Vision statement

• By end of the course all students will be able to:– Prepare simplified models for motion of

• Submarines

• Autonomous Underwater Vehicles (AUV)

• Remotely Operated Vehicles (ROV)

– Check dynamic stability for AUV and manned submarines

– Describe how design parameters influence motion characteristics of AUV
