Physical AI & Humanoid Robotics

Welcome to the Physical AI & Humanoid Robotics learning path! This chapter explores the fundamental technologies powering humanoid robots and physical AI systems.

What You'll Learn​

This chapter covers the complete technology stack for building intelligent humanoid robots, from low-level robot control systems to high-level AI reasoning. You'll gain conceptual understanding of each layer and how they integrate to create autonomous humanoid robots.

Modules​

Module 1: The Robotic Nervous System (ROS 2)​

Focus: Middleware for robot control

Learn how ROS 2 serves as the "nervous system" for humanoid robots, coordinating communication between sensors, actuators, and control systems. This foundational module covers:

  • ROS 2 fundamentals and architecture
  • Node communication patterns (topics, services)
  • Python integration with rclpy
  • Robot description with URDF
