Abstract

SAUC-E (Student Autonomous Underwater Challenge - Europe) és la primera competició en robòtica submarina per a estudiants que es dur a terme a Europa. Inspirada en les competicions americanes, per a competir en el SAUC-E, un grup d'estudiants han de dissenyar i construir un robot capaç de dur a terme una missió predefinida per l'organització, de forma totalment autònoma. Un grup d'estudiants i professors de la Universitat de Girona (UdG) hem decidit afrontar aquest repte construint el robot ICTINEU AUV. Aquest robot aprofitarà eines de maquinari i programari desenvolupades els darrers anys en el nostre laboratori. Aquest article presenta el robot que estem desenvolupant i presenta resultats preliminars (simulació en temps real) de la seva arquitectura de control, mostrant la viabilitat de la proposta.

SAUC-E competition

SAUC-E competition

UdG project @Girona, Spain (2006). Inspired by the American competitions, SAUC-E (Student Autonomous Underwater Challenge - Europe) is the first underwater robotics competition for students to be held in Europe. To be eligible, a group of students must design and build a robot capable of carrying out, autonomously, a mission predefined by the organization in the underwater environment.

The objective of this competition is to challenge the next generation of engineers to design and build an Autonomous Underwater Vehicle (AUV), and then to perform realistic missions in the underwater environment. The event is designed to encourage young engineers and scientists to think about underwater technology and its future possibilities, as well as to foster interest in innovation and technology, and to encourage careers in this field.

Eight teams are involved in the competition:

  • Heriot-Watt University (UK);
  • International University Bremen (DE);
  • UdG - Universitat de Girona (ES);
  • University of Bath (UK);
  • University of Glasgow (UK);
  • University of Leicester (UK);
  • University of Southampton (UK).

The VICOROB-UdG team is a multidisciplinary team of students and professors from the Computer Vision and Robotics Group (ViCOROB) of the Universitat de Girona (UdG). Its main objective is to participate in the SAUC-E 2006 competition by building the ICTINEU AUV robot. This robot leverages hardware and software tools developed over the last years in the group's laboratories (e.g. real-time simulation and control architecture). In August 2006, the VICOROB-UdG team won the SAUC-E 2006 competition held in London (UK).

Within the VICOROB-UdG team, my work consists in developing a program for the real-time tracking of underwater objects. This program, which involves the use of image processing algorithms, aims at ensuring the robot's ability to complete two specific tasks during the mission. The first task consists in navigating towards a mid-water buoy and impacting it, the second consists in navigating towards a cross laying on the pool bottom and throwing a marker towards the center of the cross.

Abstract

Within 1857-1868, Narcis Monturiol developed the first Spanish submarine. Almost one hundred and fifty years later, a pioneer team of students of the University of Girona (UdG) decided to design and develop an Autonomous Underwater Vehicle (AUV) to face the Student Autonomous Underwater Challenge – Europe (SAUC-E). Our robot, called ICTINEU AUV, is the result of a multidisciplinary project involving undergraduate, graduate and Ph.D. students of industrial engineering and computer science. The prototype has evolved from the initial Computer Aided Design (CAD) model to become an operative Autonomous Underwater Vehicle (AUV) in the short period of seven months. The open frame and modular design principles, together with the compatibility with other robots previously developed at the lab, have been the main design philosophy. Hence, at the robot core, two networked computers give access to a wide set of sensors and actuators. The Gentoo/Linux distribution, with a 2.6 pre-emptive kernel, has been chosen as the onboard operating system. The real-time POSIX, together with the ACE/TAO CORBA-RT ORB, have been extensively used to develop the control architecture as a set of distributed objects with soft real time capabilities. Common software engineering practises have been applied to ensure software reliability including Unified Modelling Language (UML) design, extensive documentation using DoxyGen and the use of a Code Version Server (CVS) to handle the sharing of multiple code versions. Finally, in order to reduce the development time, concurrent engineering techniques based on Hardware In the Loop (HIL) simulation have been applied to overlap the hardware and software design and development.

Abstract

Pour assurer la disponibilité permanente de leur infrastructure informatique, les entreprises ont rapidement compris que la supervision était devenue une ressource-clé. Bon nombre de logiciels de supervision existent mais, parmi tout ceux-là, Nagios est très certainement le logiciel Open Source le plus répandu et également le plus suivi par la communauté de développeurs.

La supervision a trois objectifs principaux: prévenir les incidents sur le réseau par extrapolation des données fournies, agir rapidement dès qu'un système est noté en erreur et permettre l'analyse "post mortem" d'un problème grâce aux informations collectées.

Bien que Nagios soit reconnu comme difficile à installer et à configurer, il possède un nombre impressionnant de fonctionnalités telles que la surveillance de services réseau (SMTP, POP3, HTTP, NNTP, PING, ...), la surveillance de ressources machine (charge du processeur, utilisation du disque, ...) et la conception simple des "plugins" qui permet à des utilisateurs de développer facilement leur propre service de vérification.

Dans le cadre de ce travail de fin d'études (TFE), nous avons mis en place une supervision centralisée de l'infrastructure informatique de EASI, une gestion d'alarmes en cas de problèmes sur le réseau et une notification des alertes par email. Pour effectuer cela, nous avons non seulement utilisé les plugins standards de Nagios mais nous avons également développé nos propres plugins.

De plus, nous avons créé un mode multi-utilisateurs avec une authentification via l'annuaire LDAP (Lightweight Directory Access Protocol) de EASI et nous avons sécurisé les échanges d'informations entre les serveurs Nagios par un système de clés publiques et privées. L'objectif à terme est d'étendre cette architecture à l'ensemble des clients de EASI.

Centralized supervision

Centralized supervision

ISIB project @Brussels, Belgium (2005). To ensure the permanent availability of their Information Technology (IT) infrastructure, companies have quickly realized that supervision had become a key resource. Many supervision software are available but Nagios is certainly the most common open source software and the most followed by the developer community. In this work, we developed a centralized supervision system of the IT infrastructure of the EASI company.

The main features of supervision are:

  • the network supervision: monitoring of hardware components;
  • the system supervision: application and software monitoring;
  • the notification: sending of alerts by email, sms, phone or audible warning;
  • the execution of commands: restart of an application in case of failure;
  • the mapping: visualization of the network through a map or chart;
  • the report file: complete history of the supervision system.

Within the framework of this work, we developed a centralized supervision system of the IT infrastructure of the EASI company, as well as a management of alarms in the event of network problems and an alert notification by email. To do so, we not only used the standard plugins of Nagios but also developed our own plugins.

We also created a multi-user mode with an authentication based on LDAP (Lightweight Directory Access Protocol) and secured information exchanges between Nagios servers by a public/private key system. The objective in the long term is to extend this architecture to all EASI customers.
