  1. UIdaho U-571 Kurran Kelly – Lead Designer Silas Van Natter – Team Lead Josh Van Patten – Team Budget Manager Brandt Pedrow – Team Liaison and Recorder BrandenBakken – Team Website Manager

  2. Mechanical Targets • Size • Fits in a 72x36x36 in Box • Currently about 35x15x15 • Weight • Must be under 120 pounds • Aiming for 40 pounds • Actions • Drop a Marker • Shoot a projectile 5 feet • Grasp object from below • 3 planes of Thrust • Knock a pipe off pegboard • Positioning • Cameras down and forward • In-line with torpedoes and droppers • Separate battery pod • Compass away from magnetic interference • Features • Easy access to electronics • Watertight enclosure • Even and minimal drag • Dynamically and statically stable • Very configurable • Slightly positive buoyancy • Convenient carrying by two people • Crane hooks • Heat mitigation • Condensation and leak mitigation • External switches

  3. What We Need To Know Now • Mini Computer • Are we going to use one or not? • Hydrophone • What are your ideas for Circuit Boards? • Size and appearance of the hydrophone droppers? • Is there a location that you would want to see us place them?

  4. Current Design

  5. Current Design

  6. Current Design • Frame Sub-Assembly

  7. Current Design • Circuits and Circuit Rack Sub-Assembly

  8. Current Design • Torpedoes, Cameras, & Marker Droppers Sub-Assembly

  9. Components • The slides under “Components” are showing what we know we must mount to the circuit rack inside the circuit tube. Motherboard and Hard Drive Power Supply Board

  10. Components Cont’d WSU/Digilent Board Depth Sensor, Compass, Gyroscope, Accelerometer Sabertooth Motor Controllers (x3)

  11. Components Cont’d Pneumatic Solenoids and Manifold CO2 Canister and Regulator

  12. Connectors

  13. Battery Box • Box cartridge design with internal sealing • Hot swappable • No need to open for battery changing or charging • Stackable

  14. Battery Box

  15. Senior Lab Experiment • Old vs. New Thrusters • Voltage Supplied vs. Force Created • Forward and Reverse Operation • Analyzing for Statistically Significant Differences between Forward and Reverse Thrust and Old vs. New Thrusters

  16. Senior Lab Results Plot With Outliers

  17. Senior Lab Results Plot Without Outliers

  18. Milestones • Project Learning / Research / Background • End of September • Designing / Prototyping • End of November • Order & Delivery of Parts • Middle of January • Construction of Mark 1 Sub • Middle of February • Mark 1 Design Evaluation • End of February • Mark 1 Testing • End of March • Time for Re-Design • Middle of April • Deliver Re-Design • Middle of April • Portfolio and Logbooks • End of April

  19. Expected Expenditures • Acrylic Tubing and Sheet • Already have 3/8” and ½” sheet purchased • Several Electrical Underwater Connectors • More Bosch Extruded Stock and Connectors • For assembling the frame • Plate Aluminum • For machining the bulkheads and circuit rack • O-Rings • For external housings and bulkhead seals • New Marker Droppers • Also the ball bearings will be re-done • Pneumatics • System will get upgrades or full re-design • Ready Rod (All-Thread) and Assorted Fasteners

  20. What We Need To Know Now • Mini Computer • Are we going to use one or not? • Hydrophone • What are your ideas for Circuit Boards? • Size and appearance of the hydrophone droppers? • Is there a location that you would want to see us place them?

  21. Questions For You • Is there a certain location that you see specific circuits needing to be placed? • On the circuit rack for your ease of use • Out of our Mechanical Targets: • Are there any more that you see us needing to account for? • Do you have an accurate file for the Marker Droppers

  22. Any Questions For Us?
