REMUS 6000 - the deepest member of Hydroid's growing family of Autonomous Underwater Vehicles - AUVs!
The REMUS 6000 AUV / marine robot was designed under a cooperative program involving the Naval
Oceanographic Office, the Office of Naval Research, and the Woods Hole Oceanographic
Institution - WHOI, in support of deep-water autonomous operations. The REMUS 6000
AUV boasts the same proven software and electronic subsystems found in our highly
successful REMUS 100 AUV, with a depth rating, endurance, and payload that allow
for autonomous operations in up to 6000 meters of water.
Auxiliary Support Equipment / Vehicle Safety Features
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.
Communication and Tracking
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 along with position updates if required. The HiPAP
(KONGSBERG acoustic underwater positioning and navigation system) or Ranger positioning systems provide acoustic aiding to the on-board IMU (Inertial Measurement Unit) and DVL (Doppler Velocity Log) 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 localisation 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 localisation. If two-way satellite communication is enabled, a revised
mission plan can be sent to the vehicle from anywhere in the world.
