REMUS 100 - Autonomous underwater vehicle

Remus 100 AUV exploded drawing

A stock REMUS 100 (if there can be said to be such a thing) is equipped with a side scan sonar from Marine Sonics Technology, an ADCP from Teledyne RDI, a light scattering sensor from Wetlabs, and a YSI CTD.  However, scientists, engineers, and even students have devised a number of additional packages and payloads that can be interfaced to the REMUS 100.

Configuration overview

The pictures and descriptions below demonstrate the flexibility and modularity of the REMUS 100 AUV:

  • Radiometric configuration
  • Turbulence measurement configuration
  • DIDSON configuration
  • GPS system configuration
  • Plankton pump configuration
  • Bioluminesence configuration
  • Hycode experiment configuration

This vehicle is equipped with up/down looking multi-spectral radiometers, a fluorometer and turbidity sensor, an OS-200 CTD, up/down looking ADCP and can be configured with a capillary waveguide hyperspectral spectrometer also known as the BrevBuster.

The BrevBuster was developed by Mote Marine Labs and Cal Poly State University and can be used on a general level to differentiate between different groups of phytoplankton. More specifically it is used to identify the presence of the red tide species, Karenia brevis off the west coast of Florida.

Additional applications for this vehicle include ground truthing for remote sensing sensors such as PHILLS II, bottom mapping and nearshore phytoplankton dynamics.
 

Turbulence measurement configuration

Arguably the most successful pure science AUV ever built. This vehicle has been operated for many years by Dr. Ed Levine for his research in turbulence measurement.

This Remus 100 vehicle is equipped with an up/down looking Teledyne RDI ADCP for current measurements, a pair of FSI CTDs, a Sontek acoustic Doppler velocimeter, and a shearprobe built at the University of Victoria.
 

DIDSON (Dual Frequency Identification Sonar) configuration

This vehicle is equipped with DIDSON - Dual frequency IDentification SONar

This vehicle is equipped with DIDSON - Dual frequency IDentification SONar. This forward looking sonar, designed by Ed Belcher of the Applied Physics Lab at the University of Washington records video-like images to hard disk even in water with limited or zero visibility. The vehicle is also equipped with a YSI CTD and a Teledyne RDI ADCP for current measurements.

GPS system configuration

GPS system configuration
REMUS 100 GPS system configuration.

This vehicle is equipped with a GPS system, allowing it to do long transects without transponders. It is also equipped with two deployable transponders, thus allowing it to do precision navigation without surfacing once its objective is reached. This vehicle is also equipped with a Marine Sonics Side scan Sonar, YSI CTD, a Teledyne RDI ADCP, and a Wetlabs light scattering sensor.

Plankton pump configuration

Plankton pump configuration

This vehicle is equipped with a plankton pump. It goes to a location and loiters there while collecting a sample, which it then stores. There is also a YSI CTD and Teledyne RDI ADCP onboard this vehicle. The plankton pump module can be removed and be replaced with a conventional REMUS 100 nose cap with a USBL navigation array, and a Wetlabs light scattering sensor.
 

Bioluminesence configuration

The vehicle is equipped with a bioluminescence sensor developed by CalPoly State University and The University of California, Santa Barbara. This is a second generation sensor. Its predecessor was the first system to provide a spatial view of bioluminescence distribution. The instrument is also equipped with a fluorometer and an OBS; the vehicle also has a up/down looking ADCP. This module can be removed and a replaced with a conventional REMUS 100 nose cap with USBL array.

Hycode experiment configuration

This module was built for the hycode experiment. It contains an up and downlooking radiometer and a fluorometer and spent the month of July, 2000 running daily 40 kilometer missions at LEO-15 off of New Jersey. Note the oversize LBL transducer in the front, which gave this vehicle a navigation and tracking range of well over 6 kilometers.
