 Excuse me. The mic's on there. Just to check your voice if it's not working. Please just pulse switch. Thanks. Good afternoon everyone. Okay, so today we're just two students who have built a submarine. I'm Daniel. This is Michael. Have fun reading the descriptions. Okay, so why do we build this submarine in the first place? Is it for the greater good of humanity? Is it for the joy of discovery? No. We were signed up by a friend. And I guess in the end we found it pretty interesting and cool. So yeah, maybe it's still cool to do a drill, maybe it's not. Who knows? But what's so difficult about building AOBs, right? Isn't it just an underwater UAV that you have to change the name because otherwise it's too similar? No, it's not. Waterproofing is quite difficult. You can just seal everything in silicone, use gaskets. The thing is the sensors and trusters that you need to clean the water because that's the medium and you need to instruct with the medium, right? And reliable efficient pastures are difficult. And another thing is that buoyancy is surprisingly difficult to estimate. Sure, you have this fancy equation which is very fancy, but as I've been building a drone, the problem is not about how heavy it is or how bulky it is. It's about finding the center of gravity or the center of buoyancy in this case. So I don't know how many of you have built a drone here, how many of you have no idea. But with a drone, all you have to do is balance it on something and see where gravity takes it. Thinking about the submarine is that the water, the buoyancy of the thing, especially when it's filled up with water for air, like when we use a sealed hull. The buoyancy is always gravity. So you have to waterproof it, drop it in the water and then balance it from there, which is very hard, especially if you don't have a giant body of water. So yeah, that's it, we ended up unbalanced. And the proof, case in point, look at this. Yeah, not very balanced at all. Yeah, so that's because you have many design issues from the experience. Yeah, I think drones is pretty common, but some of these are first time to cross at least. Center of gravity or center, exposed cables. And what's actually demonstration? Look at this. Guess what happens? I think it electrolyzes, like the one of the right tests, like solid deposits from electrolytes in the water, very fine. And that's the programming thing. Image recognition doesn't work. I'll fix that. And so, where are we now? So this is a new movie that goes to the ground up. Seeing that the whole... Can you guys give me the mic mic? Okay, so people go to the ground up after realizing that the whole movie was not exactly close to the show. It couldn't turn around. It had issues in terms of its morbidity. So do you expect that to be new? Most of the movie is actually industrial heroes who just have seen it and certainly have done that, right? This is great for a wide group of operations in the ocean because you're not feeling like you've done anything. What happens to you? What takes down people? Tries out things such as coral? What do you maneuver with the deal? So, thinking like an underwater pop-up, they decide to make these wreckage rushers. As you can see, they're actually able to tilt them. This allows us to achieve like this. It allows us to achieve drone-like maneuverability. But because water is fun to discuss, we have to be able to make it into any direction we want. That's cool because I see this. So, as I said, the pattern would be the underwater pop-up. But today, we want to present about why we... Sorry, we're not going to present on the technical issues, but rather why we build this up first, please. So, first off, this was a target console because of our great mentors and access to this for design studio. The way access to design studio and engineering processes actually allows us to link them and collaborate with many other beauty makers that will do these kinds of crazy projects. This, for example, as you can see in the photo, is us having the kind of stars get the hot chocolate melted by a unique water system melted by one of our spheres. But, it's fun to discuss. Okay, so... But, as I said, we work hard on this indeed. So, because we're students, we have limited time. This means that after we finish our homework, we usually have to sail at night to test. And, of course, at the end of the day, as I'll show you later, we actually have to test by this... bring near the pod with a... sorry, bring near the field, and instead of the pod, we have to use a large plastic box for a thing of UV. This was taken at 11 p.m. at night because we really, really had no time. And, as you can see here, sometimes you get picked up a lot because you work way too late. This is Daniel applying heat shrink in the stairwell because it was too windy upstairs. So, as you can see, it should be working the same in the lab. Sometimes, our interest is simply... cannot be helped by it. So, again, we couldn't test it at the pod. We had the pod, we had the pool, we had to test in school in near the field. Surprisingly, it worked out quite well. Although, I don't know if you wish for this. It is not so much because our product is for a new sherry. It requires high-tech solutions, but rather because I want to make a point. The point being, that maybe it's not simply working a lab all day and coming up with a final product. It's the journey. Make your solid interest and make it can be done anywhere at any time. As you solve, you are on the field, somewhere with no tools, and you might as well find out what's out there, when there's only iron, and get everything done in the middle of the night, on a small night. So, as long as you're in fashion, and as long as you're in time, making it can be done. We have two announced 18-year-olds, and we've done something that most of you need students have not done. So, with that, I would like to thank you for just listening to this quick presentation. Please stop by our booth downstairs if you'd like to know the more technical ideas of this. And if we have a bit of time, sorry, can you show me how? Two minutes. Okay. Is there any questions? I can help you. One, two. Nope. Have fun. Okay. So, as you mentioned earlier, this was actually designed for SQDC. This is for all of us underwater people. You need a lot of students whereby you have four big tasks. Number one, to deploy, walk out of bed. Number two, image recognition. It comes from two parts. You have to work with a green ball to the left and a red ball to the right in that exact orientation. The second part of image recognition is to actually find the color of the object in the scope. Deposit the ball in. Before it deposits the red ball to the right of the point. Finally, to treat the ball, we have to pick up the ball from... Coup d'autonomous. Coup d'autonomous. Yeah, so basically, we have to also collect the ball that it deposits earlier on. And the big catch of this is that it is completely non-coup d'autonomous. So that means we have to have all the sensors in the background. Suddenly, you didn't actually get it done in time and you're a part of the shooting project, so we want exactly all the sensors. But nonetheless, we found it quite interesting, considering it's a unique level of competition working at us and around GC-level students. And we want to see all the... what suits around the world because it's a competition of Russia and China working out.
