Test Report – Test 1

By | Test Report | No Comments

First test of the competition. The plan was to do the gate in order to put the qualifications behind us. 2 minutes before leaving for the test, two thrusters stopped working (Welcome to Robosub just like Jay said). We are going to figure something out, we had a test pool yesterday and we didn’t change the Software or the Electrical, we’re gonna see… At first, we had problems receiving the data from the pinger. But the problem was quickly solved. We had a very good signal and the noise from the thrusters are merely impacting the ping. However, the phase…

Premier test de la compétition. Le plan était de faire la gate pour en finir avec les qualif. 2 minutes avant d’aller au test, deux moteurs on cessé de fonctionner (bienvenue à Robosub comme dis Jay). On va trouver la raison. On a testé en piscine hier et rien n’a changé côté l’élé ou log, on va voir. Au début on a eu des problèmes à entendre les pings, mais le problème s’est rapidement résolu. Les données sont de bonne qualité et le bruit des moteurs est assez faible par rapport au pinger. Par contre, le déphasage qu’on calcule n’est pas…

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…
