The Marine Environmental Research Lab for Intelligent Vehicles (MERLIN) operates an Explorer Autonomous Underwater Vehicle (AUV) that serves as a potential platform for ocean surveys over a broad range of disciplines. MERLIN undertook a four year development program to improve both the capacity and autonomy of the vehicle by acquiring multibeam, side-scan and sub-bottom profiling sonars and developing...
The ability of an AUV to navigate an underwater environment precisely and for an extended period depends on its effectiveness at making accurate observations regarding its location and orientation. An AUV platform equipped with a side-scan sonar system has the potential to register the current sonar image with previously captured images for the purpose of obtaining information about the vehicle's...
Since 2002, the Marine Advanced Technology Center (MATE) has sponsored a nation-wide remotely operated vehicle (ROV) competition. This year's competition consisted of two mission tasks based on ocean observing systems, to be completed in less than 30 minutes at a depth of 12.2 meters. Taking a different approach from previous years, the MIT ROV team designed our main ROV, MTHR, not only to compete...
