  1. Group 17: Clinton Bencsik Mark Brosche Christopher Kulinka Christopher Redcay FAMU-FSU College of Engineering Maple seed sensor housing for desert reconnaissance

  2. Overview • Introduction • Project Scope • Design Concept • Proposed Component Diagram • Parts Needed • Power • Prototype Design • Cost Analysis • Conclusion

  3. Project Scope Design a sensor vehicle to house a battlefield awareness network that can be dropped from any altitude.

  4. What is significant about a Maple seed? • Wing on seed is a natural mechanism for dispersing seeds over a large area. • Seeds “float” to the earth using auto-rotating flight Why a Maple seed? • Simplifies design to avoid complex moving parts • Produces a desirable spread pattern to monitor a large area

  5. The Design Concept • Single wing auto-rotating design • Seed sensor housing (1) • SDM manufactured • Integrated sensors and controllers • Integrated circuits • Integrated transmitter and power source • Wing with flexible solar cells (2) • Provides power to batteries • Curve and shape cause auto-rotation in flight • Wing spine (3) • Provides support for the light, thin wing 1 3 2

  6. The Design Concept Video Dramatization. Objects not to scale.

  7. Proposed Component Diagram • Power collected from solar cell. • Energy stored in DC battery. • Simultaneously senses infrared signals and ground vibrations. • Sensor outputs directed to microcontroller. • Signal transmitted to central unit.

  8. Parts Needed a • Sensors • Infrared sensor • Glolab IR module DP-001 • Vibration sensor • SQ-SEN-200 Omni-directional tilt and vibration sensor (a) • Power • Flexible Solar cells (b) • 4.5” x 1.5” (3V at 50 μA) • Batteries • Vibration Sensor • CR-2032 (c) • Microcontroller • Infrared Sensor b c

  9. Power • Vibration Sensor – Signal Quest • Voltage: 3V • Current: 5mA • Power: 0.06W • Flexible Solar Cells – Silicon Solar • Dimensions: 4.5” x 1.5” • Voltage: Provides 3V • Current: 50mA • Power: 0.15W • Infrared Sensor – Glolab • Voltage: 5-20V • Microcontroller • Dimensions: 0.5”x0.8” • Voltage: ????

  10. Application of the Lift Equation to Auto-Rotating Wings

  11. Obtaining the Final Equation • We now combine the approximated lift equation with the simplified area to get lift as a function of length & Note: CI= lift coef. , ρ= air density , ω= angular velocity

  12. Prototype Design

  13. Fused Deposition Modeling Prototype Overall Length – 5.8”, Seed Length – 1.5”, Wing Width – 1.75”

  14. Prototype Video Actual Maple Seed in Flight Prototype Maple Seed in Flight

  15. Cost Analysis • Total Cost Per Seed: $96.405

  16. Conclusion • Exploded View • 1 - Seed Body 2 - Solar Panel (2) 3 - IR Sensor (2) 4 - Vibration Sensor 5 - Battery, Microcontroller
