 Such I prepare some slides, but unbelievably I couldn't get them off my tablet like no way I tried allowed me to get that file off Which is unfortunate? Well, that's well, I've still got it So if anyone wants to see my my scribbled drawings on my tablet then that might help you, but I'll see what I can find on the web So I've just graduated. I'm also fun employed completing the triple threat there of fun employed people So what I did for my my master's project in my engineering degree was build a human powered submarine Which I'm going to tell you about for a bit So this is a it's a team effort. It wasn't just me There's a there's a beautiful picture of us There you got me sort of like hiding in the background there So what you're seeing there is the the chassis here out of box section this bit here I'll a minion box section we made a rather unconventional submarine to be honest because what you might sort of I miss something. Oh search history was that Oops So, all right, okay So moving on. Yeah, what you'd expect a submarine to look like is something like that. Yeah, sort of sleek slim pointy These guys are at the competition with us this year. They were fucking legendary. They're Canadian and that thing was wicked fast There's actually two guys in that sub. It's really long. It's really cramped one guys head is right next to the shaft So it's sort of like this in the in the arse end of the nightmare. Anyway, ours did not look like that I was at work uni and that's like literally right in the middle of the country. No sea anywhere nearby No marine expertise. None of us knew what we were doing and it was the first year that work had run the project So We just didn't know what we were doing essentially and we were competing with a load of guys that did why are there No pictures of us this sucks All right, I'll find out Facebook So anyway, we were We were building this submarine with with no idea what we were doing. Can we not search on Facebook without logging in? There we go Yeah That's not even the Facebook page. Okay, so yeah, we built a submarine It's pedal powered. There's a there's a dude in it. It goes underwater and it's it's described as a flooded hull So it's not sealed. It's not pressured and this is what we made You'll notice that doesn't look anything like the the nice sleek sort of cigar shape thing. I showed you before We had this key realization I'd like to take some credit for it. I'm pretty sure it was me I don't remember exactly, but I'm gonna take credit for it It's not a pressure vessel So it doesn't need to be round because we've not got to distribute this this pressure evenly So what we did you can see here. We've got this sort of trapezoidal cross section coming down here across the bottom that was to like accommodate the pilot's position he sort of So he's got his hands on some controls down here face here looking out of all these nice big pretty windows His bum's up here and there's some pedals around the back So yeah with this trapezoidal cross section what it actually allowed us to do is save a lot of time money effort Versus the these guys who have a composite layup So they build a massive mold and then fill it with glass fiber and whatnot huge hassle All we did was weld some aluminium box section together and then slap some panels on it Super easy really cheap really modular extensible, you know if you need to do anything to it We were literally just taking a drill to it putting a new hole in cable tie through the hole done easy peasy So our first entry into this competition We actually did really well what you're seeing here is the awards room at The kinetic base down near Gosport, which is where the the competition was held So that's us in the awards room One of only two subs exhibited in there out of 12 competitors on our first try So we were pretty happy with that. We did really well. We came fourth overall out of 12 If only you have to wait for later for that. Yeah, so we came fourth overall out of 12 And the main reason for that was basically we we were the slowest team out of any that actually finished the race The other ones just didn't finish it so there were three good subs they went around the course they did it quickly and Then there was ours went around the course. We literally took about four times as long as anybody else They were doing it in 90 seconds or so We did it in about eight minutes something mental like that So ours was hella slow. It was it was full of problems. There were multiple design flaws. There should be a nice Nice picture on here somewhere maybe not so the course you have a sort of a straight line down this giant swimming pool imagine sort of Like an Olympic swimming pool, but twice the length in every direction. Is that remaining? One minute remaining. Wow So, yeah Sort of twice the size of an Olympic swimming pool in every direction you go down it You go around the end and then you come back through a slalom And yeah, we did quite a while. We ended up with an award for so-called dramatic performance nicknamed the Oscar Because ours was just so ridiculous compared to all the competition we got Nick we got nicknamed the underwater Land Rover But the thing is we did well because we we stuck to some principles We said just make it work and then make it work better You got to get something working first and having something that actually worked was really key in this it was ugly You know, it just looked horrible it everyone thought it was an absolute joke when we turned up But we ended up coming forth and we were pretty happy with that. We didn't know what we're doing But in the end we actually did really well So running low on time any questions Go ahead Well, that wasn't for us to judge really I agree. It's it's a bit of a silly thing the literally the only use I can think for it is drug smuggling I was unable to think of any other use for it and we tried you know We were down there on the South Coast for a couple of weeks for this competition over that whole time I didn't hear anybody suggest a legitimate use So yeah, I am I drew a nice little diagram, but obviously there's a like Air tank in there for the diver. We've got Various sort of like essentially balloons which you can fill with air to control That's the word I know what I'm talking about. Thank you Right questions. Yeah Well, it's because of the way the scoring was structured So you have to you have to finish the race without scoring any penalties for it to be counted So even though we took eight minutes or so to get around we did it without any penalties and none of the others Well, most of them didn't even get around at all. They're all sorts of errors Like there was one who had a biomimetic sort of flapping fins like that which looked gorgeous, but just didn't work Like not even in the slightest others had like one one pilot kept repeatedly having panic attacks in the sub and nobody realized And he wasn't admitting so every time he got in and then he was just like no, it's not working It's not working But it was actually just it was a having a panic attack and they didn't realize this until two days before the end Putting your pilot in new pilot didn't know what they were doing because I hadn't practiced so didn't work All sorts of errors like that Ours was huge. There was plenty of space our pilot was Apparently he's really bad at driving games Which we we only found out about halfway through the competition. So perhaps that was why he couldn't really steer very well But he was at least an experienced diver so no panic attacks So yeah, that was why that was why most of them cocked it up so massively Just you know many many failure modes and they were hitting all of them anything else Lovely. Okay. Well, if anyone's got any further questions or wants to see my little scribbling of the submarine come and talk to me My name is rich by the way. Thanks to everyone for coming to the Latin talks
