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

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
