This is a modified version of the turtlebot3_gazebo folder from turtlebot3_simulations. This repository contains a turtlebot3 waffle pi model with an added GPS sensor and an empty world with spherical coordinates.
This repo does not replace turtlebot3_simulations and must be installed alongside it. git clone this repo within the src folder of a ROS 2 workspace and use colcon build.
