ROVs and AUVs

A Multidisciplinary Approach for Generating Globally Consistent Data on Mesophotic, Deep-Pelagic, and Bathyal Biological Communities

“…With the development of autonomous and robotic vehicles such as AUVs and ROVs, water depth beneath the ship no longer dictates the pixel resolution of acoustic maps, although bringing echosounders closer to the seabed reduces the area mapped (Wynn et al, 2014). As a result, most surveys now nest sampling, beginning with broad-scale, low-resolution shipboard surveys followed by zooming in with AUV, ROV, or physical sampling at locations of interest, and then adjusting the target pixel resolution, depending on terrain variability and ruggedness (Huvenne et al, 2018).…”

A Systematic Review of Remotely Operated Vehicle Surveys for Visually Assessing Fish Assemblages

“…Remotely Operated Vehicle (ROV) surveys use an unmanned underwater submersible that transmits real-time video observations and environmental readings (e.g., depth, compass heading) via an umbilical tether to the operator at the surface. ROVs are available in a range of systems from smaller observation-class ROVs (∼3-20 kg for mini and ∼30-120 kg for regular-sized models) to larger working-class systems (100-1500 kg for light and up to 5,000 kg for heavy-duty models), which vary in power, depth rating, accessibility, and additional payload capabilities (Baker et al, 2012;Romano et al, 2017;Huvenne et al, 2018) (Table 1). Since the first publication in 1996, ROV systems are becoming increasingly used as a deep-water survey method (Figure 2).…”

“…ROV surveys are novel video-based tool for assessing fish assemblages, yet have a number of strengths that could make them important tools in future biological surveys (Huvenne et al, 2018). These strengths include the ability to deploy high-resolution video (forward and downward looking) along fixed and repeatable transects on targeted seabed features, while maneuvering around complex substrate, and recording the track of the vehicle over base-maps (Linley et al, 2013;Macreadie et al, 2018).…”

Decision Making using Logical Decision Tree and Binary Decision Diagrams: A Real Case Study of Wind Turbine Manufacturing

“…LDT analysis is given in Reference [22] considering the interrelation between every single basic cause (BC), i.e., events that cannot be broken down into other causes, and including the logical operators 'AND' and 'OR', that define the interrelations between causes [23,24]. The non-basic cause (NBC) is an event that can be broken down into other causes.…”
