This thesis starts by introducing the facilities and systems used while conducting experiments. It then goes on to present the methods and techniques used for rendering and superimposition, to project a curved path onto the video feed from a Remotely Operated Vehicle. Next, path-generation and path-following are discussed, and the maneuvering problem is introduced. The Serret-Frenet equations for curves are introduced. Then the controller, observer, and user input scheme used in this thesis are presented. The result from the tests on path-following are then presented and discussed. The thesis then goes on to explain the implementation of simultaneous path-generation and -following. The results from these tests are presented and discussed. From the laboratory experiment it was found that path-following and simultaneous path-generation and -following have a definite application for underwater ROVs, but some changes need to be made to optimize the performance. For simultaneous path-generation and -following, the algorithms need to be improved, both for computational performance and for physical performance.
