In the context of Remotly Operated Vehicule (ROV) for underwater application, connecting the robot to its docking station can be a significant challenge [2]. ROV have to navigate in a complex and unpredictable environment since the perception is limitted. Optical and Acoustic sensor can not be used is this kind of environment because blind spots can occur and short range obstacles may interfere...

The underwater robot is part of a project with “terrestrial–maritime” collaborative robots, whose mission recognition and rescue. From structural point view, some small changes were made in this study to the original robot. These consisted making supports hold two plexiglass tubes, since tube containing battery system larger. A larger was chosen because aim increase travel autonomy mini remotel...

A voltage sag is a major power quality problem at any load location, mainly due to short circuit faults. Its effects are especially clear in the industrial sector because they lead direct financial losses. The first and most important step getting rid of or least reducing find places network where it can happen. So, this article discusses creative way weak spots more likely drop. This innovativ...

For an effective integrity assessment of marine robotic in offshore environments, the elements’ failure characteristics need to be understood. A structured probabilistic methodology is proposed for operational (OFA) ROV. The first step assess likely mode ROV system and its support systems. This captures interaction induced events during operation. identified potential modes are further develope...

Remotely Operated Underwater Vehicles (ROVs) are emerging potential technology for ocean research, environmental and geochemical studies, mine hunting, surveillance, commercial usage. Due to their affordability, simplicity in handling deployment, appropriateness deep-sea diving, increased mobility, ability operate harsh settings, underwater vehicles—both autonomous remotely controlled—have grow...

Environmental monitoring of marine renewable energy projects is needed to reduce environmental uncertainties and enable sustainable commercial implementations. An Adaptable Monitoring Package (AMP), along with the support infrastructure required to perform maintenance of the AMP, is being developed to enable real-time environmental monitoring of marine renewable energy converters. The monitorin...

Human enteric viruses (HEntVs) are a major cause of water-related diseases. The prevalence of hepatitis A virus (HAV), rotaviruses (RoV) and enteroviruses (EnV) in Buffalo River waters was assessed quantitatively over a period of 12 months (August 2010 to July 2011). Seventy-two samples were collected from six sites, including three dams, and concentrated using the adsorption-elution method. Vi...

Large area mapping at high resolution underwater continues to be constrained by the mismatch between available navigation as compared to sensor accuracy. In this paper we present advances that exploit consistency and redundancy within local sensor measurements to build high resolution optical and acoustic maps that are a consistent representation of the environment. We present our work in the c...
