Multi-domain robotics competitions: the CMRE experience from SAUC-E to the European Robotics League Emergency Robots
(CMRE, 2019/06)
This paper details the experience of the Centre for Maritime Research and Experimentation (CMRE) in the organisation of several robotics competitions since 2010. In particular, the Student Autonomous Underwater Vehicle ...
Bandwidth efficient concurrent localisation and communication in underwater acoustic networks
(CMRE, 2019/05)
Localisation is essential for an Autonomous Underwater Vehicle (AUV) to perform its mission and to georeference any data acquired during the dive. When the AUV is part of a heterogeneous underwater acoustic network (UAN), ...
Efficient dense sonar surveys with an autonomous underwater vehicle
(CMRE, 2014/01)
An algorithm for the in situ adaptation of the survey route of an autonomous underwater vehicle (AUV) equipped with side-looking sonars was recently proposed. This algorithm immediately exploits the through-the-sensor data ...
Towards fully autonomous underwater vehicles in ASW scenarios: an adaptive data driven AUV mission management layer
(CMRE, 2019/06)
We present an adaptive, data driven Mission Management Layer (MML) to manage the phases (surveillance, track prosecution and target reacquisition) of the mission of AUVs operating as receiver nodes in a multistatic network ...
Cooperation and networking in an underwater network composed by heterogeneous assets
(CMRE, 2019/06)
Underwater communication and robot technologies have grown rapidly in the last decade. Systems made of underwater unmanned vehicles have moved from single vehicle deployments to systems comprising teams of assets. As of ...
Receiving and transmitting acoustic systems for AUV/gliders
(NURC, 2009/12)
NURC in the past years have focused its research on the use of AUV and more recently on gliders and is now developing littoral autonomous sensing networks based onthose sensors to perform missions such as mine warfare, ...
Dynamic placement of a constellation of surface buoys for enhanced underwater positioning
(CMRE, 2019/06)
This paper addresses the challenge of dynamically adapting the location of the nodes in an acoustic network to optimise the localisation performance of Autonomous Underwater Vehicles (AUVs) operating in the area. A dynamic ...
AUV-enabled adaptive underwater surveying for optimal data collection
(NURC, 2012/04)
A new adaptive strategy for performing data collection with a sonar-equipped autonomous underwater vehicle (AUV) is proposed. The approach is general in the sense that it is applicable to a wide range of underwater tasks ...
On-board real-time assessment of acoustic environmental parameters relevant to the estimation of sonar performance for autonomous underwater vehicles
(CMRE, 2019/05)
CMRE is evaluating the use of autonomous robots for the detection and tracking of underwater targets. Robotic detection and localization comes with many challenges, not the least of which is the requirement to maximize the ...
Ambiguity reduction of underwater targets in framework of topic modeling
(CMRE, 2019/06)
An unsupervised track classification approach based on appropriate discriminative and aggregative features derived from beamformed and normalized matched-filtered data is applied to sonar multistatic tracking and extended ...
