The Physical AI Development Spectrum
Three distinct levels of robotics intelligence. This textbook focuses on Level 2 & 3, where AI becomes a co-creator and core system component.
Level 1: Teleoperation & Scripts
What it is: Manual control or hardcoded behaviors
- ✓ Joystick teleoperation
- ✓ Pre-programmed sequences
- ✓ If-then logic
Your role: You control everything manually
Impact: Baseline capabilities
Level 2: AI-Assisted Robotics
What it is: AI as your development and runtime partner
- ✓ Spec-driven robot design
- ✓ AI generates ROS 2 code
- ✓ Computer vision for perception
- ✓ Path planning algorithms
Your role: Architect systems; AI implements; you validate
Impact: 5-10x faster development
Level 3: Embodied Intelligence
What it is: AI reasoning as the robot's core capability
- ✓ Natural language commands
- ✓ Autonomous task planning
- ✓ Learning from interaction
- ✓ Multi-agent coordination
Your role: Design agent architectures and guardrails
Impact: New capabilities impossible before

Traditional Robotics vs AI-Native Robotics
| Aspect | Traditional Robotics | AI-Native Robotics |
|---|---|---|
| Development | ❌ Write every line of code manually | ✅ Write specifications, AI generates implementation |
| Control | ❌ Hardcoded behaviors and state machines | ✅ Learned policies and adaptive behaviors |
| Perception | ❌ Hand-engineered feature extraction | ✅ Deep learning for vision and sensor fusion |
| Planning | ❌ Pre-computed paths and trajectories | ✅ Real-time replanning with world models |
| Adaptation | ❌ Fails in novel situations | ✅ Generalizes to new environments |
| Debugging | ❌ Step through thousands of lines | ✅ Refine specifications and constraints |
| Speed | ❌ Weeks to implement new behaviors | ✅ Days with 5-10x faster iteration |
| Scalability | ❌ Each robot requires custom code | ✅ Transfer learning across platforms |
