Technical information on selected AUVs and ROVs used within the NORUS framework and NORUS workshops
Iver2 Autonomous Underwater Vehicle (AUV)
Maximum Operating Depth: 100m
Battery Life: ~12hrs at 2.5kts
(see above link for more details)
Average Mission Duration/Range: 5-10 Hours, 5-15 km
AIRMAR Water Temperature Sensor
WHOI Acoustic Modem
The Iver2 vehicle is a revolutionary, commercial design for AUVs. OceanServer has devoted the last 6 years to building a new class of rugged and reliable vehicles starting around $50,000 USD. These next generation vehicles are designed for everyday use, minimal downtime and mission planning in just minutes. Iver vehicles are used by customers around the world in both salt and fresh water for a variety of uses including bathometry, environmental monitoring, search and recovery, surveys and general data collection.
The Iver2 at Cal Poly, San Luis Obispo is currently operated by the Department of Computer Engineering. Sensor development and field testing are performed year round by students. Currently, the Cal Poly Iver2 is undergoing testing related to under-ice navigation. The Cal Poly Iver2 will be in Svalbard, Norway in January, 2010 as part of the NORUS program.

The VideoRay Pro ROV series is the system of choice for intensive, underwater operations. All Pro models have an open architecture that accommodates a wide variety of tools and sensors. The Pro 3 S incorporates the features of the Pro as well as a convenient Tether Deployment System.
The VideoRay ROV at Cal Poly, San Luis Obispo is currently maintained and operated under the supervision of Dr. Chris Clark from the Department of Computer Science. It is primarily used for senior projects and master's theses as well as ongoing research.
REMUS 100 vehicle (AUV)
The Remote Environmental Measuring UnitS (REMUS) 100 is an autonomous underwater vehicle (AUV) used for surveying underwater environments. The REMUS 100 was developed by Woods Hole Oceanographic Institute and is currently manufactured by Hydroid, Inc. REMUS vehicles can be outfitted with a number of sensors to measure water column dynamics (ex. fluorometer, ADCP, CTD, optical backscatter, etc).
REMUS vehicles use Long baseline (LBL), and Ultra short baseline (USBL) to navigate through the water column in an acoustic transponder network. The REMUS also uses GPS, compass heading, and Doppler-assisted dead reckoning to navigate a mission in the absence of an acoustic transponder networks.
The REMUS is easy to program, quick to launch, and allows for survey missions of up to ten hours. This AUV offers continuous spatial and temporal data sampling; making this a high-resolution survey technique. The REMUS is particularly useful in coastal oceans environments for characterizing and interpreting the complex and dynamic nature of these systems.
