This guide has been tested using [this ROS environment](https://github.com/ambitious-octopus/rosbot_ros/tree/noetic), which is a fork of the [ROSbot ROS repository](https://github.com/husarion/rosbot_ros). This environment includes the Ultralytics YOLO package, a Docker container for easy setup, comprehensive ROS packages, and Gazebo worlds for rapid testing. It is designed to work with the [Husarion ROSbot 2 PRO](https://husarion.com/manuals/rosbot/). The code examples provided will work in any ROS Noetic/Melodic environment, including both simulation and real-world.

The `sensor_msgs/Image` [message type](https://docs.ros.org/en/api/sensor_msgs/html/msg/Image.html) is commonly used in ROS for representing image data. It contains fields for encoding, height, width, and pixel data, making it suitable for transmitting images captured by cameras or other sensors. Image messages are widely used in robotic applications for tasks such as visual perception, object detection, and navigation.

The `sensor_msgs/PointCloud2` [message type](https://docs.ros.org/en/api/sensor_msgs/html/msg/PointCloud2.html) is a data structure used in ROS to represent 3D point cloud data. This message type is integral to robotic applications, enabling tasks such as 3D mapping, object recognition, and localization.
