Cuttlefish (2016)

For the 2016 MATE mission at the NASA Neutral Buoyancy Lab in Houston, Texas, Jesuit Robotics developed Cuttlefish, our most advanced ROV yet. Optimized for outer space transport and designed to operate under the frozen crust of Jupiter’s moon, Europa, and in the deep waters of the Gulf of Mexico, At 17 Kg (37.4 lbs) and 58 cm (22.8 inches) in diameter Cuttlefish is Jesuit’s smallest and lightest ROV. It is fully equipped with tools for lunar exploration, oil sample recovery, deep water coral studies, and wellhead manipulation. Specialized tools include an adjustable rotating gripper, lifting clamps, a magnetic retriever, and temperature and depth sensors. These tools allow scientists to explore Europa, recover CubeSats, analyze the origins and effects of oil released by the Deepwater Horizon oil spill, and prepare an oil rig to be converted to an artificial reef.

Stingray (2015)

Devised for Arctic operations, Jesuit Robotics created Stingray for under-the-ice procedures and opportunities. Based in St. John's, Newfoundland, the 2015 MATE competition required an ROV that could replace pipe sections, survey icebergs and marine life, and service an underwater oil christmas tree. The exemplary feature for this ROV includes the modular subframes. Fully interchangeable, this feature allows the ROV to have three separate working modules that are easily replaced. Furthermore, this is an improvement for the serviceability of Stingray, enabling the deck crew to conduct swift repairs and operation while a subframe is under repair. Subframes were independent and fitted for each task. The accessories include two valve turners, a pipe clamp, and a laser measurement system as well as an external flow sensor known as EVE.

PREDATOR (2014)

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.

LEVIATHAN (2013)

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.

TRITON (2012)

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.

PHORCYS (2011)

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.
