RoboSub 2019 – Day 2

Yesterday morning, one of the ethernet wires in our recently soldered tether snapped, which meant the Electrical Team needed to re-splice the cable. 

The rest of us had it a little easier. We had no food items whatsoever, so it was time to go grocery shopping. We drove to Target and stood there all googly-eyed like the good old Canadians we are. All of us stood out like a sore thumb with our beautiful red team shirts. The team purchased everything from cereal to shaving cream to paper towels. Poor Nicholas had to make do with his three-ingredient tasteless granola bars. 

After we got back from the grocery store, the Electrical Team had fixed up the tether! We all took a moment of silence to rejoice at this fact. A new router was set up and the motor test was passed. Then, the Mechanical Team efficiently took off the camera mount! To celebrate our efforts, we all took a little trip to In-n-Out and flaunted our team shirts once again. Everyone was now full and happy. 

 

At 5 pm, we went down for Orientation. Then, we grabbed delicious burritos from Chipotle to keep us awake for our pool test until 2 in the morning. 

To keep us occupied for the next couple of hours, we started making the world’s best robotic memes. Jon found the Polish Team’s robot design, which became the focus of all our creations. We then sent our masterpiece to the Polish Team, who sent us their creation back.

         

Well done to the Polish Team, but we all know our meme out-memed theirs. 

The rest of the evening was spent checking and double-checking that the robot was ready to go in the water as we anxiously waited for the clock to turn 10. Taking off the camera mount turned out to be a really good idea, as the robot was even more stable now compared to the final days before shipping it. We had a few challenges, including pitching issues caused by the motor controllers being subtly untuned and problems with the initialization scripts for the sonar system, which seems to freeze the sonar system. We hope to fix these issues by tomorrow night. Overall though, with torpedoes having fired successfully, a balanced robot, and drained batteries, the night crew was able to head to bed happy.
