Python interface to Franka robots for Positronic project

Interface to Franka robots for Positronic library

This repository is supposed to be used as a part of positronic package, rather than a standalone project.

Dependencies

This project requires:

• libfranka installed system-wide (CMake package Franka)
• Eigen3 available to CMake (e.g. /usr/share/eigen3/cmake)

Developer installation

Build and install into your active virtual environment:

• Ensure your venv is active (e.g., . .venv/bin/activate from repo root)
• Initialize submodules, then install:

git submodule update --init --recursive
pip install .

Installing libfranka on Ubuntu 24.04 (recommended)

As said, you must have libfranka installed locally before installing positronic-franka (wheels are not provided).
