@@CPSdrone nice 😎stick to the plan 👽
Adding a rear camera would allow for constant monitoring of the tether which might help to avoid tangling it.
How about low frequency teeny cameras with a 180 degree lens, attached to the cable at points?
This way you can keep cost low, and resolution high, as a camera that takes one picture every few seconds is cheaper than a video camera.
Granted you would want the camera photo outputs attached to a different fibre-optic cable, wrapped around the first one.
This is just an idea, that could be worked into a much better solution if thought through, what do you think?
@@minipac2Cable is fiber optic! There is no power!
Stitching the video of two opposing 180 degrees cameras into a 360 degrees video would be super cool.
And put some sort of cage on the motors
@@minipac2 I think putting cameras along the entire fiber line would just make more points for the line to get snagged.
My brothers, use a steel rope next to the optic cable. Connect them with heat shrinking sleeves every one meter to prevent such entaglements. Keep up the great work!!
it would also help reinforce the tether for pulling in an emergency
Brilliant!
Connect them every 1 metre? Ha great, you've now just made a cable with hundreds of loops on it that can catch anywhere. 🤦
@@TimmmmCam lol exactly...
If you're going that far you may as well include a power cable
Need a mesh or netting over the propellers to prevent things from entering them.
Yep, we'll do that
I came here to don my Professor 2020 Hindsight hat and say the same thing.
Or try to use compressed air to clean the propellers
@@KASH-CHEN how would that work underwater? like where are they getting the air

HACKSMITH, USE TO WATCH YOU WHEN I WAS YOUNGER AND STILL DO
As someone who works with fiber, the fact it started working again after being sucked and torn open in the propeller is insane which led to the retrieval. You're incredibly lucky, fiber in that state is very rare to function and probably have countless cracks
to stop tanglement in thruster, you should try using honeycomb thruster guards. It significantly reduces tangling
as well as might add somewhat a bit of thrust due to having a linear thrust output if you make i 1cm (1/2 inch) thick instead of creating turbulence
Also toroidal propellers
@@Mark-uk8wz toridal props that are good arent really worth the cost.
@@Mark-uk8wz those cost like 20k USD each, are you insane ?
@@DrakyHRT it is diy submarine with printed parts yes? how would it cost 20k to print your own parts lol
I randomly stumbled on this video, and watching this makes me realize what an incredible time this is for creativity. The tools we have for innovation is mind boggling. The world literally becomes a sort of playground. I get that feeling when producing music, I'm sure these engineers get that same feeling.
All thanks to 3D printing, 3D printing changed everything
I’m pretty sure humans started to feel like this since we first invented the wheel
I know right? There’s another college student building a literal flying car in his garage… that’s where the world is now.
No joke, in another decade or two we will have kids building jetpacks and robot companions for fun.
We already have teens making complex robotics, autonomous vehicles, racing drones, and so much more and it’s so “easy” now with access to the internet, 3D printers, affordable machining and fabrication services… etc. whatever you can’t make yourself you can basically order for pretty cheap.
It gives me hope in a world that’s so dark and depressing that there’s at least some good coming in the form of curious and adventurous young people!
Thank you for giving the US distance in Furlong, could not help myself and was laughing 10 minutes straight
Impressive that the sub-drone even moved after all the stuff tangled in propellers.
You missed the opportunity to use a logitec controller
For the memes!

For the home builder, fiberoptic is really expensive and breaks easily. If you watch the big work-class ROV teams, they've got a huge large-diameter drum they wind it on and off, to bend it as little as possible. I use RG59 coax, with an ethernet-over-coax adapter at both ends. This gives me good connection over as much as 1300m. I also put a stripped-down security system NVR in the ROV, allowing me to have real-time views from 8 cameras.
I also put 'hardware cloth', 6.5mm square galvanized mesh, formed into a cone, over both sides of my thruster ducts, to prevent the injestion of foreign objects. Next time it would be a good idea to bring a folding table and some chairs...LoL.
I keep thinking of more stuff. Making the ROV positively buoyant means when you get close to debris, the water stream is jetting up, minimizing kicking up clouds of particles. Keep the lights as far away from the camera as possible to reduce backscatter from all the fine particles suspended in the water. Putting a hook in front could help you untangle or retrieve things. Servos can be filled with mineral oil, their potentiometers replaced with magnetic ones, to use outside the ROV. Putting the camera in a small WTC so you can pan and tilt with a headtracker makes it easier to maintain situational awareness. I made my lights track with my camera so I'm never blinded.
