Robotics, automation and AI

Robots & the worldBeginner20 minBefore this: What is a robot?

What you’ll learn

The difference between robotics, automation and AI
How they overlap
Why the difference matters

Three different ideas

Idea	Is about	Example without the others
Automation	Doing a task without people, following fixed rules	A factory conveyor that sorts by weight; an automatic door
Robotics	Machines that sense and act physically in the world	A robot arm repeating a programmed weld
Artificial intelligence (AI)	Software that learns patterns from data to make predictions or decisions	A spam filter; a chatbot; a photo-tagging app

The overlaps

        AI
      ┌─────┐
      │  ┌──┼──────┐

         └─────────┘
 ★ = an AI-powered autonomous robot (e.g. a self-driving delivery robot)

Robotics + automation: most factory robots. They act physically and work without people, but follow fixed programs.
AI + automation: software that decides by itself, like fraud detection.
All three: robots that learn or perceive with AI and act autonomously, such as a robot vacuum that recognises objects to avoid, or a warehouse robot that plans its own routes.

Why it matters

People often say “AI” when they mean simple automation, or call any machine a “robot”. Clear words help you judge claims, risks and jobs more fairly.

Example: sorting recycling, three ways

Version	Robotics?	Automation?	AI?
Magnets pull steel cans off a conveyor	No	Yes	No
A robot arm picks items at fixed positions	Yes	Yes	No
A camera + neural network identifies plastics, and a robot arm picks them	Yes	Yes	Yes

Example: the line follower

Your line follower is robotics + automation: it senses and acts with fixed rules. It becomes AI only if it learns its behaviour from data.
