featherstone_py

This project is a Python implementation of rigid body dynamics algorithms, based on Roy Featherstone's book, "Modern Robotics: Mechanics, Planning, and Control", and the MEE5114 course. This project was created primarily for self-education but can also help those who going to enter the field of computational rigid body dynamics and prefer the Python ecosystem over MATLAB/Julia or C++.

The examples in this project can help to clarify the differences in notation between Featherstone's book and the "Modern Robotics" book, which can be quite confusing. Please check out the example models and test cases for more details.Please check out the example models and test cases for more details.
