Wildlife Tracker: Subsystems Design Review

1. Wildlife Tracker: Subsystems Design Review MSD I Team P14347

2. Agenda • Project Background • Engineering Requirements • System Analysis • Subsystem Analysis • Risk Assessment • Test Plan • Questions

3. Team P14347 & Introduction

4. Current & Desired State • Injured animals can travel substantial distances, may be difficult to track • Game which has been shot and cannot be found leads to more animal deaths and inefficient hunting • Wildlife Tracker will detach from arrow and remain attached to animal • Handheld device will provide GPS location of animal

5. Previous Action Items • Met with RIT Archery Club • Made contact with EE professors • Dr. Tsouri • Dr. Amuso • Decided on solid concept • Biggest decision – method of communication

7. Stakeholders • Primary Customer: Dr. Eli Saber • Faculty Guide: Art North • End Users: Bow Hunters • Other: Hunting Stores/Distributors, Game Wardens, Environmental Activists • MSD Team 14347

8. Project Deliverables • Re-attachable tracking device that connects onto an arrow • Handheld device that monitors the location of the tracking device • User Manual

9. Benchmarking • GameVector Deer Recover System • $399.99 • 45 Grains (2.9 grams) • Battery life of 48-72 hours • Up to two mile range • Tested for bows shooting up to 300 feet per second • Currently sold out

20. Bow Efficiency vs Arrow Weight Example B.W. Kooi - “On the Mechanics of the Bow and Arrow”

21. Arrow Attachment - Electronics • GPS Receiver • Receive location coordinates from GPS satellites • Power Consumption : 66mW (at 3.3V) • Microcontroller • Takes data from GPS receiver and converts it to be compatible with RF Transmitter • Power Consumption : 5 mW (at 2.5V) • RF Transmitter • Transmit GPS location from arrow attachment to handheld device • Power Consumption : 9mW (at 3.0V) • Battery • Provide power to Receiver, Transmitter, and Microcontroller • Voltage : 3V

22. User Device - Electronics • Receiver: Radio Frequency • Size Constraints: Mobile (Easy to Handle) • Power Constraints: Mild • User Interface: Straightforward • RF Receiver • Receives GPS data from arrow attachment • Power Consumption : 15mW (at 3.0V) • Small LCD Screen • Displays map and location of animal • Microcontroller • Converts data from RF Receiver to LCD screen • Power Consumption : 5 mW (at 2.5V) • Battery • (4) AA [1.5V*4 = 6V Power Supply]

23. Transmission of Signal Satellite GPS Receiver LCD Screen Microcontroller Microcontroller RF Receiver RF Transmitter Arrow Attachment Handheld Device

24. Transmission of Signal • Must meet FCC Regulations • Low frequency waves • Work better around obstacles (e.g. trees) • Transmitter must be low weight, low power consumption • Receiver has more flexibility

25. GPS Receiver • LOCOSYS GPS MC-1612-2R module • Input voltage: 3.3V • Supply current: ~20mA • -40 to 85 degree Celsius operation • 12.2 x 16 mm

26. RF Transmitter • LR Series • Input voltage: 3.0V • Supply current: ~3mA • -40 to 85 degree Celsius operation • Can transmit at 315MHz, 418MHz, or 433MHz • Can receive data to transmit from microcontroller

27. RF Receiver • LR Series • Input voltage: 3.0V • Supply current: ~5mA • -40 to 70 degree Celsius operation • Compatible with the LR Series transmitters

28. 4.3” TFT LCD Screen • Thin-Film-Transistor Liquid-Crystal Display (TFT LCD) • Input Voltage: 4.0V • Supply Current: 25mA • Operation Temperatures: -20 to 60°C
