  1. Ed-Co Vision: To produce a product which is both fun and useful To rule the world Members: Scott Ferrell – Sensors and Communications Jeremy Griffin – MCU and GUI Aric Kalynchuk – Software Development and Research Daisuke Kubo – Power and MCU Chad Shaffer – Communications Brent Thompson – Sensors and MCU

  2. Overview • System Concept and Components • Background and Market Research • System Descriptions • Control • Radio Frequency (RF) Direction Finding • Communications and Graphical User Interface • Cost and Schedule • Project Future

  3. System Components • Extremely mobile user interface • Personal digital assistant • Nintendo Game Boy • Radio Frequency Beacon • Mobile RF signal generator • Small autonomous car • Modified remote controlled car with a microcontroller unit and sensors

  4. System Concept • A mobile controller transmits drive parameters to vehicle • The mobile controller receives sensed data from vehicle • Two modes of vehicle operation • Vehicle can track a RF beacon • Vehicle can follow waypoints

  5. Mode Concepts and Reasons • Track • Will locate and follow a RF beacon • To show all of our skills • Point to Point • For vehicle testing • Allows for future scalability

  6. Market Research Competing Technology • Remote car and sensor platforms being researched from MIT to high school students • Most projects do not provide tracking/sensing technology that is integrable or upgradeable with current market technology Computer controlled sensor platforms. → ←Computer controlled racing, based on pre-programmable behavior.

  7. Market Research Largest Markets • Safety • “after an accident, the violations that frequently top the list are failures to keep pathways clear, floors clean, and emergency exits freely accessible” • Jan Schut, www.plasticstechnology.com • Scientific Research • The Hawaiian Volcano Observatory (H.V.O.) is a good example of an organization that regularly monitors and studies volcanic activity • Entertainment • Sam’s Club is selling twenty-four different types of RC monster trucks this holiday season…Smart Track is the natural integration of technology that Sharper Image and Radio Shack customers already use and are willing to buy

  8. System Overview • RF beacon • Vehicle • RF receiver • Vehicle controls • Wireless comm. • Base station • Graphical user interface (GUI)

  9. Horn antenna gain pattern consists of a single beam with minimal sidelobes Allows for a very simple RF direction finding algorithm Measure received power from both antennas Turn in direction of antenna with greater received power RF Direction Finding Horn 1 RF Beacon Horn 2

  10. Vehicle Speed Control Speed Demand • Determined based on the distance to the beacon Motor Speed • Controlled by switching the motor supply “on” and “off” very quickly • Responds only to the average effect • Longer “on” – speed increase • Longer “off” – speed decrease

  11. Vehicle Direction Control Turn Demand • Determined based on position with respect to the beacon Turning Control • Two servo motors on the front wheels control the direction • Pulse width modulation (PWM) determines the angle of rotation of the motor • Longer pulse – motor turns more • Shorter pulse – motor turns less

  12. Vehicle Microcontroller Unit • ATmega32 MCU • I/O • 32 programmable I/O lines • Operating voltage • 4.5 V ~ 5.5 V • Speed grades • 0-16 MHz • Power consumption at 1 MHz, 3V, 25ºC • Active mode: 1.1 mA • Idle mode: 0.35 mA • Power-down mode: <1μA

  13. Choice of Communication • Bluetooth: powerful but expensive, complex, and power-hungry • Zigbee: developed for industrial applications… not present in consumer devices • Wireless fidelity (WiFi): integrated into PDA’s Game Boy, and many handheld platforms

  14. Extremely Mobile User Interface • Has a very short setup time • Easy to pack away • Familiar technology to consumers • Able to operate while client is in motion • Possible languages and operating systems being considered are (Visual) C++, PalmOS, Java/Flash

  15. Extremely Mobile User Interface

  16. Project Schedule

  17. Project Schedule • First half of winter quarter: Building components • Second half of winter quarter: Integration/programming/debugging • Everyone works in all areas, but responsibility focused for concurrent work

  18. System Components and Pricing Item Cost ATmega32 MCU $10 Lantronix WiPort $120 WiPort antenna $10 RC monster truck $30* Laser distance finder $30* RF antennas ** Wiring, components $40* Cost per system $240 Budget *estimated **own/borrow

  19. Development Components and Pricing Item Cost STK500 DevKit $80 WiPort DevKit $300 Laptop ** Beacon antenna ** Signal generator ** Tools $50*, ** Administrative $150* Cost to develop $580 Budget *estimated **own/borrow

  20. System Futures • The beacon tracking mode • Hunter-seeker applications • The waypoint mode (greatest potential) • Games • Data sensing in hazardous areas • Security patrols