The size of the tether and the drum has nothing to do with bend restriction as we have much tighter bends inside the vehicles.
The work-class ROVs run off of 3KV and quite a few amps which requires a substantial cross section of the cables. Add kevlar armour and several layers of insulation to that and you end up with a hefty cable. The FO parts of the tether is usually just a 3mm stainless pipe containing around 10 individual fibres.
This man ROV's
Back in the old days, Ethernet run over Coax, either thick-ethernet or thin-ethernet. If i dont missremember the thin one was RG58. I have had plenty of ethernet adapters with coax, the possitive thing was that you did'nt need to use a hub, The dowside was that it needed to be terminated, and if it had some error inbetweeen the whole segment went down.
Try to add a geiger counter or a scintillator (which is better in this case) on the next version of the submarine, to measure the radiation level under there. Sorry if I said something wrong, I'm not a native English speaker :)
The water would probably block all the radiation though :(
I also had that thought and checked the comments first. I think it would still pick up in the water or at least let you know if the water is contaminated.
Your English is amazing don't worry, you said nothing wrong
Regarding the folks suggesting you oil fill the enclosure. If you want to pressure compensate, or simply pressure balance an enclosure, it's not as simple as just filling the enclosure with oil. You'll need to add a compliant bladder or spring assisted compensator to account for any air bubbles that may get trapped while oil filling. If you go the route of using a compensator, you get the added advantage that if a leak should develop, oil will leak out instead of water leaking in. If you remotely monitor your oil level, this can warn you that something is wrong and give you time to respond. What's often the most difficult challenge of oil filling enclosures is that all the components you have within the enclosure must also be pressure tolerant. Anything that's soft or contains an air space isn't suitable for an oil filled pressure housing since the oil will communicate the exterior pressure to all the components inside. This can include complex things like your camera, but also some simpler discrete components like crystal oscillators, electrolytic capacitors, and much more. component selection at the board level becomes a very important consideration when deciding whether or not to oil fill for pressure balancing or compensation. In many cases (especially when cameras are involved), it's more practical to use a one-atmosphere pressure housing.
would encapsulation assist with component level pressure resilience?
@@amandahugankiss4110 Good suggestion, however, that's also a solution best used with pressure tolerant components. Just like with oil, the epoxy or urethane used for potting will still communicate the exterior pressure to the components within. When encapsulating or potting, thermal management considerations must be taken into account as well. Oil will naturally convect heat away from hot components but a solid material won't. You can get thermally conductive epoxies, but they won't work as well as oil so you'll often have to pot components onto a heatsink and then leave one side of the heatsink exposed.
@@finnigan16 You could embed heat pipes into the epoxy potting to help with some of that.
@@dustinbrueggemann1875 Good thinking, but you'll still have a problem: Heat pipes themselves aren't pressure tolerant components since they're filled with a substance that needs to transition between a liquid and gaseous state in order to work.
A similar idea that would be pressure tolerant is using pipes to liquid cool the components. however, the plumbing for heat pipes and liquid cooling systems still typically require a heat sink to interface with the component they're intended to cool. It's easier to just mill a custom heatsink that will accept your board and the potting compound on one side, and interface with the cooling medium on the other.
I have seen heat pipes used in subsea robotics, but only in atmospheric pressure vessels where they're protected from the external pressure.
Submerge it all in mineral oil.
"it swims violently" killed me
What an adventure, I was afraid to see this being lost but it turned well, it so amazing that the fiber optic cable still worked. As a diver I can recommend you have a secondary rescue line for the drone, usually that would be mounted on a buoy in order to see it from the surface and slow release the line to avoid being tangle, and of course have a hard long line to pull it back to the top
Watching you guys handle the motor and the assembled sub in the test tank… glad you still got all your fingers!
yeah thought the same
Panowie wielki ,wielki szacun.Emocje niesamowite tak jak praca włożona w ten projekt.
