To this end, Envirobot has been designed to have more endurance, flexible computational power, long range communication link, and versatile flexible environmental sensor integration. Its low level control is powered by an ARM processor in the head unit and micro processors in each active module. On top of this, integration of a computer-on-module enables versatile high level control methods.

However, autonomous underwater vehicles (AUVs) have a significantly different intervehicle communication regime than other branches of robotics due to the physical realities of the ocean as a communication medium. Goby3 is a new middleware, the first specifically designed to address intervehicle, interprocess, and interthread communication on AUVs in a unified manner. Goby3 is based on C++11 and is minimally restrictive on the types that can be published and subscribed using it. A reference implementation is given that uses C++ shared pointers for interthread, ZeroMQ for interprocess, and Goby-Acomms for intervehicle communication. This implementation is shown to give similar or better performance to existing middlewares.","PeriodicalId":416057,"journal":{"name":"2016 IEEE/OES Autonomous Underwater Vehicles (AUV)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133343983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ghost fishing refers to derelict fishing gear which continues to function and induce mortality of aquatic organisms without human control. So far, derelict and lost fishing gears are a major global problem. A comprehensive solution is proposed here for dealing with the issue of the ghost fishing gear. This solution includes hardware and software solutions, respectively. In terms of hardware, a light weight, hand-carried AUV, an omni-directional LED light ball which is a passive optical communication device are used. In terms of software, there are three apps running on mobile devices: the registration system of fishing gear for the owner, checking the fishing gear by the coast guard during the departure examination and location logger of fishing gear when deploying and recovering the fishing gear. To implement the idea of hunting the ghost fishing gear, USD$300,000 is required. This work will be executed over three years. In the first year, small light balls with passive optical communication and Bluetooth will be developed. An AUV with optical transceiver will be developed and tested based on a well-established prototype AUV in the second year. In the third year, the apps for fishing gear management will be built. This system will be tested in the field where an AUV searches light balls attached on fishing gears. Effective management and control of fishing gear can manage the incidence of ghost fishing gear. It is expected that the system not only protects marine life but also reduces marine litter. This work provides a view of using the AUV and communication technology to drive commercial fisheries towards sustainability.","PeriodicalId":416057,"journal":{"name":"2016 IEEE/OES Autonomous Underwater Vehicles (AUV)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133719555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents preliminary results of a differential pressure sensing system using an extension of the Pitot equation capable of providing instantaneous flow speed estimation, including yaw angles from ±45°. In contrast to systems with similar configuration based on absolute pressure sensor approaches, the differential system makes use of the pressure between two points on the sensor head, reducing the number of necessary sensors by half. The theoretical system performance and physical prototype are compared using computational fluid dynamics and flow tunnel tests from 0-0.5 m/s and angles of attack up to ±45°. The proposed speedometry device has a small form factor, uses inexpensive commodity hardware, is geometrically simple, accurate (mean absolute error of 0.024 m/s) and has low power consumption (<; 10 mW for each sensor) making it suitable for a wide spectrum of underwater vehicles.","PeriodicalId":416057,"journal":{"name":"2016 IEEE/OES Autonomous Underwater Vehicles (AUV)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116312099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the large number of parameters, which can number to hundreds, it is difficult to estimate such models. Moreover, AUV capabilities like thrust vectoring increases the non-linearity of the model. We suggest solving the problem of modelling AUVs with the help of a rectifier activated multilayer perceptron, making use of their motion data and control inputs. We also provide details on the optimisation of our model and compare its performance with that of a standard system identification technique. Although the rectifier neural network's performance was tested for a typical streamlined AUV with a Voith-Schneider thruster, the model presented here is general and can be easily extended to other systems.","PeriodicalId":416057,"journal":{"name":"2016 IEEE/OES Autonomous Underwater Vehicles (AUV)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129147603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method uses the sonar images of moving agent obtained by forward-looking sonar. To detect the location of the agent in the sonar images, the convolutional neural network is applied.
