Autonomous vehicle (AV) software stacks are complex beasts, often entangled with heavy machine learning frameworks and opaque components. For anyone starting out or wanting to understand the nuts and bolts of AV control, this Python repository breaks down the classical algorithms into clear, runnable simulations. It’s a practical textbook where each algorithm—from Extended Kalman Filter localization to RRT* path planning and Model Predictive Path Integral control—is implemented from scratch using just NumPy, SciPy, and Matplotlib.
comprehensive classical autonomous vehicle algorithm simulations in pure Python
This repository covers the full spectrum of autonomous vehicle control algorithms, organized into standalone Python scripts. The key domains include localization, mapping, path planning, path tracking, and perception. For localization, it implements Extended Kalman Filter (EKF), Unscented Kalman Filter (UKF), and Particle Filter methods. Mapping approaches include occupancy grids, Normal Distributions Transform (NDT), and potential fields. Planning algorithms span graph search techniques like A*, D*, sampling-based methods like Rapidly-exploring Random Trees (RRT) and its variants, Probabilistic Roadmaps (PRM), Particle Swarm Optimization (PSO), and Elastic Band smoothing.
Path tracking controllers such as Pure Pursuit, Linear Quadratic Regulator (LQR), Stanley controller, and Model Predictive Path Integral (MPPI) are implemented to close the loop. The entire stack is built with a focus on clarity and inspectability, avoiding heavy frameworks like TensorFlow or PyTorch. Instead, it relies on a lightweight scientific Python stack: NumPy for numerical operations, SciPy for scientific algorithms, and Matplotlib for visualization. This choice keeps the code accessible and easy to follow, making it suitable for educational purposes.
The codebase is neatly organized under src/simulations/ with subdirectories corresponding to each domain, such as localization/, mapping/, path_planning/, and path_tracking/. Each simulation is a self-contained Python script that can be executed independently, producing visual outputs that illustrate algorithm behavior and performance.
transparency and educational focus as technical strengths
What sets this repo apart is its emphasis on implementing algorithms from scratch in pure Python, making every step visible and modifiable. Unlike many AV projects that intertwine complex dependencies and opaque ML models, this guide prioritizes code clarity and educational value. The simulations are designed not for production deployment but for understanding the mechanics and tradeoffs of each algorithm.
The tradeoff here is the performance and scalability: pure Python implementations with Matplotlib visualizations are not suited for real-time control in a real vehicle. However, as a learning tool, this approach is invaluable. It allows developers to see under the hood, tweak parameters, and experiment without wrestling with heavy frameworks or opaque binaries.
Code quality appears solid, with pytest-based unit tests covering the core algorithmic components to ensure correctness and robustness. The inclusion of these tests also encourages safe experimentation and extension. The use of Docker Dev Containers for environment setup further improves developer experience, making it easier to get started without dependency conflicts.
The repository also includes design documents that explain the theory behind the algorithms and their implementations, enhancing the self-study potential.
quick start with docker and running simulations
The repository provides clear instructions to set up and run the simulations, especially leveraging Docker for a consistent environment. Here’s the exact quick start sequence from the README:
# Clone the repository
$ git clone https://github.com/ShisatoYano/AutonomousVehicleControlBeginnersGuide
# For development, set up with Docker on WSL:
# - Install Docker beforehand
# - Open the repo folder in VSCode
# - Create Dev Container (automatically installs required libraries)
# Run unit tests to verify environment
$ . run_test_suites.sh
# Run a specific simulation, e.g., Extended Kalman Filter localization
$ python src/simulations/localization/extended_kalman_filter_localization/extended_kalman_filter_localization.py
This workflow minimizes friction and allows you to jump directly into experimenting with algorithms visually. Each script outputs Matplotlib plots illustrating the step-by-step behavior of the algorithm.
who should use this repo and what to expect
This repository is a solid resource for students, researchers, and engineers new to autonomous vehicle control algorithms. It’s especially useful for those who want to get hands-on experience without the overhead of heavy dependencies or production complexities.
That said, it is not a turnkey solution for production AV systems. The implementations prioritize transparency and simplicity over speed and scalability. Real-world AV projects will require more robust sensor integration, real-time constraints, fault tolerance, and extensive validation.
If your goal is to understand the classical building blocks of AV software stacks, explore algorithm behaviors, or prototype ideas quickly in Python, this repo is worth bookmarking. The clear separation of concerns, accompanied by visualizations and unit tests, helps build intuition and confidence before moving to more complex or optimized frameworks.
In summary, AutonomousVehicleControlBeginnersGuide offers a rare, practical deep dive into classical AV control algorithms with readable, runnable code. It’s a textbook come to life — not to replace production code, but to illuminate the path there.
