Designed to deploy and maintain underwater sensor networks, Leviathan included a mechanical gripper, rolling measurement device, solenoid release mechanism and a winch mechanism for retracting sensor modules. Leviathan featured modular electronics, which could be quickly removed from the robust welded aluminum container for service. It also featured a bright yellow, contoured fiberglass buoyancy device, for safety, control and to reduce snag points. The upper and lower sections of the vehicle could be separated to allow for quick replacement or maintenance of the vehicle accessories. Leviathan was used in filming for the upcoming movie, Spare Parts, debuting January 2015.
Designed to operation at depths of up to 40 feet, Phorcys’ mission to cap a free flowing oil well at the bottom of NASA’s Neutral Buoyancy Lab in Houston, Texas. Phorcys had tools to cut a collapsed header pipe, attach a retrieval line, secure a well cap to stop a flowing well under pressure, and conduct biological surveys of the area by retrieving water samples and animal specimens from the simulated seafloor. Phorcys had an open aluminum frame to provide minimum drag, which allowed for maneuvering through the flow of the oil well. This open design also allowed Phorcys to carry the well cap near center of thrust to allow more downward force for placement, and managed buoyancy with rigid aluminum canisters which resisted collapse at operation depth.
For the 2014 MATE mission task, Predator was designed to investigate shipwrecks off the coast of Lake Huron. Some of Predator's notable features include a sturdy aluminum frame, transparent bottom platform for pilot visibility, and controllable pneumatic buoyancy. The active buoyancy allowed Predator to lift a heavy 9 pound anchor to the surface quickly and safely, and could be quickly removed as a single unit by the deck crew. The electronics can is removable without disturbing or disconnecting the electronics for easy debug and repair. Other accessories include a wine bottle recovery mechanism, a rotary shaft with flexible fingers for retrieving a plate from the shipwreck, and a salinity sensor.
Reflecting advancements in Jesuit Robotics capabilities, Triton was our first ROV to include custom made printed circuit boards, parts that were fabricated by the team members with a CNC Mill, a precision depth sensor with a complex PID-based depth control algorithm, and our first implementation of a fiberglass/polystyrene buoyancy system. Triton was designed to survey and de-fuel WWII shipwrecks and included measurement devices, a simulated sonar scanner, a pneumatic lift bag, and a complex pump and storage system to simultaneously de-fuel the ships bunkers while back-filling with water to prevent collapsing the vessel.
