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! 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

10. Meet Taz The 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
