2. Presentation Outline Existing Technology Design Objectives and Goals Components for Design Cost Analysis Schedule Conclusions Questions

3. Existing Technology Kite Aerial Photography (KAP) –Began with Hobbyist –Still-Photography –Simple suspension systems

4. Design Objectives and Goals Design a controllable aerial photography system to accurately capture pictures and video –construct suspension and cradle system –maximize range of motion with motors/electronics Live streaming video

5. Components for Design Kite Camera Cradle Cradle Suspension Camera Video Transmission Pan & Tilt Controls

6. Kites Winged-Box –Stable in heavy winds due to it’s boxed frame –Flies in light winds due to its’ winged design Rokkaku –Solidly built –Adjustable tensioning –Winds ranging from 4-8 mph

7. Kite Selection Parafoil –Steady and easy to control –Inexpensive –Easily assembled –Excellent lift –Winds ranging from 8-25 mph –17 square feet

8. Cradle System Cradle design crucial for maximum camera control Goal to obtain pan and tilt motions Critical Design Characteristics –Center of Gravity –Range of Motion –Support Type

9. Cradle Design Types LL Design –Most simple design –Lightweight –Supports only smaller cameras –Smaller range of motion –Tilting/Rotating motion

10. Cradle Design Types UU Design –Little more supportive –Capable of heavier weights –Similar range of motion –Tilting/Rotating motion

11. Cradle Design Types UU Hover Variation Design –Most complex –Largest range of motion –Capable of horizontal and vertical rotations as well as tilting

12. Cradle System Designs

13. Suspension Types Pendulum Picavet

14. Pendulum Made of two rigid tubes Hard to control camera’s movements Uncontrollable swinging leads to inaccurate and blurry pictures

15. Picavet Contains a self-leveling platform that resists rotation Suspension line attached various ways Small cross resists rotation better than a large one

16. Attaching the Picavet Cross to Line Ball bearing Pulleys Eye holes Cord locks

17. Attaching the Suspension to the Kite Prussik Knot Line Tree Brooxes Hangup

18. Threading the Line Threading Sequence A1 - 1 - B1 - R - 4 - A2 - R - 2 - B2 - 3 - A1.

19. Cameras Snap Shot –Takes still images –Blind shots –Smaller Video –Allows for live streaming video –More expensive

20. Digital Video Cameras JVC GR-D70U –16x optical zoom –Sports mode –Li ion battery Mustek DV 5500 –Lightweight –Cost effective ($100) –Li ion battery

21. Video Transmission Types –Fiber Optic Cable –Wireless RF Transmitter –S-Video Cable

22. Fiber Optic Transmitter Includes a transmitter and receiver Power supply needed for transmitter

23. Wireless RF Transmitter Includes a transmitter and receiver No mess with wires Quality may not be great

24. Pan and Tilt Controls Controlled by PIC (Peripheral Interface Controller) –PIC16F873

25. Pan and Tilt Controls PIC will be wired up kite line to power 180 O and 360 O servo and/or stepper motor attached to the camera cradle
