Course Curriculum: Weekly Lessons
Week 1: Introduction to ROS2 for Industrial Applications
Title: Laying the Industrial Foundation: ROS2 Overview and Setup
We begin by establishing why ROS2 is the future of industrial robotics. More than just an update to its predecessor, ROS2 was rebuilt from the ground up on top of the Data Distribution Service (DDS) middleware. This provides critical features for industrial settings, including real-time control capabilities, enhanced security, and a decentralized architecture that eliminates single points of failure. This week, we explore the key advantages ROS2 offers over other frameworks, from its configurable Quality of Service (QoS) policies that guarantee message delivery to its support for multi-robot fleets. You’ll set up your development environment and get hands-on with the core building blocks of any ROS2 system: nodes (your processes), topics (your communication channels), and messages (your data).
Hands-on Example: Install ROS2 and create your first workspace. You’ll build and run two simple Python nodes: a talker that publishes a string message and a listener that subscribes to the topic and prints the received message, confirming your environment is fully operational.
Week 2: Deeper Dive into ROS2 Communication: Services and Actions
Title: Orchestrating Industrial Tasks: Services and Actions in ROS2
While topics are perfect for continuous data streams like sensor readings, industrial tasks often require more structured communication. This week, we explore two powerful patterns: services and actions. ROS2 services provide a synchronous, request-response model, ideal for quick, blocking operations like querying a robot’s current configuration or triggering a gripper. When a client calls a service, it waits for a direct response. In contrast, ROS2 actions are designed for long-running, asynchronous tasks that require feedback, such as a multi-stage assembly process or navigating a mobile robot to a destination. Actions allow a client to send a goal, monitor progress via feedback messages, and even cancel the task mid-execution. Understanding when to use each pattern is crucial for designing efficient and responsive industrial systems.
Hands-on Example: You will implement a service where a client sends two numbers to a server, which returns their sum. You will then build an action where a client sends a target countdown number to a server, which provides feedback each second until it reaches zero and returns a final result.
Week 3: Configuring and Launching Complex Industrial Robotics Systems
Title: Building Scalable Systems with Parameters and Launch Files
A real-world industrial robot is not a single program but a complex ecosystem of dozens of interconnected nodes. Managing this complexity is a major challenge. ROS2 parameters solve the problem of hard-coded values, allowing you to externally configure nodes without recompiling your code. This is vital for tuning robot behavior on a factory floor. To manage the entire system, we use ROS2 launch files. These powerful Python or XML scripts allow you to start, stop, and configure multiple nodes at once, define their parameters, and even set up entire robot behaviors with a single command. Mastering launch files is the key to creating deployable, repeatable, and easily manageable robotic applications.
Hands-on Example: You will create a ROS2 package and write a node whose behavior can be changed using a parameter. Then, you will write a Python launch file that starts both your talker and listener nodes from Week 1, using a parameter to set the Hello World message at runtime.
