What is gzmaze?

gzmaze is an attempt at flexing the power of Gazebo The main goal here is to generate a maze in gazebo from a text file.

How it works

There are two components, a GUI overlay plugin and a world plugin.

GUI overlay

Gazebo has a tutorial on simple GUI overlays. I followed that tutorial, and extended it slightly. There are two buttons and a textedit. When the buttons are clicked, a message is published to the topic ~/maze/regenerate

World plugin

This is where the meat of the code is. We subscribe to ~/maze/regenerate and build mazes using gazebo messages. This plugin took example from the gazebo Model editor. Essentially, it uses gazebo messages to construct Collision and Links. There links are then converted to and sdf::ElementPtr via the convenient funtions VisualToSDF and CollisionToSDF.


This code user to work with gazebo9, and but I've recently tested it with gazebo 11

cmake 2.8 Gazebo

To get the dependencies, you can probably just install from apt


mkdir build
cd build
cmake .. && make


Be sure to add the following to your .gazebo/gui.ini file

source #this will setup the environment variables you need and run gazebo
gazebo --verbose

The input files
