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?
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!!
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
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.
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!
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.
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.
Your a wonderful person to share knowledge . I must say. It’s probably why your blessed so much. I wish I had good friends with much energy like your friends and you
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
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.
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.

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
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.
@@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.
@@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.
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.
@@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.

Thank you for adding the measurements in furlongs. I was just telling the missus that I wished more people used furlongs. /s Kidding aside, this was a super cool project and I enjoyed the whole vid. Great work boys! Cheers from the US
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 :)
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.
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!
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.
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!
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.
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.
@@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
Fiberoptic cable is resilient as hell. As long as it isn’t cut it'll work, barely. The loss in signal strength will be awful but data can still get through.
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 !
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.
I saw the potential problem with the cable before it happened. Good job at staying calm while untangling it. With all the protrusions and exposed props it is amazing you made it that far. I was impressed with the power of all those motors and the piloting of the drone. Great video. Subbed.
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.
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.
Might be a good idea to make the drone wireless, specifically Im thinking on keeping the fiber optic cable but instead of connecting to the drone you connect it to a wireless unit that connects to another wireless unit on the drone. You could then attatch the fiber optic cable to the drone using something strong like fishing line and setup a release mechanism that lets you remove the fiber optic line from the tether and easily pull it out while still being connected to the drone.
@@braden6973 Maybe a light based solution. Using high brightness led to strobe the data. Using two different colours and a colour filter on the light receiver should allow simultaneous two way data transfer. The light sources could be omnidirectional and as the distance between the drone and the optical hot spot would be only a few metres the data rate achievable should be quite high. Possibly high enough for video as well as telemetry. Basically instead of a laser and a fibre which enables many kilometres, it would be LEDs instead of lasers and water rather than glass as the transport medium.
@@braden6973 its why I brought up keeping it connected to the drone still. Having the wireless connection still connected but able to detatch in case the line gets stuck like that again.
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.
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.
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.
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.
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.
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.
Add rocks at the front to help it sink using less power and use the propellers to control its movements. Use a latch though so it can be disposed off when not needed.
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.
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

@@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.

@@minipac2 I think putting cameras along the entire fiber line would just make more points for the line to get snagged.

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

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
Wow - I am 1000% impressed by you guys!
8:37 that controller is looking very familiar…
💀
😂😂😂😂 Well, the sub is Not Made Out of Carbon Fiber, IT should Work better 😂
😮
@@lukaskrueger3396 this is true. Oh, to be able to afford a carbon fiber sub. 😬
Awesome sub! Must be great having the knowledge and resources to build these projects. 🤘🏻
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
these kinds of vids make my brain tingle
might I suggest some sort of Carry-on handle and or wheels so it can be moved more easily?
Incredible mission, well done chaps
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 😆
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!
7:14 is that a nuke
Gratulacje i powodzenia przy kolejnym podejściu
Using furlongs for the US measurement is ultimate BM and I like it.
You really managed to capture the thrill in engineering and exploration! Gonna show that to my kids 😊
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
What a great video! I’ve subscribed so I can be highly entertained by your efforts. Cheers Mates!
Entering ecological deadzone. Are you sure whatever you’re doing is worth it?
When i heard this in subnautica i went into full panic mode lol
@@darealquest i put my thrust on 100% to get the hell away
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.
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
Fiberoptic cable is resilient as hell. As long as it isn’t cut it'll work, barely. The loss in signal strength will be awful but data can still get through.
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 !
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.
Any updates? No rush just wondering
Update: we've visited the mine for the final time, we have a result, and the video will be out this week
@@CPSdrone nice 😎stick to the plan 👽
I saw the potential problem with the cable before it happened. Good job at staying calm while untangling it. With all the protrusions and exposed props it is amazing you made it that far. I was impressed with the power of all those motors and the piloting of the drone. Great video. Subbed.
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.
Congrats for the 10M+ channel views! Keep building cool stuff.
Good job so far! Looking forward to the next video.
Great fun watching this... well done guys... I need to build one (Trimix rebreather diver)
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.
Gentelmen, that is impressive. Well done.
instant subs, this is very cool project!, hope it got a series
Great work! Amazing, really. Very inspirational. Keep it up 👏
Might be a good idea to make the drone wireless, specifically Im thinking on keeping the fiber optic cable but instead of connecting to the drone you connect it to a wireless unit that connects to another wireless unit on the drone. You could then attatch the fiber optic cable to the drone using something strong like fishing line and setup a release mechanism that lets you remove the fiber optic line from the tether and easily pull it out while still being connected to the drone.
RF does not propagate well under water. It would have very low range and would require expensive and specialized equipment.
@@braden6973 Maybe a light based solution. Using high brightness led to strobe the data. Using two different colours and a colour filter on the light receiver should allow simultaneous two way data transfer. The light sources could be omnidirectional and as the distance between the drone and the optical hot spot would be only a few metres the data rate achievable should be quite high. Possibly high enough for video as well as telemetry. Basically instead of a laser and a fibre which enables many kilometres, it would be LEDs instead of lasers and water rather than glass as the transport medium.
@@braden6973 its why I brought up keeping it connected to the drone still. Having the wireless connection still connected but able to detatch in case the line gets stuck like that again.
great job men! I think I would like o build it. One think I would suggest, use weights to go down so as not to create so much suspended debris.
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.
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.
You know this was stressful because he hit 69 meters and didn’t even pause to say “nice!”… this is truly serious business here.
This is very cool.
Good on you guys!!
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.
Great job guys! Congratulations! 🎊
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.
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.
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.
It's nice seeing fellow polish guys doing this
duuude unreal video! i enjoyed this so much! subscribed
Add rocks at the front to help it sink using less power and use the propellers to control its movements. Use a latch though so it can be disposed off when not needed.
Add some mesh to the propellers, might stop stuff from getting tangled in them
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.
Polak potrafi wszystko, bez limitu. Jeszcze znajdzie duzo miejsca zeby poleprzyc.
Pozdro!! I tak dalej.
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.
