Autonomous Vehicles in Support of Naval Operations

2005, National Academy of Sciences AUV

“Joystick control”

• Legacy approach

• Expensive deployment

• Data through tether

ROV

OneSubsea uROV

“Supervised autonomy”

• Pragmatic approach

• Prescribed real-time data

• Agile

“Fire and forget”

• Future of IMR

• Trust issue around

sensitive infrastructure

• Development cost
