  1. Introduction to Artificial Intelligence Jerry B. Weinberg, Associate Professor Department of Computer Science

  2. What is a Computer? • Takes input • Keyboard, mouse, camera, microphones • Transforms it through a set of instructions called a “program” (software) • Central Processing Unit (CPU) • Creates output • Monitor, speakers

  3. What is a Computer? • ALL programs are made up of only 3 kinds of instructions! • Sequential Instructions Program to make chocolate mild First put milk in a glass next add two tablespoons of Nestle Quick stir drink • Conditional Instruction If (you are out of milk) then go to the store and buy a gallon of milk • Repetition While you are still thirsty Make chocolate milk

  4. Artificial Intelligence • Getting computers to do things that humans do • Our Brains are process information like computers • Input: eyes, ears, skin, tongue, nose • Transformation: the brain is our CPU • Output: hands, feet, mouth

  5. Robots are Computers with a Body • A mobile robot is a computer with wheels (or legs or treads or other)

  6. Human Intelligence versus Insect Intelligence • Thinking versus Reacting • People think, insects react

  7. Sensing: Feel

  8. Sensing: sight

  9. Sensing: sight

  10. Meet TazThe Tour Guide Robot

  11. How does Taz figure out where it is? • Has a map in its memory. • Measures how far it travels to get a rough idea of where it is at on the map. • Uses its laser and sonar readings to recognize places on its map to get an exact location