Pozdrawiam serdecznie i oczywiście czekamy na część drugą 👍
Now this video is the reason why we love our engineering nerds, this is an awesome project. Hyped for the next adventure.
To avoid tangling, you can also add floating buoy to keep cable in the center and under tension.
I'm not shure I'm picturing this right in my head ... but wouldn't any bulb, baloon or protrusion that's fixed to the tether be an additional point that could get stuck or wedged? Or do you mean something like a cable with slightly more buoyancy that would keep its tension and any surplus length would float at the top?
Or maybe we can do something else like adding a small metal pipe like 2 feet, attached to the submerine and the cable is passed through the pipe, to keep the loose cable 2 feet away.
@@HarshSharma-up5nm to avoid strain on the cable on the end of the pipe, you can add rubber flexings
@@twelvelives5378👍👍yeah

This was so nerve wracking to watch, keep up the good work. So excited to see the next iteration and improvements
Nice video!
I do suggest checking the dB/dBm values on the fiber optic cable since it got stuck, it would be a shame if it lost connection on the third attempt.
packet loss monitor probably an idea too for higher layers. I think that is what was messing up the video.
Perhaps bundle a fine Teflon/kevlar line to the fibre-optics, so if it fails eletrically, you can reel it in with the strength-tether.
@@zyeborm I think it is probably the fibre optic cable wrapped around the propellers and damaged that was messing up the video.
@@WhiteWolf65 there is no electric current in fibre optic cable so it cannot fail electrically
@@szlomobronsztajn3115 If the Drone fails electrically, genius. You going to try to reel a dead drone in with a fibre-optic cable? NOPE.
The fact the drone worked at all, with that much tangling, is amazing
Might need a distance based tensioner?
So glad you got the drone back. Fingers crossed for the next go!
ah yes the thing covered in uranium particles
Super dron i fajny film. Takiego polskiego youtube’a to można ciągle oglądać. Powodzenia z projektami.
Dzien kuje, first of all. For talking english most of the time for the benefit of us. Appreciate that a lot. And awesome project indeed. looking forward to the next video!
So awesome to see Polish innovation and grit. I am proud to be Polish ❤❤❤
you should add a sort of mesh tube around the fibre, to prevent it from being worn against obstacles
😮
You guys should start a small submarine racing club… do some events at local pools and lakes, maybe drop a few small prizes to the bottom and challenge people to build a sub and come and find it.
That would be really cool and a great opportunity to share this hobby with younger kids, especially if you made a simpler design that could be sold as a kit that parents can buy and assemble with their kids to use in a pool or whatever.
Imagine being a little kid with a new 3D printer for Christmas and mom also got you a kit to build a friggin submarine! How cool would that be!?
I’m excited to see whatever you guys continue to do in this field and I love how you share it with others. I’m definitely glad I subscribed!
You should add multiple 180 degree cameras to hopefully be able to see what's happening around the drone if you end up getting tangled in places.
You all are amazing! I never would have figured you would have such an exciting video about a homemade drone! Keep at it!
Good job! Your close to getting to the lost river! 👻
subnautica reference?
@@KarlDRG yeh
Was searching for someone from Subnautica in comments lol
Congrats for the 10M+ channel views! Keep building cool stuff.
That's why you need redundancy. Double the cable, double the camera, emergency power. Program to swim up in case connection is lost. Additionally, you can add mesh cone on the back of the drone, to push away things and prevent the drone from getting stuck, while letting water through to keep the flow from the motors.
Double the cables also means double the oppurtunity for them to get stuck.
@@coffeefish4743 What I mean it's not two separate cables, but two cables woven together, so in case something damages the cable, there would be a second channel left.
@@AllExistence this wourldnt change a lot, fiber optic cables work until they are compleatly ripped apart so two cables woven together wourldnt change that
@@TotallyNoAim Well, yeah, that's only true for normal copper wires.
@@AllExistence uhm. No. Copper wires fail as soon as one copper string gets cut or two copper strings get shortet

Kidding aside, this was a super cool project and I enjoyed the whole vid. Great work boys! Cheers from the US
Once you have a drone that can make it to the bottom, you should take it to the ocean
Yes. Stop torturing it. Set it free to the ocean.
Ocean is salt water, which causes additional problems, the buoyancy is different and the electric motors can corrode quickly
@@bastienx8 then how bout a really deep lake?
