Trajectory-Based Visual Localization in Underwater Surveying Missions

We present a new vision-based localization system applied to an autonomous underwater vehicle (AUV) with limited sensing and computation capabilities. The traditional EKF-SLAM approaches are usually expensive in terms of execution time; the approach presented in this...

Inertial Sensor Self-Calibration in a Visually-Aided Navigation Approach for a Micro-AUV

This paper presents a new solution for underwater observation, image recording, mapping and 3D reconstruction in shallow waters. The platform, designed as a research and testing tool, is based on a small underwater robot equipped with a MEMS-based IMU, two stereo...

Visual Sensing for Autonomous Underwater Exploration and Intervention Tasks

Underwater activities, such as surveying or interventions, carried out by autonomous robots, can benefit greatly from using a vision system. Optics based systems provide information at a spatial and temporal resolution higher than their acoustic counterparts. At...

Lenguaje ensamblador en el siglo XXI: desarrollo de videojuegos como elemento motivador

Este artículo describe el planteamiento adoptado por los autores en el apartado práctico de la asignatura Estructura de Computadores II del segundo curso del Grado en Ingeniería Informática en la Universitat de les Illes Balears, en la que los alumnos deben programar...

A Robot Application for Marine Vessel Inspection

Seagoing vessels have to undergo regular inspections, which are currently performed manually by ship surveyors. The main cost factor in a ship inspection is to provide access to the different areas of the ship, since the surveyor has to be close to the inspected...

Vessel Inspection: A Micro-Aerial Vehicle-based Approach

Vessel maintenance entails periodic visual inspections of the internal and external parts of the hull in order to detect the typical defective situations affecting metallic structures, such as coating breakdown, corrosion, cracks, etc. The main goal of project MINOAS...
