ROS and OpenCV can work together for accomplishing incredible tasks. In this tutorial for beginners we are going to use the Rover's camera for detecting and tracking a blue golf ball.

We will develop multiple nodes, each responsible of one particular task:
- capturing and streaming the camera
- detecting the ball
- calculating control actions to track the ball
- controlling the rover to follow the ball

We will be building up on everything we have learned in the previous tutorials: you can find the complete playlist right here: youtube.com/watch?v=N6K2LWG2kRI&list=PLuteWQUGtU9BU0sQIVqRQa24p-pSBCYNv
