  2. Competition Scoring

  3. Boat Structure • Frame • Made from fiberglass T-slot bars • Frame may be changed to aluminum hollow square bars • This can save 0.7 lbs per foot • Pontoons • Hollow 100% fiberglass • Drain plugs • Uses aluminum hollow square bars for mounting legs

  4. Propulsion System • Motors • Two Prowler 30 lbfelectric motors • Motor positioning • Shafts are locked in a forward position • Rotation by differential thrusting of motors • Motor Mounting • Mounted at the stern of the boat • Twin frame bars for extra strength • Blade Shields • Built by Norva-Plastics , $250 (half priced for ODU)

  5. Central Processing Unit • Components • Land computer, Internal Computer, GPIO-24, Digital to analog converter, IFI robotics controller, two Speed Controllers, Motors • Speed controllers take a PWM signal • Computer is being defragmented • 12v battery

  6. Waterproofing • All wires are re-routed to the top of the box • Holes on the lower section of the electrical box are all sealed • A splash guard will be placed on top of the existing lid, the new lid will be waterproof • This splash guard will house the cameras

  7. Cart • Dimensions: 8” tall x 5’ long x 3’ wide • Required by competition rules

  8. Logic/VisionIntegration • Vision can now detect all four buoy colors (red, green, blue, yellow) • The center of each buoy is recorded in the picture frame (pixel) • Logic code has be successfully integrated into the bottom of the vision code • Cameras are being temporarily mounted to the electrical box while the waterproof shield is being built

  9. Ghant Chart

  10. Budget • Initial Funds - $3000 • Current Costs • New motor - $100 • Blade shields - $250 • Registration Cost - $500 • Future Costs • Frame upgrade - $200 • New pontoons - $200 • Waterproofing case ~ $350 (TBA) • T-Shirts - $6 each x 14 team members = $84 + tax • Final savings - $1316 (party?)
