12. NO PURCHASE NECESSARY But if you want: (optional) Parallax Boe-Bot Full Kit, cost $149 Group discount rates may be available—let me know if you plan to buy one Order online: http://www.parallaxinc.com/ Or call: 1-888-512-1024 You do need: A single 3.5" floppy disk (or thumb drive) for shuttling programs

13. Robotics Tool Kit PC for writing and downloading programs "Brain" or Microcontroller (BASIC Stamp, BasicX-24, Lego mindstorms RCX, PIC16F84) Programming interface (serial cable, infrared (LEGO), wireless) "Skeleton" or chassis, arms "Muscles" or wheels, motors, relays Energy source—batteries Sensors: Speaker, Bumper switch, Photoresistor, Infrared headlights

14. What's a Microcontroller? An ultra minimal computer chip that normally performs a single set of tasks in an embedded system (automatic doors, airplane avionics) Unlike PCs, microcontrollers have special ports to enable simple interfaces with the outside world (input/output) For every PC there are 12-18 microcontrollers in the world
