Module 1: The Robotic Nervous System (ROS 2)
Focus: Middleware for Robot Control
Welcome to Module 1 of Chapter 2. This module is dedicated to unraveling the intricacies of the Robot Operating System 2 (ROS 2), specifically focusing on its role as the fundamental middleware for controlling and coordinating robot functionalities. In the world of physical AI, effective communication between various hardware components and software algorithms is paramount. ROS 2 provides the standardized framework that makes this possible, enabling a modular, distributed, and highly flexible approach to robotics development.
Here, we will move beyond theoretical understanding to practical application, giving you the tools to design, implement, and manage the communication backbone of your humanoid robot projects. We'll cover the core concepts that allow different parts of your robot to talk to each other, process sensor data, and execute commands in real-time.
Lessons in this Module:
The following lessons will guide you through the essential aspects of ROS 2 middleware:
- Lesson 1: ROS 2 Nodes, Topics, and Services
- Detailing Heading: ROS 2 Architecture and Core Concepts
