Yesterday was the second and last semi-finals run for our team to qualify for the finals. We had to complete more obstacles to be sure to qualify. We managed to grab a test at 11h40 to make sure our settings we’re working.
At 11h40, we entered the water. The first two tries didn’t work, so we had to get back to the deck and modify our mapping of the zones. After, we managed to navigate to the pinger zone, but our navigation couldn’t go straight forward due do the distance of the zone. It followed a curve path, passing over the deeper part of the pool, resulting in faulty readings from our navigation and pinger sensors. We decided to manually adjusted the position and try the pinger mission. We were able to surface in the correct octagon.
After this test, we decided that the most secure way to navigate to the pinger was to follow a zones path using all the other obstacles. We adjusted our settings and we then waited for our qualification run at 14h00.
We we’re in the water at exactly 14h00 for our run. The vehicle quickly passed through the gate, but a small offset caused the vehicle to head to the wall. We quickly killed it and brought it back to the deck. We modified our zones mapping and started over again. The vehicle passed through the gate again, hit the RGB buoy on the right color, and then navigated to the pinger zone while following the new path that we worked on. Everything went exactly as we hoped and the vehicle surfaced into the correct octagon after the longest three minutes in the world.
The mission ended and we ran out of time. We are extremely proud of our qualification run and we are getting ready for the finals!
