ROS topics

ROS topics are like a messaging system in robotics, allowing different parts of a robot or system to communicate with each other. Think of a topic as a channel where information is shared; for example, sensor data like camera images or robot commands are published to a specific topic. Other components can subscribe to these topics to receive updates in real time. This setup helps keep the system modular and flexible, as different parts can publish or listen to data independently, enabling efficient and organized communication within complex robotic architectures.
