This repository extends upon the limited functionalities and support of the older version of parrot ardrone repository that could be found here. This version and older versions suffered a discontinuity when ROS melodic was launched since it uses Gazebo 9 in which some dependencies and libraries were deprecated and replaced with others. One recurrent example was the depreciation of Gazebo math.hh library.
That being said, I updated all the .cpp files that depended on Gazebo math.hh to be using Ignition math instead. Also, since this repo was originally built upon Gazebo 7 I had to update the scripts and .cpp filet to the new Gazebo API currently supported by ROS Melodic and Gazebo 9.
