Division of Labor

Task Team Member

• Processor / Memory / FPGA Jerome Jong

• Drive/Steering & Lift Motors Michael Chin

• Proximity Sensor Joseph Rael

• Software Gabe Anderson

Schedule

Milestone I

• Processor / Memory / FPGA

• Drive / Steering Control (simple)

• Begin Coding

Milestone II

• Complete Drive / Steering (includes working code)

• Lift System (one working motor)

Expo

• Complete Lift System (includes working code)

• Video Camera / Microphone

• Complete Code

• Possible additional Video Controls

Return On Investment

• Market

- FBI / CIA / NSA

- Military

• Cost of Material

- $285 + $100 = $385

• Cost of Labor

- $28.85/hour (x4) = $115.38/hour x 80 hours = $9,232

• Total Cost

- $9,617

• Per Unit Cost

- $12,000

• Expected Sales

- 200 units

• Total Profit

- 200x$12,000 – 200x$9,617 = $476,600

Conclusion• Office Surveillance ROVER

• Chassis Drive, Stepper Motor Lift

• Straight Tether of WebCam/Mic to Remote Terminal

• Sonar Ranging for Sensing Obstacles

• Covert , Unsuspecting, Your Worst Nightmare.
