Module 1: The Robotic Nervous System (ROS 2)

Introduction​

ROS 2 (Robot Operating System 2) serves as the middleware that connects all components of a robotic system. Think of it as the nervous system of a robot—it enables communication between sensors, actuators, and AI agents.

Learning Objectives​

By the end of this module, you will be able to:

  • Understand ROS 2 architecture and core concepts
  • Create ROS 2 nodes, topics, and services
  • Bridge Python AI agents to ROS 2 controllers using rclpy
  • Work with URDF (Unified Robot Description Format) for humanoid robots
  • Build and deploy ROS 2 packages

Why ROS 2?​

ROS 2 provides:

  • Distributed Architecture: Components can run on different machines
  • Real-time Capabilities: Better performance for time-critical operations
  • Language Support: Python, C++, and other languages
  • Industry Standard: Used by major robotics companies worldwide
  • Open Source: Free and actively maintained
