_controller.py
