Expo Deliverables
• Camera
• 640x480 resolution
• 1 frame per second
• Usable Pictures
• Data Storage
• Store image data on external device (SD card?)
• Image Display
• Proper location and orientation
• “Step-Through” mode
Expo Deliverables
• Packaging
• Contains all components
• Severe impact is not a goal
• Demonstration
• Device can take pictures
• Display images in a proper orientation
• Device is moving at low velocity and acceleration
Higher Deliverables-Phase 1
• Camera
• Captures RGB images
• Greater than 1 frame per second
• 2 cameras
• Depends on budget
• Data Transmission
• RF transmission to base station
Higher Deliverables-Phase 2
• Packaging
• More robust to account for impact
• Demonstration
• Throw ball
• Use of accelerometers to return (x,y,z) position
• More Cameras (Up to 6)
Higher Deliverables-Phase 3
• Camera
• IR capabilities
•
•
•
•
GPS unit
Ball movement after landing
In flight gyroscopic stabilization
Multi-Unit Mapping
• Use GPS with Multiple Camera Units to create a more
comprehensive 3D environment
Block Diagram-Hardware
SubSystem Implementations
• Camera Unit Options
• Number and Layout
• 1 - 6 Standard Cameras
• Two 180◦ Panoramic
Cameras
• Data Throughput
• 8-bit Gray Scale vs. RGB
Color
• Resolution (640x480)
• Possible Secondary IR
Camera?
SubSystem Implementations
• Control Unit(s)
• uProcessor – MSP430 or
CC430?
• External Transceiver –
nRF24L01+ vs. CC1101
SubSystem Implementations
• nRF24L01+
• Higher on-air data rate
(2Mbps)
• Lower transmit power
• CC1101
• Low sleep current (200 nA)
• Higher Tx output power
• Better attenuation over
distance

User Perspective.
Feasibility
• Economics
• Less than $1000 (less than 2x the cost of a standard grenade)
• Most parts are off the shelf and offered by multiple vendors,
with the possible exception of the casing
• Marketability: Military and police usage, data collection
• Possible applications in scientific mapping and observation.
Feasibility
• Risks
• Camera Functionality:
• Is quality of 640x480 resolution good enough?
• Number of frames per second?
• Expense of Camera/Lenses
• Size of Images:
• Considerable amount of data throughput
• Minimize via color constraints, on chip jpeg compression
• Test and Pick Camera ASAP
Feasibility
• Risks
• PCB layout mistakes:
• Team reviews layout before ordering board
• Enough time and budget is set aside for multiple boards
• Knowledge of Packaging:
• Packaging doesn't perform as well as hoped
• Limited knowledge of mechanical design
• Test packaging with dummy contents before full prototype build
Sustainability
• In general, most system parts are available from
multiple vendors
• caveat: although one particular camera may not be available, other
comparable models are.
• Minimal maintenance/support necessary out of box
Safety and Compliance
• Complies to necessary FCC Military and Civilian
conventions, depending on model
• Internal Camera Unit Voltages < 15V
Schedule
Schedule
• CDR
• Able to take and store images
• Milestone 1
• Use accelerometer to determine orientation
• Use software to display image(s) with correct orientation
• Develop power system to power device
• Milestone 2
• Packaging complete
• Expo deliverable in final testing
Division of Labor
• Based on Background Experience
