Autonomous Ground Vehicle Navigation and Control Simulation Examples in Python
THIS PROJECT IS CURRENTLY A WORK IN PROGRESS AND THUS THIS REPOSITORY IS INCOMPLETE
This is a repository of introductory autonomous ground vehicle (i.e., wheeled mobile robot) simulation examples in Python. The purpose of these examples is to provide easy-to-follow code that is illustrative of a number of fundamental mobile robot modelling, control, and navigation (localization, mapping) concepts. Motion planning problems lie beyond the scope of this example set. The focus here is on ground vehicles, although the presented techniques are also applicable more broadly. This code was initially developed to supplement topics covered in the course ELEC 845 Autonomous Vehicle Control & Navigation in the Department of Electrical & Computer Engineering at Queen's University.
MoBotPy Package
The repository also includes a supporting Python package MoBotPy (mobotpy) that contains some code that is used repeatedly. Code developed in the worked examples is subsequently added to MoBotPy.
| Module Filename | Description |
|---|---|
| integration.py | Provides basic Runge-Kutta and Euler integration functions. |
| models.py | Provides standard vehicle models, plotting, and animation methods. |
| graphics.py | Provides some basic shape plotting functions (used by models.py). |
