 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
             What is a Computer?
•    ALL programs are made up of only 3 kinds of instructions!
    1. Sequential Instructions
           Program to make chocolate mild
               First put milk in a glass
               next add two tablespoons of Nestle Quick
               stir
               drink
    2. Conditional Instruction
           If (you are out of milk)
                then go to the store and buy a gallon of milk
    3. Repetition
           While you are still thirsty
               Make chocolate milk
         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
  Robots are Computers with a Body
• A mobile robot is a computer with wheels
  (or legs or treads or other)
    Human Intelligence
          versus
    Insect Intelligence




• Thinking versus Reacting
  – People think, insects react
Sensing: Feel
Sensing: sight
Sensing: sight
  Meet Taz
The Tour Guide
    Robot
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
