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

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

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)

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

SubSystem Implementations Camera Unit Options Number and Layout 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 CC1101 Low sleep current (200 nA) Higher Tx output power Better attenuation over distance nRF24L01+ Higher on-air data rate (2Mbps) Lower transmit power

SubSystem Implementations Graphical Environment Google Maps API? Custom designed OpenGL environment? Images manually loaded to OpenGL environment Skybox Net. 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
