TRITON National Funded Project experiments in Girona

From Monday 12th to Friday 16th of May, the TRITON national project experiments where held in Girona. The goal of these experiments was to localize an underwater panel with an acoustic ranging sensor. Once the panel is localized, the AUV homes to it and, once closer, using a vision-based system docks in it and performs an autonomous intervention. This intervention is split in two parts, first the vehicle manipulates a valve (open/close) and then connects and disconnects a hot stab. The first day was dedicated to system integration between the Girona500, the arm brought by the UJI team and the…

Early Stage Researcher (ESR) – Robocademy

( CLOSED ) Robocademy – The Maritime Robotics Research and Training Network  The Robocademy ITN will establish a European training and research network to develop key skills and enabling technologies in underwater robotics for the scientific and economic exploration of the oceans (e.g. offshore oilfield of the future). Through the close collaboration of leading research institutes, academia, industry, and SMEs in robotics, marine technology, marine science, and offshore industry, Robocademy will provide first-class training and research opportunities for ESRs. In well-defined and well-tutored PhD research projects, the Robocademy fellows will push the state-of-the-art in the area of robust, reliable and...

Angelos Mallios defends his PhD Thesis “Sonar Scan Matching for Simultaneous Localization and Mapping in Confined Underwater Environments”

This thesis presents the development of a localization and mapping algorithm for an autonomous underwater vehicle (AUV). It is based on probabilistic scan matching of raw sonar scans within a pose-based simultaneous localization and mapping (SLAM) framework.   To address the motion-induced distortions affecting the generation of full sector scans, an extended Kalman filter (EKF) is used to estimate the robot motion during that scan. The filter uses a constant velocity model with acceleration noise for motion prediction.Velocities from Doppler velocity log (DVL) and heading measurements from attitude and heading reference system (AHRS) are fed asynchronously and update the state….

El projecte TIC TAC a TV3

L’equip d’Udigital.edu va realitzar el passat dimecres dia 7 de Maig un taller molt especial dins el projecte TIC TAC. Els alumnes, d’escoles amb elevat percentatge d’immigració de les comarques gironines, van entrevistar el director de ViCOROB, en Rafael Garcia. En Rafa, els hi va explicar qui érem i què fèiem als alumnes, que, molt atents, van realitzar tota mena de preguntes.   UdiGital.edu intenta apropar la Universitat a la Societat, i sorgeix del treball interdisciplinar d’uns quants investigadors de la Universitat de Girona, que han unit esforços per dissenyar activitats i tallers per a nens i joves, barrejant la Tecnologia,…

ViCOROB al Fórum Industrial de l’Escola Politècnica Superior

Ahir dia 6 de Maig de 2014 es va celebrar a l’Escola Politècnica de la Universitat de Girona el 15è Fòrum Industrial, organitzat per l’Associació d’Estudiants d’Industrials (Aedi),amb el suport de l’EPS i del Patronat de l’EPS. El Fòrum uneix els interessos de les empreses de la demarcació amb les vocacions dels alumnes de l’EPS, en un entorn d’activitats i contactes directes que serveix per establir lligams i sinèrgies entre el teixit empresarial i la Universitat. Enguany, hi han participat 36 empreses i institucions.   El Fòrum consisteix en uns estands on es presenten les empreses i on els estudiants poden…

Coverage Path Planning for Autonomous Underwater Vehicles

Doctoral thesis “Coverage Path Planning for Autonomous Underwater Vehicles” By Enric Galceran, PhD student of the Doctoral Program in Technology Supervised by Dr. Marc Carreras Pérez   Abstract At present, a mission to survey the ocean floor with an Autonomous Underwater Vehicle (AUV) is typically planned by selecting a list of waypoints that then the vehicle will automatically navigate through while keeping a safe distance from the bottom. Nonetheless, this approach has major drawbacks: (1) it does not allow the vehicle to safely operate amidst protrusions on the sea floor; (2) when traversing rugged terrain, the vehicle is forced to…

7FP European Project MORPH: the next step in the future of underwater robotics

From 7-11th April 2014, a number of autonomous underwater and surface vehicles (robots) from several European institutions will be tested in the Costa Brava area, Spain. The tests will be carried out by 26 scientists from Germany, Portugal, Italy, France, and Spain. The major goal of these field trials is to demonstrate that the MORPH ensemble of vehicles can acquire data to map the sea bottom while operating in a cooperative manner and reacting to environmental conditions. The trials will focus on the execution of an optical and acoustic surveying mission with two surface and two underwater vehicles moving in…
