TL;DR

An open-source Python project that collects robotics algorithms for autonomous navigation, with beginner-friendly implementations and visual animations.

ABSTRACT

This paper describes an Open Source Software (OSS) project: PythonRobotics. This is a collection of robotics algorithms implemented in the Python programming language. The focus of the project is on autonomous navigation, and the goal is for beginners in robotics to understand the basic ideas behind each algorithm. In this project, the algorithms which are practical and widely used in both academia and industry are selected. Each sample code is written in Python3 and only depends on some standard modules for readability and ease of use. It includes intuitive animations to understand the behavior of the simulation.

Motivation & Objective

• Introduce an OSS project that compiles practical robotics algorithms in Python
• Enable beginners to understand the core ideas behind each algorithm through readable code

• Include intuitive animations to illustrate algorithm behavior

Proposed method

• Codebase consists of Python3 implementations of robotics algorithms
• Dependencies limited to standard modules for readability and ease of use
• Focus on autonomous navigation algorithms commonly used in practice
• Visualizations/animations accompany the samples to demonstrate behavior
