The primary objective of the project is to build Remotely Operated Vehicle (ROV) underwater/ AUV for surveillance and monitoring purpose by intelligent Novigation under water. To achieve the above objectives ROVs are developed at NIT Rourkela and testing is going on to see the effectiveness of developed ROVs. AI techniques and rule-based techniques are used to control the ROVS. Till now ten jourNol papers have been communicated to various jourNols related to the research.
