-The Stingray ROV (Remotely Operated Vehicle) is a revolutionary design in ROV technology.Designed as a small inspection class ROV, the Stingray has the performance characteristics of significantly larger and more powerful ROVs. The Stingray is a flexible and modular design, enabling the customer to easily and efficiently configure the system for a wide range of inspection and light work task operations. The ROV can be fitted with a range of video cameras, film or digital cameras, electronic flashes, NDT devices, navigation, and a range of manipulators. The modular design enables the customer to install a range of sensors and optional equipment. The expandability of the Stingray allows customers to undertake jobs with a small electric inspection class system that were previously possible only with larger, more expensive systems.

-The Stingray incorporates a proprietary digital control system developed by Under Control which utilizes an open system architecture based on an embedded Linux operating system. This robust control system further assures a high degree of system reliability. To assure ease of sensor integration the standard system has eight transparent full duplex serial ports, eight analog, and eight digital ports available for customer installed sensors.

-Utilizing commercially available off-the-shelf Tecnadyne 1/2 HP thrusters, the Stingray system has the power characteristics of much larger ROVs. The four brushless DC electric motors are magnetically coupled to the thruster propeller, with no thruster shaft seal. This extremely reliable and robust design assures a very high MTBF (Mean
Time Between Failure) for the thrusters.

-The Stingray ROV represents a major advancement in ROV technology and will provide a solid technology base for future Benthos ROV systems.