@@bananapeel2684 a deep lake would be just like this 200+ meters mine, but with less obstacles
You guys are insane, thank you so much for the awesome video AND the free training course! I am super excited about this
you deserve a million subscribers keep going!!
Very nice graphics/animation to explain the tangle. Nice sub too.
You have a TON of optimazation to do regards to traversing terrain. Design of the shell, sensors, control etc can all be added/improved. But you have made an impressive step !
Because there are no pressure sensitive hardware, you can put a can of pressurized air inside the submarine with a remote controller valve, and a valve that automatically releases air when the pressure outside the submarine is lower than inside.
It's basically to pressurize the inside to keep everything in place and give your material less difficulty keeping out the water when you go down. When you go up the pressure is release to prevent it from exploding.
Seems like you need to add manipulators to help move stuff out of the way...and perhaps a backup camera that can see the body of the sub.
like a third person camera that's attached to the tether 2m behind the sub. Could be cool, could be helpful, or could be another object that can get caught on something.
@@Culpride yeah, i guess its the first thing getting caught on something, haha 😆
Gratulacje i powodzenia przy kolejnym podejściu
I think you should make a redundant communication cable, so if a cable broke/snapped, you can still recover the drone
i think ultrasonic communication as a secondary might work decently
A few suggestions.
First, don't use your communication cable as your physical retrieval cable. Using a metal cable will ensure that you don't potentially damage your fiber optic cable.
Second, guards over your props to prevent debris from getting entangled.
Then the last thing I would recommend, add two pieces of tech. The first, a simple device attached to your reels like a buoy that keeps tension and prevents excess cable from being given. This would drastically help reduce any chances of your own cables getting caught in the props. Also, you can write a program that records your inputs and creates a virtual path for the drone. What this will allow you to do is create a program for the drone that will let it retrace it's steps exactly. The benefit behind this is that you can allow the drone to be able to calculate how to move along a path even without all it's functioning props.
might I suggest some sort of Carry-on handle and or wheels so it can be moved more easily?
You should add an emergency blast tank blow procedure, in case the drone loses connection since it's an expensive drone. you can use what divers carry on their wrists to float in case of emergency as guidance. just pitching an idea :), good luck.
Here is a dumb idea - can this be made to be a wireless craft? I do not know how much water attenuates radio signals but what if you lowered a transmitter/receiver designed like a plum bob - basically a torpedo shape that lowers only by gravity. Then it could be kept in close proximity to the submarine craft so that it might be able to operate more freely. Anyways thanks for the awesome video, super well done!
Pressure and water. Small waves

Using furlongs for the US measurement is ultimate BM and I like it.
The best sub drone build by polish students.. Zajebisty.. !! Greeting from a turk ..from germany. 'Pozdro !
7:14 is that a nuke
The controller being used reminds me of something a bunch of rich people did
You could develop some kind of sonic transmission. It should work very well in isolated mine filled with water. Just two sets of waterproof microphones and speakers - one on the submarine and one on the controller.
Obviously it will not give you good video but should be enough to get submarine back up in emergency like that.
Great idea!
it wont give you any connectivity at all as soon the motors start. the noise chops up any usable signal you might have had.
@@swfreeD Isnt it matter of frequency? Motors operate at rather fixed rpm and rest of all the noise is going to be relatively high frequency.
Anyway issues with idea is mostly baudrate. I do not imagine having much of use with something up to (generously) 1 kbps
This is one of the coolest things ive seen on youtube!! Fair play to you guys!!
It might help with the tether problems to use some sort of sprung coil so it always keeps light tension on the cable preventing it from randomly floating around and getting tangled, maybe make the drone slightly less buoyant to compensate the pulling force on the tether, also a backup camera to look straight back would help when retrieving the sub without needing to turn it around and maneuver too much, lowering the chance of tangling even further.
Incredible mission, well done chaps
1:34 You would have to find an oil that is both non-conductive, and is as non-compressible as water. Water doesn’t compress very well, and if you have an oil that does, the water pressure will compress it into a smaller space and create leaks. Or, if the goal is to negate the pressure on the hull, it will allow the hull to buckle anyway. So having a non-compressible fluid is absolutely critical for preventing implosion. You’ll have to get a fluid with a compressibility as close to water as you can get.
