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
Cradle Design Types
• UU Design– Little more
supportive– Capable of heavier
weights– Larger range of
motion– Tilting motion only
Cradle Design Types
• UU Hover Variation Design– Most complex– Largest range of
motion– Capable of horizontal
and vertical motions (tilt and pan)
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
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
Wireless RF Transmitter
• Includes a transmitter and receiver
• No mess with wires• Quality may not be
great
Pan and Tilt Controls
• PIC will be wired up kite line to power 180O servo and a 360O servo or stepper motor attached to the camera cradle

Conclusion
• Integrated systems of Kite Camera• Funding is a possible problem• Testing and experimentation is vital
