Characterization of Rollagons

1
Characterization of Rollagons

• Maneuverability - one point for ditches, trees,
  turning, and standing objects
• Effectiveness - feasible land propulsion system
• Transition - around 1 minute from water system
  to land system possible interference from rocks
  or objects on the ocean bottom
• External force effect - waves and wind could
  effect our hydraulic boons possibility of
  foreign objects
• Size/deck arrangements - rollagons would take up
  roughly half of deck space
• Maintenance - would not need any significant
  amount of maintenance.
• Well deck storage - the rollagons do not inhibit
  the vehicle from fitting in the boat
• Noise/vibration - rollagons will be moderately
  quiet
• Technology risk - not proven on an ACV at this
  moment
• Ease of acquisition/manufacturability - the size
  of rollagon that we would need for the ACV would
  be much larger than any of us are familiar with

Trade-off Requirements

• Maneuverability - rocks, ditches, trees, turning,
  standing objects 2 points for each (subtract
  from 10)
• Effectiveness - 1 or 10 (yes or no)
• Transition - 1/2 point for every 15 seconds of
  transition 1 point for each obstacle sand bar,
  well deck, rocks, waves
• External Force Effect - waves, wind, rain,
  current, foreign object damage 2 points for
  each
• Weight - of the system divided by the weight of
  the vehicle
• Power - power required for the propulsion system
• Size/Deck Arrangements - foot print area (on
  deck) divided by available deck area Available
  deck whole deck-cargo deck-machinery

Trade-off Requirements

• Maintenance - 1, 5, 10 (1little regular
  maintenance bike 5moderate maintenance
  car 10significant maintenance airplane)
• Well deck storage - yes or no (able to fit into
  the boat storage)
• Cost - the price of the propulsion system
• Noise/Vibration - 1, 5, 10 (1little noise
  computer 5moderate noise loud
  10significant noise ear protection)
• Technology Risk - 1, 5, 10 (1proven on ACV
  5Not proven on ACV, but used elsewhere
  10untested)
• Ease of acquisition/Manufacturability - 1, 5, 10
