Good Ideas Borrow rather than buy –See what works on Okeanos Explorer –Educate community on contribution –New technical expertise on ship –Explore impact on ops tempo “Drop Cameras” Elevators

Scouting Need for scouting prior to using ROV Borrow Argus? Upgrade clump weight with thrusters, greater light/camera separation May want both towed and autonomous systems in long term (again, borrowing may determine relative contributions and whether bunk space is worth it)

ROV Needs Fiber optic gyro Servo controlled arm More lights Tool sled with –Slurp gun –Push core –Hydraulic drawer –Samplers: water, niskin –Sample boxes –Swing arms CTD Oxygen sensor Homers Redox gradient Digital still Magnetometer Multibeam/INS

Selling OE Emphasize universal access to data Provide a completely new way to study the ocean Empower the science party to use tools Make a consistent statement for how this will work

2nd Body Redesign frame to lengthen into Argus- type configuration ($10K) Add more lights ($75K/4 including more lights for main vehicle) Possible additional pan and tilt Longer term: low-power thrusters for vehicle ($100K plus engineering costs)

ROV Needs Fiber optic gyro $100K Servo controlled arm $180K More lights $75K Tool sled with –Slurp gun $10-40K –Push core –Hydraulic drawer $5K –Samplers: water, niskin $15K –Sample boxes $3K –Swing arms $5K CTD $10K Oxygen sensor $7K Homers $12K Redox gradient $2K Digital still $50K Magnetometer $8K Multibeam $30K (borrow AUV) Laser measure $5K TOTAL: ~$550,000

Other ROV Needs Front porch – extendable More than a foot of clearance for tool sled Reposition xbot Move arms down and out
