Test Report – J5 at 12h

By | Uncategorized | No Comments

Last nigh, we tough we found the cause of our problems with the hydrophones. We thought we found it and that we applied the necessary patch. Unfortunately, the test of this morning brought use back directly to the startup position. To big problems, big means. This afternoon, we revisited all the hydrophones and their physical interfaces. We have still been able to test the navigation. Like every day at the Transdec, we are really surprised with the data that we receive. With the exact same configuration as yesterday, the Sonar does not give us the same results. What was yesterday…

Compte Rendu de Test – J5 à 12h

By | Uncategorized | No Comments

La nuit dernière, nous croyons avoir trouvé la source du problème des hydrophones. Nous pensons avoir trouvé et appliqué la bonne solution, mais les tests de ce matin nous ont renvoyé à la case départ. Aux grands problèmes les grands moyens. Cet après-midi, on révise tout sur les hydrophones, de leur fonctionnement physique à l’interface usage. Nous avons tout de même pu tester la navigation. Comme à chaque jour au TRANSDEC, on reste toujours un peu surpris des données que l’on reçoit.  Avec les mêmes configurations qu’hier, le sonar ne nous donne pas les mêmes résultats. Ce qui était trois…

Test Report – Test 2

By | Uncategorized | No Comments

After we have fixed the thrusters (by changing the navigation board), we have been able to do two tests in a row at 10am35 and we had a test of 1h15. The goal of the test was to acquire the data with the sonar and the vision on the buoys and the fence. We also took advantage of Dave presence to go through the gate and qualify for the semi-finals. We acquired enough data to be able to work on the logs and answer the question that we have: The value of the DVL drift Are the walls visible with…

Robosub 2016 – Day 3: The Beginning

By | Uncategorized | No Comments

Today, we worked on improving our effectiveness during the tests. The hotel wifi being not as good as we would like it to be, we had to setup a Git server on a raspberry-pi so we can access our code base without the internet. We did a few scripts to ease the configuration changes on the workspace. Alexi worked on the CAN UI in order to increase the rapidity of the latter and ease its usage during the debugging of the hydros. Also, ROS allows us to log the messages the go through the network during the execution time. Pierluc…

Robosub 2016 – Jour 3: Le Commencement

By | Uncategorized | No Comments

Aujourd’hui nous avons travaillé sur notre efficacité en test. Le wifi de l’hôtel n’est pas super, alors on a ‘’setupé’’ un serveur git sur un raspberry-pi afin d’avoir le code sans accès internet. On a fait quelques scripts pour faciliter les changements de configurations du workspace. Alexis a travaillé sur le UI du CAN afin de l’améliorer et le rendre plus rapide et facile à utiliser lorsqu’on debug les hydros. Aussi, avec ROS il est très facile de logger tous les messages qui transitent durant l’exécution. Pierluc s’est occupé d’ajouter au serveur de vision la possibilité de lire les vidéos…

Robosub 2016 – Day 2: Preparations

By | Uncategorized | No Comments

First full day in San-Diego for the team. Everyone agrees that California’s weather is completely unique. For breakfast this morning: coffee and getting the submarine. We have no time to waste. Unless a little inconvenient, the sub arrived to our room the fun part could finally begin. On the software side, the team cleaned the code and we developed a user interface for the mapping system to modify the settings and observe the effects easily. On the mechanical and electrical side, we reassembled le submarine. Everything is well … but we need to mention Jéremie’s cold sweat when he found…

Robosub 2016 – Jour 2: Préparations

By | Uncategorized | No Comments

Première journée complète à San Diego pour l’équipe. Tout le monde s’entend pour dire que la météo de la Californie est complètement unique. Le matin, à l’horaire, café et aller récupérer le sous-marin. Malgré quelques désagréments techniques, le sous-marin s’est retrouvé dans notre chambre et le fun a pu commencer. Côté logiciel, le code a été finalisé. Une Interface utilisateur a été développée pour modifier rapidement les paramètres des filtres de cartographie sous-marine et en observer les effets. Côté mécanique et électrique, le sous-marin a été réassemblé avec succès. Tout fonctionne bien… mais mentionnons la petite sueur froide qu’a eu…
