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 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.
