🚀 Day 2 - ROS 2 Journey Today's focus was on one of the core communication mechanisms in ROS 2: the Publisher–Subscriber architecture. I developed two ROS 2 nodes: 📤 Node G (Publisher): Periodically publishes integer messages to a topic. 📥 Node H (Subscriber): Subscribes to the same topic, receives each message, and maintains a cumulative running sum by incrementally aggregating the incoming data. This exercise provided hands-on experience with several key ROS 2 concepts: 🔹 Node creation and lifecycle 🔹 Topic-based communication 🔹 Message exchange using std_msgs 🔹 Asynchronous publish–subscribe workflows 🔹 Stateful data processing through cumulative aggregation While the implementation is simple, it reflects the same communication model used in larger robotic systems, where independent nodes exchange information efficiently without being tightly coupled. Every project adds another piece to understanding how distributed robotic applications are built. Looking forward to what's next! 🚀 #ROS2 #ROS2Jazzy #Robotics #PublisherSubscriber #DistributedSystems #DDS #Python #Linux #Automation #RoboticsEngineering #LearningJourney
