A midsized UUV designed for easy transport and maximum versatility, the REMUS 600 (the US Navy MK18 Mod 2 and LBS AUV Program vehicles) is a highly configurable vehicle with a maximum operating depth of 600 meters. Able to be deployed from vessels as small as an 11 meter RHIB and boasting a maximum mission duration of 24 hours, the REMUS 600 can be outfitted with a broad range of sensors to meet the requirements of nearly any mission.
The positively buoyant REMUS 600 has been designed to operate to depths of 600 meters. This highly versatile system can also be ordered and configured for 1500 meter operation.
The REMUS 600 delivers unprecedented endurance, with mission duration capability of up to 24 hours. Upon mission completion, simply recharge the internal battery. (Endurance is subject to speed, sensors and battery configuration).
The REMUS 600 has been designed with modularity in mind. The vehicle can be reconfigured for a wide variety of customer payloads. The vehicle is comprised of a series of hull sections that are quickly separated for vehicle reconfiguration, maintenance and/or shipping.
Designed to carry a range of payload options–standard and custom, wet and dry–depending on your mission requirements. It has the flexibility to exchange payloads or upgrade at a later date.
The REMUS 600 incorporates the same proven vehicle autonomy used in the complete family of REMUS vehicles. The stable and proven software makes vehicle maintenance, mission planning, and data analysis fast and easy. Windows® operation, quick-look indicators, quality control checks and a sophisticated data export capability all add to the flexible nature of this software package.
The REMUS 600 is based on the same leading edge technology that has brought the REMUS 100 to the forefront of autonomous operations.
The Hydroid LARS is designed to function off the stern or midship of a vessel and is field proven with the REMUS 600 and REMUS 6000 AUVs. The self-contained LARS can extend the operational weather window of the AUV by allowing launch and recovery in conditions up to Sea State 5 while retaining the flexibility to operate from any vessel of opportunity. When mounted on the stern of a ship, the LARS has a 5.5 ft. x 10 ft. footprint, and requires less than 15 horsepower when operational.
Certain Hydroid AUVs can be configured with autonomous docking capability. The systems includes:
32.4 cm (12.75 in); diameter varies depending upon module (for 600 m depth configuration)
Min length ~2.7 m (~9 ft) Max length ~5.5 m (~18 ft); length varies depending upon module configuration
Min weight ~220 kg (~500 lbs) Max weight ~385 kg (~850 lbs); weight varies depending upon module configuration
600 meters (1500 meter configuration available)
5.4 kWh rechargeable Li-ion battery; (Second 5.4 kWh battery tray is optional), exchangeable battery option available
Typical mission endurance is up to 24 hours in standard configuration. Subject to speed, battery and sensor configurations
Direct drive DC brushless motor to an open two bladed propeller
Up to 2.3 m/s (4 knots) variable over range
(3) independent control fins providing yaw, pitch and roll control. Altitude, depth, yo-yo and track-line following provided. Optional forward fins available for heading control during bottom tracking with a cross current
(2) connectors, one for shore power and one for shore data. Alternatively, 802.11G wireless network (Wi-Fi) provided via dorsal fin antenna
Ground fault, housing leak detection and all sensors and systems have operational go/no-go fault indicators
Inertial, Long Baseline (LBL) Acoustic, SBAS enabled GPS, Ultra Short Baseline Acoustic and Acoustic Transponder
Acoustic modem, Iridium modem, Wi-Fi 2.4 GHz, 100 Base-T Ethernet (standard), 1000 Base-T Ethernet (optional)
REMUS Vehicle Interface Program (VIP), GUI-based laptop interface for programming, training, documentation, maintenance and troubleshooting
The REMUS 600 utilizes the same Vehicle Interface Program (VIP) as our family of vehicles. This VIP simplifies vehicle maintenance, mission planning, vehicle checkout and data analysis. Communication between the vehicle and the host is conducted via a 100 Base-T Ethernet connection or Wi-Fi. Among other features, the VIP includes:
All Hydroid AUVs have core systems designed to monitor the status and operation of essential components. Health monitoring includes batteries, motors, sensors and communications as well as conditions such as depth or water ingress. If an abnormality is detected, then an alarm is raised. During supervised missions this will be transmitted to the operator enabling them to decide if the vehicle should return from its mission. When the vehicle is operating autonomously, the response to an alarm is determined by the preselected response listed in the mission plan. This could include an emergency abort to preserve vehicle security.
Operators can monitor the AUV’s progress and status via an acoustic link. This also enables amendments to the mission plan to be sent to the vehicle. The HiPAP or Ranger positioning systems provide acoustic aiding to the on-board IMU and DVL equipment to make the real-time position solution as accurate as possible. Some Hydroid AUVs also transmit real-time side scan and bathymetry data back to the operator acoustically. This data is displayed on the payload computer screen to give the operations team confidence that the mission is progressing as planned and there are no gaps in the data. When the AUVs are on the surface, they can communicate via Wi-Fi or radio with the operator. They are also equipped with GPS receivers to update the IMU position with the most accurate information available.
To assist with emergency localization and recovery operations, the AUVs can be equipped with emergency radio beacons, strobe lights and satellite communications. In the event of an emergency ascent, the position and status of the vehicle can be sent via the Iridium network to the operators and home base simplifying post emergency localization. If two-way satellite communication is enabled, a revised mission plan can be sent to the vehicle from anywhere in the world.
