Robosub 2016 – Day 6: The Validation

By | Competition | No Comments

Hi! Today was a big day. There was a lot of sails to set (see what we did there) but we managed to pull through. We fixed all the problems we had yesterday (malfunction in timeouts and weird behaviors) during the night and the morning. We had 3 tests. The first one was spent getting hydrophones data. We realize we did not have reliable settings for 35 kHz. We were however able to locate the pigner at 30 kHz in the other ring. Alexi spent the day improving the firmware and adding debug steps. The next state was for mapping….

Robosub 2016 – Jour 6: La Validation

By | Competition | No Comments

Aujourd’hui a été une grosse journée pour l’équipe SONIA.   Nous avons réussi à régler les problèmes de la veille au courant de la nuit et du matin. Il va sans dire que la transition nuit-matin a été plutôt brève. De toute façon, comme on dit, dormir, c’est pour les faibles. Nous aimerions remercier Monster™ pour nous avoir si bien supporté. Nous avons eu 3 tests aujourd’hui. Le premier a été utilisé pour obtenir des données sur les hydrophones. Cela nous a permis de réaliser que nos paramètres pour la fréquence de 35 kHz n’étaient fiables. Par contre, nous avons été capables de localiser le pinger…

Robosub 2016 – Day 5: In the middle of the challenge

By | Competition | No Comments

Today definitely was a long day. We arrived on to the competition site around 5h40 am and we left around 7h15 pm. The results of the fury of the team start to appear, but the final runs are coming fast. Some of the less experimented team begin to test, so we asked for more test time. The test period starts spacing from each other. The advantage that we have compared to them is that we start the every test ready. The inconvenience with this situation is that we will eventually have only 3 test of 30 min per days. That…

Robosub 2016 – Jour 5: En plein cœur du défi

By | Competition | No Comments

Aujourd’hui a définitivement été une longue journée. Nous sommes arrivés sur le site à 5 :40 et nous en sommes repartis à 19 :15. Le résultat de l’acharnement de l’équipe commence à paraître, mais les finales arrivent rapidement. Les équipent moins expérimentées commencent à pouvoir aller à l’eau, donc à demander plus de temps de test. Les périodes de test commencent à s’espacer. L’avantage est que l’on arrive mieux préparés à ceux-ci. Le désavantage est que l’on va potentiellement devoir se contenter de 3 tests de 30 minutes par jours. C’est très peu pour la quantité de code à tester, mais l’expérience…

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…