As for the interference with the cameras, it is a Uranium mine, so there’s a possibility of some radioactivity playing with the electronics.
It's nice seeing fellow polish guys doing this
Polak potrafi wszystko, bez limitu. Jeszcze znajdzie duzo miejsca zeby poleprzyc.
Pozdro!! I tak dalej.
Wow - I am 1000% impressed by you guys!
If you could put some sort of tripod over top with a pulley on it you could keep the line going straight down the shaft. Then you need to keep pressure applied to that line. You might be fighting that a tiny bit all the way down but it would also mean it wouldnt be able to get tangled.
Add some mesh to the propellers, might stop stuff from getting tangled in them
I would recommend replacing the fiber tether with something like an FTTH drop cable. These have two fibers sandwiched between two fiberglass wires. Then the whole thing is reinforced with another steel wire. This type of fiber cable isn't immune to tangling but it tends to want to stay straight because of the metal wire. It also resists bending and can be pulled pretty hard thanks to the three wires embedded in it. The soft kevlar reinforced wire you're using tangles very easily and it's light and soft enough to be sucked in by the propellers.
great video guys, pls do more of this with this drone, this was some of the coolest footage I've seen in a long time. Plus the editing is very well done, I ccoudnt guess if you were gonna get it out or not
I love the lego gold block building sounds😂🤙🏽
You really managed to capture the thrill in engineering and exploration! Gonna show that to my kids 😊
adding something like a thin webbing over the props would help prevent future wire entanglement issues, probably the easiest fix you can do just by adding a little bit without any major changes.
I think "swims violently" is now among my favorite phrases
Great video! Maybe some metal grills over the prop intakes?
Dobrą robotę robicie chłopaki. Powodzonka z następnymi projektami
Definitely add a rear camera. Maybe some kind of grabber to remove obstacles. And if it was in between size then you could still make the housing strong enough for depth plus restricted operating environments?
that's incredible! but an idea, put a net maybe like a 3d printed one and cover the back and front of the motors, shouldn't lower thrust much but it will protect both motors and the optic wire from getting random stuff tangled in there
You can add some emergency balloons that can help get the dron up if you lose connection. It could work by inflating the ballon when the submarine detects signal loss
Too much pressure.
congrates on ur achievement guyz..would be great if attach a clamp for picking objects😊
I could see so many flows with this design...
You know this was stressful because he hit 69 meters and didn’t even pause to say “nice!”… this is truly serious business here.
One idea could be to incorporate some kind of cutting mechanism near the rope, allowing it to automatically sever the rope if it gets stuck underwater.
You should add a bouy for the fiber optic cable to prevent tangling and add a camera to that for kind of a third person view. That would give some really immersive shots and probably helps navigating because you see the whole sub with suroundings.
always use a mesh. even if it restricts flowrate, use a mesh. I do alot of sub exploring in terribly overpoluted lakes and theres weeds, line and plastic of sorts everywhere. I gluegunned a mesh on the in and out of my props and that solved all my issues. if movement feels slow, I just push whatever is stuck in the mesh out with a couple seconds of thrust.
For exploring the side tunnels, perhaps you could add a spool of cable to the drone as well to lay down as it goes instead of pulling the surface cable over sharp rocks and stuff.
Adding a steel cable along side the fiber, strong enough that you can yank on it if the drone gets stuck or caught would be a good idea for that use case, and it would probably need a fail-closed ratchet on the cable drum to lock the drum from rotating if power or data is lost so that you can yank on it without just pulling more cable out of the drum instead of yanking the drone.
Torpedoes use a similar mechanism for their wire guidance system to play out fiber behind them instead of pulling it from the sub, to avoid breaks or tangles.
so what you need next time is a propeller screen guard and a crane to center the fiber wire adding little bit of pressure so it wont slack. Also add like a spring type tube that elevates the fiber wire above the drone.
AMAZING JOB. What a submarine drone
lol, now the next thing you need to add on to it is a manipulate hand, just in case you get snagged again, also some anti-snag protective propeller covers (screens), to prevent shit getting sucked up and wrapped up into the prop motors.
Great work! Amazing, really. Very inspirational. Keep it up 👏
