opensourceleg 3.5.0

An open-source SDK for developing and testing algorithms on commonly used robotic hardware.

opensourceleg: An open-source SDK for developing and testing algorithms on commonly used robotic hardware. Originally developed for the Open-Source Leg project, this library provides a comprehensive framework for interfacing with various actuators and sensors in robotic systems. While initially designed for prosthetic leg applications, the opensourceleg library's modular architecture makes it versatile for use with any robotic platform utilizing similar components.

Note: Starting from version opensourceleg 3.3.0, only Python 3.11 and above are supported. If you need compatibility with Python 3.9, please install opensourceleg 3.2.1:

pip install opensourceleg==3.2.1

Python 3.10 is not supported.
