Project Description

Overview

This software finds the shortest paths between configurations for the Dubins’ car [Dubins51], the forward only car-like vehicle with a constrained turning radius. A good description of the equations and basic strategies for doing this are described in section 15.3.1 “Dubins Curves” of the book “Planning Algorithms” [LaValle06].

The approach used to find paths is based on the algebraic solutions published in [Shkel01]. However, rather than using angular symmetries to improve performance, the simpler approach to test all possible solutions is used here.

This code is primarily a Cython wrapper of https://github.com/AndrewWalker/Dubins-Curves

Installing

You can install the latest stable version from PyPI

$ pip install dubins

Or, you can install the latest development version from GitHub

$ pip install git+git://github.com/AndrewWalker/pydubins.git

Example

Sampling of a Dubin’s path at finite size sizes

import dubins

q0 = (x0, y0, theta0)
q1 = (x1, y1, theta1)
turning_radius = 1.0
step_size = 0.5

qs, _ = dubins.path_sample(q0, q1, turning_radius, step_size)
