  1. ENGR 50 Robotics Woody Knapp Monterey Peninsula College

  2. air surveillance drone Robots in the News Eldercare robot

  3. Robots at MPC MPC Team competes in National ROV Competition 2013 Team forming soon ENGL 38 More or Less Than Human? Online class studies sci-fi implications of tech ENGR50 Robotics

  4. Rachel, Tom and Ross, MPC ROV Team Members

  5. From Metropolis to The Matrix, this MPC class investigates classic, historical, popular, and contemporary films, TV, and associated literary works which ask, “What is a human being . . . and what isn’t?”  Considerations include representations of utopias and dystopias, computer technologies and networks, artificial intelligence, reproductive technologies, virtual reality, and genetic engineering.  The emphasis will be on how formal qualities affect/effect meaning and interpretation.

  6. 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?]

  7. 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 thumb drive (or DropBox acct) for shuttling programs

  8. Robotics Tool Kit • PC for writing and downloading programs • "Brain" or Microcontroller • (BASIC Stamp, Lego Mindstorms, PIC, Arduino) • 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

  9. 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

  10. 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 Arduino Uno 16 MHz 32 KB 32 KB $30 Lego RCX 16 MHz 1.2K per prog (up to 5) $100 PIC16F84 An excellent source of detailed information: The Robot Builders Bonanza, Gordon McComb (RBB)

  11. 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

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

  13. Lab 0 -- Music Programming • You can hear your program running! • Variables • If statement • For next loops • Explore the structure of music and software

  14. Lab 1 Navigation and Drawing

  15. Lab 3 Navigating with Photo Resistors

  16. Lab 4 Infra Red Detectors

  17. Final Design Project

  18. Along the way you’ll also learn about… 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…

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

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

  21. Today, a brief trip to Mars • We check out kits • Grab a kit • Run Stamp software on PC • Plug in serial cable • Power up bot • Download MarsRover.bs2 program • Modify this line to make bot move in a pattern • data "FFFBBLFFRFFQ"

  22. A Simulated Mars Rover

  23. Mars Sequencing Team (You) • Develop sequences to take Rover to visit a rock (or three) over several Martian days (called “sols”) • Five tries (1 per “Sol”) • 5 points for hitting a rock • -1 point for each Sol • -3 points for rolling off table! • Your Command Sequence is made of Letters: FFrBbRFfLlFLFQ

  24. SequenceKey: • f = 2 inches forward • b = 2 inches backward • l = 20 – 30 degrees left • r = 20 – 30 degress right • F = 10 – 12 inches forward • B = 10 – 12 inches backward • L = 80 – 100 degrees left • R = 80 – 100 degrees right • All measurements are approximate!

  25. The Rules • Table is “Mars” • Measure rock distances • Design your sequence • Test at your work area (Earth) • (no testing on the table!) • Carry bot to “Mars” • Start in the landing zone • Wherever bot stops, place your team’s postit note. Report score to instructor. • Take bot back to earth • Plan next day’s sequence • Resume bot at postit note from last sol • etc

  26. Happy Driving!
