This work presents a new approach to reconstructing surfaces of underwater structures from stereo images and sonar scans collected with a micro-ROV on the islands of Malta and Gozo. Using a limited sensor load, sonar and small GoPro Hero2 cameras, the micro-ROV is able to explore small hard to reach water systems and gather data. Our algorithm is able to reconstruct geometric models of explored...

ii Declaration We hereby declare that the project work entitled " AQUABOT: Hydro view Real-Time Video Streaming Remotely Operated Vehicle " submitted to the Sri Lanka Institute of Information Technology is a record of an original work done by us, under the guidance of our Supervisor Mr. Anuradha Jayakody. This project work is submitted in the partial fulfillment of the requirement for the award...

Remote Operated Vehicles (ROVs) are used extensively for salvage operations, ocean floor surveying and numerous inspection activities that support a wide range of underwater commercial activities. In deep water (greater than 1000 ft) an ROV is the platform of choice because of the depth and endurance limitations for human divers. The key disadvantage to an ROV is the requirement for the long te...

The behaviour of eight large benthopelagic fish taxa was analysed using video records collected with an ROV on the mid-slope of the Bay of Biscay. The studied species were roundnose grenadier (Coryphaenoides rupestris), orange roughy (Hoplostethus atlanticus), deep-sea scorpionfish (Trachyscorpia cristulata echinata), and black scabbardfish (Aphanopus carbo), as well as individuals belonging to...

Estimating the area of seabed surfaces from pictures or videos is an important problem in seafloor surveys. This task is complex to achieve with moving platforms such as submersibles, towed or remotely operated vehicles (ROV), where the recording camera is typically not static and provides an oblique view of the seafloor. A new method for obtaining seabed surface area estimates is presented her...

Remotely Operated Underwater Vehicle (ROV) is a submersible robotic system, used to examine various underwater characteristics and controlled by operators from shore. The applications of ROV are widely diverse, especially for exploration marine industry. This research investigate pressure drag on vehicles using the CFD approach. A low-cost mini with 300 mm length was determine hardware material...

Nowadays, the surveillance and inspection of underwater installations, such as power and telecommunication cables and pipelines, is carried out by trained operators who, from the surface, control a Remotely Operated Vehicle (ROV) with cameras mounted over it. This is a tedious, time-consuming and expensive task, prone to errors mainly because of loss of attention or fatigue of the operator and ...

The integrated maneuver and control structures for a Remotely Operated Vehicle are presented in the context of the developments of ”IES Inspection of Underwater Structures” project. The project concerns the design and implementation of an advanced low cost system for the inspection of underwater structures based on a Remotely Operated Vehicle (ROV). First, the sub-systems of the IES system are ...

This paper presents a description of a very low cost underwater vehicle project, specifically about a remotely operating vehicle (ROV). The main motivation of this research is based on the fact that underwater robotics in Brazil is a recent scientific domain, particularly in experimental aspects. A few project specifications were established, and the actuators, sensors, structure and onboard el...

Starting in 2004, the Department of Mechanical Engineering at Rowan University introduced a new tool into its program: Remotely Operated Vehicles (ROVs). The tool is used at different aspects ofeducation. As a coursework project, graduating ME seniors researched, designed, built, competed and reported with underwater ROVs to assess their design skills before heading out to start their careers. ...
