Proposal

Camera GrenadeA 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

• 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

• 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.

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
