  • Existing TechnologyKite Aerial Photography (KAP)

    Began with HobbyistStill-PhotographySimple suspension systems

  • Design Objectives and GoalsDesign a controllable aerial photography system to accurately capture pictures and videoconstruct suspension and cradle system maximize range of motion with motors/electronicsLive streaming video

  • Components for DesignKiteCamera CradleCradle SuspensionCameraVideo TransmissionPan & Tilt Controls

  • KitesWinged-BoxStable in heavy winds due to its boxed frameFlies in light winds due to its winged designRokkakuSolidly builtAdjustable tensioningWinds ranging from 4-8 mph

  • Kite SelectionParafoilSteady and easy to controlInexpensiveEasily assembledExcellent liftWinds ranging from 8-25 mph17 square feet

  • Cradle SystemCradle design crucial for maximum camera controlGoal to obtain pan and tilt motionsCritical Design CharacteristicsCenter of GravityRange of MotionSupport Type

  • Cradle Design TypesLL DesignMost simple designLightweightSupports only smaller camerasSmaller range of motion

  • Cradle Design TypesUU DesignLittle more supportiveCapable of heavier weightsLarger range of motionTilting motion only

  • Cradle Design TypesUU Hover Variation DesignMost complexLargest range of motionCapable of horizontal and vertical motions (tilt and pan)

  • Cradle System Designs

  • Suspension Types Pendulum Picavet

  • PendulumMade of two rigid tubesHard to control cameras movementsUncontrollable swinging leads to inaccurate and blurry pictures

  • PicavetContains a self-leveling platform that resists rotationSuspension line attached various waysSmall cross resists rotation better than a large one

  • Attaching the Picavet SuspensionBall bearing

    Pulleys

    Eye holesCord locks

  • Attaching the Suspension to the KitePrussik Knot

    Line Tree Brooxes Hangup

  • Threading the LineThreading Sequence A1 - 1 - B1 - R - 4 - A2 - R - 2 - B2 - 3 - A1.

  • Video TransmissionTypes

    Fiber Optic Cable

    Wireless RF Transmitter

    S-Video Cable

  • Fiber Optic TransmitterIncludes a transmitter and receiverPower supply needed for transmitter

  • Wireless RF TransmitterIncludes a transmitter and receiverNo mess with wiresQuality may not be great

  • Pan and Tilt ControlsControlled by PIC (Peripheral Interface Controller)PIC16F873

  • Pan and Tilt ControlsPIC will be wired up kite line to power 180O servo and a 360O servo or stepper motor attached to the camera cradle
