Self-Ordering Bocce Ball System

1. Self-Ordering Bocce Ball System • Advisor • Dr. Joseph Hoffbeck Authors Michael Chhor Brent Groulik Sean Pfister Allan Young University of Portland School of Engineering

2. Agenda • Introduction Allan • Background Brent • Methods Sean • Results Michael • Conclusions Allan • Demonstration All University of Portland School of Engineering

3. Introduction • Our project - Automatic Ordering • Would reduce downtime during game play Handheld Device Pallino Bocce Ball Actuate Sense Sense Process Process University of Portland School of Engineering

4. Background • Why does order matter in Bocce? • What is a Pallino? • Displaying and updating the order, how? University of Portland School of Engineering

5. System Breakdown Pallino Amp Speaker Oscillator Ckt Bocce Ball Representation Amp Amp BPF Comparator Microphone PIC RF Module Handheld PIC RF Module LCD University of Portland School of Engineering

6. Methods • Acoustic system • Pallino generates and sends 14kHz signal • BBR receives and processes signal • Problems we encountered University of Portland School of Engineering

7. Methods (Cont.) • RF system • BBR sends an RF signal using a PIC and the Xbee RF modules • Handheld receives, processes, and displays the signals. Ball1 Ball2 Ball3 Ball2 Ball3 Ball1 University of Portland School of Engineering

8. Methods (Cont.) • Worked backwards • Handheld – used knowledge from past classes • BBR – research and past group material • Pallino – research University of Portland School of Engineering

9. Results: Our System Ball2 Ball3 Ball1 Field of Play Players University of Portland School of Engineering

10. Results: Building the System Pallino Amp Speaker Oscillator Ckt Bocce Ball Representation Amp Amp BPF Comparator Microphone PIC RF Module Handheld PIC RF Module LCD University of Portland School of Engineering

11. Conclusions • Achievements • Our system works • Players cannot hear the tone emitted from the Pallino • This project will help reduce down time in the game • Our project helps players determine which ball is closest to the Pallino • Improvements • Make the system smaller • Use low power electronics University of Portland School of Engineering

12. Demonstration We will be showing a full demonstration of our project in a video. http://teaching.up.edu/srdesign/AY12/WithoutLimits/photos.htm http://youtu.be/fpyI8smWDyI University of Portland School of Engineering
