ROS Package Name: ardrone_color_tracking

Package Description:
    This package enables the drone to follow an object of certain color.
    OpenCV is used to perform image processing, and basic control theory is applied to realize the auto-tracking.
    Video demonstration of the drone and detailed documentation of the code will be added soon.

How to use:
Prerequisite: ROS Kinetic
http://wiki.ros.org/kinetic
    1. With a real drone (Parrot AR.drone):
        a) Install ardrone_autonomy package
            http://wiki.ros.org/ardrone_autonomy
        b) Install this package
            Clone this repository to your catkin workspace/src
            In your catkin workspace, use command catkin_make
        c) To launch, connect your wifi to your Ardrone, and use following launch command in your terminal:
            roslaunch ardrone_color_tracking keyboard_controller.launch

    2. With Gazebo simulation:
        a) Install modified tum_simulator
            https://github.com/hugagaga/4901
        b) launch roscore and the simulator in different terminals
            roscore
            roslaunch cvg_sim_gazebo ardrone_testword.launch
        c) In another terminal, run keyboard_controller.py
            rosrun ardrone_color_tracking keyboard_controller.py

Update:
Mar/19/2019 Color-Tracking works well in simulation.

This package is an extension of ardrone_tutorial package (https://github.com/mikehamer/ardrone_tutorials).
The ardrone_tutorial package provided a frame work for keyboard control and GUI of the drone.
