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! Sequential Instructions Program to make chocolate milk 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

What is An Intelligent Robot? A machine able to extract information from its environment and use knowledge about its world to move safely in a meaningful manner

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.
