  9. Using Robot kits to develop audio sensors

  10. Telephone Tone Bot Controller By John Jenson

  11. In this class we use a kit from Parallax, Inc. • Build circuits • Write programs • Draw pictures with bots • Respond to whiskers • Respond to light levels • Use IR LEDs in navigation • Maze competition or [other?]

  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

  15. Microcontroller vs. Microprocessor Progrm Space Long term Clock "RAM" Storage Cost PC (Intel Duo) 3 GHz 1GB Hard Drive $350 BASIC Stamp 20MHz 2 KB 2 KB $50 BasicX-24 32 KB 32 KB $50 Lego RCX 16 MHz 1.2K per prog (up to 5) $100 PIC16F84 An excellent source of detailed information: The Robot Builders Bonanza, Second Edition, Gordon McComb (RBB)

  16. Microcontrollers Can Teach You About: • Digital circuits • Use of: resistors, capacitors, LEDs, diodes, transistors • Cook book circuits are readily available (RBB) • Control theory -- feedback, proportional control • Computer architectures • Test & calibration • Software -- compact notation for expressing solutions to problems • Learning by Osmosis

  17. Many Academic Fields Related to Robotics Electrical Engineering Mechanical Engineering Computer Science Motion Planning Perception Sensors Control Mechanisms Mechanics

  18. Music Programming • You can hear your program running! • Variables • If statement • For next loops • Explore the structure of music and software

  19. Navigation and Drawing

  20. Navigating with Photo Resistors

  21. Infra Red Detectors

  22. Final Maze Competition

  23. Light Emitting Diodes • A type of diode designed toemit light • Can be visible or IR • 2 V voltage drop • Typically draws 20 mA (0.020 A) • Schematic Symbol…

  24. How to Read a Circuit Schematic 3 W IT i1 i2 6V 6 W 6 W

  25. How to build Circuits on Breadboard Vin (6 V) Vss (Ground)

  26. Today • We check out kits (one may need a new chip) • Grab a kit • Run Stamp software on PC • Plug in serial cable • Power up bot • Download program 2.5 • Modify this line to make bot move in a pattern • data "FFFBBLFFRFFQ"
