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!

(or legs or treads or other)
Human Intelligence versus
Insect Intelligence

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
