  1. ARTEMISAdvanced Rover Technology forExploration on theMoon using InSitu utilization Jesse Hecht Sean Fierman Cedrick Ngalande

  2. Storyboard → ↑ ↓ ↓ + USC 2004 AME 557 Space Exploration Architecture

  3. Assumptions • Lands remotely, un pressurized • The motors we chose exist or can be built • EVA / entrance / exit and navigation issues are not our problems USC 2004 AME 557 Space Exploration Architecture

  4. Approach USC 2004 AME 557 Space Exploration Architecture

  5. Rover Design • Total Size 14 x 6 x 6 ft (4.3 x 1.8 x 1.8 m) • 4 ft diameter wheels (1.2m) • Living space, pressurized volume 6.5 x 6 x 6 ft (234ft^3, 6.48m^3) • Chrysler Minivan is roughly 161ft^3 interior • Low Center of Gravity • Ground clearance – 2.5 ft (0.76m) • Break over angle – 31 degrees • Door area with 3 access points, 2 ladders • Arm • Lights by cameras for night vision • Weight – 1 ton – less than requirement USC 2004 AME 557 Space Exploration Architecture

  6. Speed • 1 mph needs 3 hp • 25 mph needs 75 hp • Engine per wheel (instantaneous, no gears, high estimate) USC 2004 AME 557 Space Exploration Architecture

  7. Power • Solar Panels USC 2004 AME 557 Space Exploration Architecture

  8. Power • Fuel Cells • Space Shuttle 14kW, 66ft^3 (0.155m^3), 200lbs (91kg) + 100lbs (50kg) of oxygen and hydrogen per day (cryogenic) operates for 2600 hours • ARTEMIS – 7kW, 33ft^3, 100lbs + MgH2 and oxygen weight USC 2004 AME 557 Space Exploration Architecture

  9. SPECIALS • Dust • Wheel design • Regolith shielding (radiation) • 2 inch Al + 1.5 feet of regolith + fuel cell materials • Piloting with no windows! • LCD screens with picture in picture (PIP) USC 2004 AME 557 Space Exploration Architecture

  10. Lunar Wheels USC 2004 AME 557 Space Exploration Architecture

  11. Apollo Rover • Outer & inner frame • Wire mesh • Titanium USC 2004 AME 557 Space Exploration Architecture

  12. Rooster Tails • Push dirt outward NOT Upward USC 2004 AME 557 Space Exploration Architecture

  13. Turbine or Impeller Channels • Used to move all types of materials USC 2004 AME 557 Space Exploration Architecture

  14. Channels – Remove Dirt USC 2004 AME 557 Space Exploration Architecture

  15. Wheel Cross-Sections USC 2004 AME 557 Space Exploration Architecture

  16. Gravity, Centrifugal Force & Blades USC 2004 AME 557 Space Exploration Architecture

  17. No More Upward Rooster Tails • Main Interface with Lunar surface = Wheels • Minimize dirt uplift from wheels USC 2004 AME 557 Space Exploration Architecture

  18. Radiation USC 2004 AME 557 Space Exploration Architecture

  19. Radiation • Rover shell is 2” of aluminum • Partial In-Situ shield (1ft – 1.5 ft thickness) • Flexible bladders (Internal & External) • Fuel Cells USC 2004 AME 557 Space Exploration Architecture

  20. Dose USC 2004 AME 557 Space Exploration Architecture

  21. Problems • Coronal Mass Ejection • Majority is protons • Fequency varies with sunspot cycle • Solar min = 1 CME week • Solar Max = 2 to 3 PER DAY!!!!!!!!!! • 1012 kg @ 1000 km/s USC 2004 AME 557 Space Exploration Architecture

  22. EVA • Pressurized and un pressurized sections • Entrance / exit built into structure • Ladders for side access USC 2004 AME 557 Space Exploration Architecture

  23. Way Stations • Arrive next to Way Station • Use robotic arm for all supplies • Arm places materials through top • No EVA USC 2004 AME 557 Space Exploration Architecture

  24. Sight • LCD monitors & cameras for piloting • Use HDTV cameras and signal • Located all around interior • Main screen in front • Screens act like windows for pilot • Night lights by cameras USC 2004 AME 557 Space Exploration Architecture

  25. How we will win • Minimize complications • Wheel size allows us to overcome most obstacles • Wheel base / spacing similar to HUMMER • We can run at night • Use of way stations USC 2004 AME 557 Space Exploration Architecture

  26. How we will win • We drive constantly • rotation cycle crew of 3 USC 2004 AME 557 Space Exploration Architecture

  27. How we will win • Traverse fast in Maria, slower in Highlands Finish race USC 2004 AME 557 Space Exploration Architecture

  28. How we will win • REUSEABLE ROVER!!! • Hybrid power day/night use • Towing capability • Dust USC 2004 AME 557 Space Exploration Architecture
