ROS Project for a Robot to chase a white ball.
Congratulations! Your project meets all of the requirements.
Please, take care and keep on the nice work!
PS. Now that you have passed the project basic requirements, you may want to push your implementation further to make your project stands out. For instance, you could write your process_image node by using a class as illustrated in this link. Also, you could use cv_bridge to explore the possibility of detecting, and chase, a ball of any color using OpenCV. Please refer to link 1 and link 2 for more information.
