Presentation Outline • Existing Technology • Design Objectives and Goals • Components for Design • Cost Analysis • Schedule • Conclusions • Questions
Existing Technology • Kite Aerial Photography (KAP) • Began with Hobbyist • Still-Photography • Simple suspension systems
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
Components for Design • Kite • Camera Cradle • Cradle Suspension • Camera • Video Transmission • Pan & Tilt Controls
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
Kite Selection • Parafoil • Steady and easy to control • Inexpensive • Easily assembled • Excellent lift • Winds ranging from 8-25 mph • 17 square feet
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
Cradle Design Types • LL Design • Most simple design • Lightweight • Supports only smaller cameras • Smaller range of motion • Tilting/Rotating motion
Cradle Design Types • UU Design • Little more supportive • Capable of heavier weights • Similar range of motion • Tilting/Rotating motion
Cradle Design Types • UU Hover Variation Design • Most complex • Largest range of motion • Capable of horizontal and vertical rotations as well as tilting
Suspension Types Pendulum Picavet
Pendulum • Made of two rigid tubes • Hard to control camera’s movements • Uncontrollable swinging leads to inaccurate and blurry pictures
Picavet • Contains a self-leveling platform that resists rotation • Suspension line attached various ways • Small cross resists rotation better than a large one
Attaching the Picavet Cross to Line • Ball bearing • Pulleys • Eye holes • Cord locks
Attaching the Suspension to the Kite • Prussik Knot • Line Tree • Brooxes Hangup
Threading the Line Threading SequenceA1 - 1 - B1 - R - 4 - A2 - R - 2 - B2 - 3 - A1.
Cameras • Snap Shot • Takes still images • Blind shots • Smaller • Video • Allows for live streaming video • More expensive
Digital Video Cameras • JVC GR-D70U • 16x optical zoom • Sports mode • Li ion battery • Mustek DV 5500 • Lightweight • Cost effective ($100) • Li ion battery
Video Transmission • Types • Fiber Optic Cable • Wireless RF Transmitter • S-Video Cable
Fiber Optic Transmitter • Includes a transmitter and receiver • Power supply needed for transmitter
Wireless RF Transmitter • Includes a transmitter and receiver • No mess with wires • Quality may not be great
Pan and Tilt Controls • Controlled by PIC (Peripheral Interface Controller) • PIC16F873
Pan and Tilt Controls • PIC will be wired up kite line to power 180O and 360O servo and/or stepper motor attached to the camera cradle
