  Pomeroy, Jeries shihadeh

2
Overview

• Proposal
• Hardware Block Diagram
• Hardware Implementation
• Software Block Diagram
• Software Implementation
• Feasibility and Sustainability
• Safety and Compliance
• Schedule and Division of Labor
• Budget

3
Proposal

• Camera Grenade
• A thrown camera
• Receiver station to capture images
• Present it in an interactive 3D view.

4
Proposal

• Target size (grenade unit) golf ball to softball
• Receiver/Display
• self contained display device
• or possibly a receiver attached via USB to a
  laptop (with associated display software)

5
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

6
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

7
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

8
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)

9
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
11
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?

12
SubSystem Implementations

• Control Unit(s)
• uProcessor MSP430 or CC430?
• External Transceiver nRF24L01 vs. CC1101

13
SubSystem Implementations

• CC1101
• Low sleep current (200 nA)
• Higher Tx output power
• Better attenuation over distance

• nRF24L01
• Higher on-air data rate (2Mbps)
• Lower transmit power

User Perspective.
16
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.

17
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

18
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

19
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

20
Safety and Compliance

• Complies to necessary FCC Military and Civilian
  conventions, depending on model
• Internal Camera Unit Voltages lt 15V

21
Schedule
22
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

23
