ROS imlementation of a simple Robot within a Gazebo simulated office. The robot uses a camera to look for a white ball and navigates towards it.

Contains two ROS packages:

my_robot: Simple robot consisting of 2 rotation wheels and a caster wheel for movement, a Camera and LiDAR sensor for sensing.
ball_chaser: Ball chaser package with 2 nodes implemented in C++:

drive_bot: Service for commanding robot's movement
process_image: Subcribes to raw images, detects if a white ball is withing Field of View and drives the bot accordingly.
