The Wildlife Tracker project aims to create an innovative tracking device that attaches to arrows to aid bow hunters in monitoring animal locations after shots. By ensuring animals can be tracked even after traveling long distances, this technology seeks to reduce animal deaths and improve hunting efficiency. Key aspects discussed in the design review include engineering requirements, system and subsystem analysis, risk assessment, and a test plan to ensure the device's effectiveness. Stakeholder involvement and deliverables such as a handheld GPS device and user manual are also highlighted as priorities. ### Relevant

Wildlife Tracker: Subsystems Design Review MSD I Team P14347
Agenda • Project Background • Engineering Requirements • System Analysis • Subsystem Analysis • Risk Assessment • Test Plan • Action Items • Questions
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
Previous Action Items • Met with RIT Archery Club • Made contact with EE professors • Dr. Tsouri • Dr. Amuso • Filled in missing engineering requirements values • Narrowed down our solution possibilities • Made contact with Dr. P. Venkataraman
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
Project Deliverables • Re-attachable tracking device that connects onto an arrow • Handheld device that monitors the location of the tracking device • User Manual
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

Bow Efficiency vs Arrow Weight Example B.W. Kooi - “On the Mechanics of the Bow and Arrow”
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
User Device - Electronics • 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) • GPS Receiver • Receive location coordinates of user • Power Consumption : 66mW (at 3.3V) • Small LCD Screen • Displays map, user, 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]
Transmission of Signal GPS Receiver Satellite GPS Receiver LCD Screen Microcontroller Microcontroller RF Receiver RF Transmitter Arrow Attachment User Device
Transmission of Signal • Must meet FCC Regulations • Low frequency waves • Work better around obstacles (e.g. trees) • Goal is to utilize AM frequency range (535-1705kHz) • Transmitter must be low weight, low power consumption • Receiver has more flexibility
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
RF Transmitter/Receiver • LR Series • Small size • Input voltage: 3.0V • Supply current: ~3-15mA • -40 to 85 degree Celsius operation • Transmit/receive RF signals
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
Action Items • Determine if cellphone integration is possible • Look into Google Maps integration • Start designing circuitry • Select a battery (especially for arrow attachment) • Enclosure model • Refine budget • Begin purchasing test parts
