Marine Robotics

Course Description

Marine robotics is a branch of robotics that places emphasis on unmanned, autonomous marine vessels that find their application underwater and on water. Marine robotics has applications in exploration and conservation of marine species, habitats, and underwater cultural heritage, in aquaculture, maritime safety, offshore industry, and many others. This course focuses on navigation, guidance, and control of autonomous vessels (underwater and surface), as an upgrade on the topics of acoustic communication, sensors and mathematical modelling that are covered in the first part of the semester.

Learning Outcomes

  1. define marine systems and their classification
  2. distinguish unmanned underwater vehicles and their application
  3. explain the principles of underwater acoustic communication and principles of operation of acoustic modems
  4. explain the principles of operation of sensors and actuators used in marine vehicles
  5. analyze mathematical models of vessels
  6. design low level controllers for vessels
  7. design guidance controllers for vessels
  8. design navigation systems for vessels
