Learning about the climate change: effects on the Arctic

We set sail for Ny-Aalesund, an island situated on Spitsbergen, north-west of Longyearbyen, in Oscar II land. One of the northernmost city in the world. Now deemed, as an international research center in the Arctic. Ny-Aalesund, counting 11 institutions from 10 countries.   As we had an opportunity to be part of training program organized by the Italian station support the CNR‘s studies on climatic changes. where the aim of their research focuses on environmental and climatic studies of ice and marine sediments, that plays a mandatory role to avoid the disappearance of the glaciers covering some areas of the Arctic Ocean.   When we arrived there, a thin layer of white snow was covering almost everything; we didn’t have the impression that this is summer and this is how nature is supposed to express its color, during this period of the year. It was beautiful of course, we couldn’t…

Laser 3D Sense Technology towards the market

The Laser 3D scanner technology developed and patented by the University of Girona is one step beyond the state of the art of underwater 3D perception. It is the result of a PhD thesis in Underwater Robotics and 3D Perception done by Albert Palomer and tutored by Pere Ridao, Josep Forest and David Ribas that will be soon defended.   L3S, as an easy to integrate system, will allow the end user to gather online 3D information of a target scene from a moving vehicle at a resolution where the objects can clearly be identified. Moreover, it will also allow the user to have a more accurate idea of the inspected area at a very high resolution,at the cost of a longer scanning time, being able to detect cracks from 1mm, find targets, support on the assisted operation of autonomous intervention tasks, quantify volumes,… covering real market needs.   This…

SOUNDTILES technology presented at Oceanology International London

At ViCOROB, we do research on Underwater Vision and Robotics. One of the developed technologies in the last years, currently being valorized in the context of SOUNDTILES project (Ref.: 2016 PROD 00130) consists on the development of a tool for automatic processing of sonar mosaics, a breakthrough in the current technologies available commercially.   Natàlia Hurtós presented this technology in front of a commercial audience in the most important fair of underwater technologies, Oceanology International, that took place in London (UK). In the same event, ViCOROB team had the chance to meet with industry key actors, like the American company SoundMetrics.   These activities have been carried out on the effort that the lab is doing towards bringing this technology to the market in the near future in the framework of SOUNDTILES project.        

EU Marine Robots Kick Off meeting takes place in Porto

The EUMR Kick Off Meeting was successfully completed in Porto, Portugal on the 1st and 2nd of March, 2018. The meeting facilitated partner introductions and allowed a detailed examination of all project future activities and goals.   During the two day meeting, partners had the opportunity to discuss various topics, including project objectives, the governance structure, milestones, management processes and tools, project roadmap and partners responsibilities.   This meeting was a great chance to consolidate the consortium, project management key points and to map the road ahead!   Text: EU Marine Robots   More about the project

Arriba el Nadal

Res no s’acaba i tot comença. Vénen mecànics de remença Amb olis nous de llibertat; Una Veu canta en recompensa: Que a cal fuster hi ha novetat. Des d’Alacant a la Provença Qui mor no mor, si el son és clar Quan neix la llum en el quintà.   Fragment del poema “Ho sap tothom, i és profecía” de J. V. Foix,   Que tingueu unes festes plenes de llum, colors , regals i torrons!! Wishing you the best for 2018!   Us recordem que del 25 desembre a 8 de gener restarem tancats. We will be closed from December the 25th to January the 8th 2017.

Online Path Planning for Autonomous Underwater Vehicles under Motion Constraints

Doctoral thesis “Online Path Planning for Autonomous Underwater Vehicles under Motion Constraints” By Juan David Hernández Vega Supervised by Dr. Marc Carreras   Abstract Thesis submitted to the University of Girona in fulfillment of the requirements for the degree of Doctor of PhilosophySince their beginning in the late 1950s, the capabilities and applications of autonomous underwater vehicles (AUVs) have continuously evolved. Their most common applications include imaging and inspecting different kinds of structures on the sea floor as well as collecting oceanographic informa-tion: biological, chemical, and even archaeological data.   Most of these applications require a priori information of the area or structure to be inspected, either to navigate at a safe and conservative altitude or to pre-calculate a survey path. However there are other applica-tions where it’s unlikely that such information is available (e.g., exploring confined natural environments like underwater caves). In these scenarios, AUVs must operate in unexplored…

Six members of ViCOROB attend the Breaking the Surface summer school in Croatia

BtS (Breaking the Surface) is a summer workshop that encourages interaction and the exchange of knowledge and experience about the maritime robotics field and its applications. In 7 days, participants get first-hand knowledge about the latest in scientific research and results, technological achievements as well as hands-on experience in working with complex and modern underwater systems.   In the event, Nuno Gracias and Ricard Campos gave a tutorial on “Omnidirectional vision for underwater robots”. Marc Carreras gave a talk on “Towards persistent AUVs for seabed inspection”. Khadidja Himri, Patryk Cieslak and Joseta Roca also attended to the workshop.   Along the 7 days, the team had the chance to interact with other international labs and companies. Also, in the framework of the event, an EXCELLABUST project meeting was organized for the planing of the following 12 months of project, including topics like EMRA18 workshop that is going to take place…

Successful participation of our team in European Robotics League competition 2017

ERL Emergency 2017 occurred in Piombino on 15-23 September, is an European Robotics League competition or what researchers calls Champions League of Robotics, instigated by the catastrophic nuclear accidents that touched Fukushima, Japan, in 2011. The challenge collecting among 130 participants from 16 universities and companies, came from 8 European countries. In the competition, robots from different domain: air, land and sea cooperate in order to complete a task within a set period. These experience also provide great opportunity to broadcasting technologies and improving relations with researchers with similar interests. where the main goal remaind to advance and improve in technological skills and international cooperation.   Khadija Himri PhD student shares her experience in European Robotics League ERL17 competition:   “This academic year was marked by my first experience with participating in European Robotics Leagues ERL17 competition, the principal goal of the competition aimed to test Robot’s abilities of deployment…

ROBOT LEARNING APPLIED TO AUTONOMOUS UNDERWATER VEHICLES FOR INTERVENTION TASKS

Doctoral thesis “Robot Learning applied to Autonomous Underwater Vehicles for intervention tasks” By Arnau Carrera Viñas Supervised by Marc Carreras, Narcís Palomeras and Petar Kormushev   ABSTRACT The interest in performing underwater tasks using AUVs has been growing over the past few decades. The initial focus was on the exploration of underwater areas, performing survey trajectories harvesting data to build bathymetric maps or photo-mosaics. Later the focus of research switched to performing inspections of underwater structures or elements (e.g., pipelines) which required more complex behaviours and localization methods. Advances in these fields have awakened the interest of the community in using AUVs to perform intervention tasks, replacing ROVs and manned submersibles. This replacement offers the possibility of automatizing tasks, increasing the efficiency and repetitively, as well as reducing cost, time, and the equipment needed to perform an underwater intervention. I-AUVs open the door for more companies and scientists to increase the frequency of…
