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!
Dobrze widzieć kreatywnego Polskiego youtubera z takimi wyświetleniami i fajnymi pomysłami🙂
Polska gurom
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
@@CPSdronefill the electronics housing with mineral oil so it can't be crushed by the water
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
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.
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.
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.
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!
You missed the opportunity to use a logitec controller
For the memes!
lol
He still used a ps4 controller
Hilarious
One of the videos they showed did 08:37
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
A buoy with some anchors and a pully.
"it swims violently" killed me
this is the first sponsor i can actually use.
i am very happi :)
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
Panowie wielki ,wielki szacun.Emocje niesamowite tak jak praca włożona w ten projekt.
Pozdrawiam serdecznie i oczywiście czekamy na część drugą 👍
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.
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 !
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.
Thanks for showing off my CPS5 Drone in the last Video.
Keep it going and to anyone else, you'll need to enter the Course because it's totally worth it.👍
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
The fact the drone worked at all, with that much tangling, is amazing
Might need a distance based tensioner?
The industrial design in this is phenomenal.
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.
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
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.
you should add a sort of mesh tube around the fibre, to prevent it from being worn against obstacles
😮
So glad you got the drone back. Fingers crossed for the next go!
ah yes the thing covered in uranium particles
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.
gotta love the resiliency of fiber optic. this was a very exciting video
Can you build a under water drone that mines the uranium? Please ☢️
thats like super illegal i think
@@FyreflyeVR Yeah, but woud be funny☢️🧪
@@3AM_Ideas it would be profitable and non illegal actually
nice try Iran
@@edheadgaming8411 hold my beer
Good job! Your close to getting to the lost river! 👻
subnautica reference?
@@KarlDRG yeh
Was searching for someone from Subnautica in comments lol
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.
Adding a very thin mesh around the propellers may avoid anything from entering them, but still allow water flow out.
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.
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
i love how he sits there in front of the screen looking like a kid going try hard in call of duty
Adding a 360° camera... will solve the problemS !! Good job guys !! You will be surely on this business in the next years !!
When you'll need an International salesman or representatives 😀, I'm here !!!
Zajebista robota, Panowie! It is pleasure to watch fellow polish engineers, yet still I am really suprised you are so persistent on idea of that drone being used in that scenario. That drone may be strong and universal, but while being focused on crating a drone that could reach the bottom of the mine shaft I'd rather build something bell-shape-based. Still, on open water that thing must be a beast and I am really in awe that the fiber cable was still working after being mauled like that. Keep on keepin' on!
That was some good piloting and decision-making right 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
if you make the electronics capsule a proper airtight pressure vessel(doesn't explode with internal pressure) you should be able to pressurize the capsule to 90-150 psi with air while on the surface. This would buffer the capsule and reduce the maximum pressure delta the capsule sees. The more pressure you can get at surface level the deeper you can go before the stress switches to compression.
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
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
I like how they went though all the trouble of designing and ordering custom parts, but leave but fiber optic extra super duper vital lifeline cable raw and exposed.
You might consider having a mesh go over the ports where the motors are to help keep them clear of debris, but nothing too small of a mesh or it will easily get clogged by smaller pieces of debris
I appreciate the translations into American units besides the metric ones. Great video and awesome project!
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 😆
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.
Well done lads good work, exciting to follow along with you both. Result you got The unit back
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
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.
I think "swims violently" is now among my favorite phrases
Super dron i fajny film. Takiego polskiego youtube’a to można ciągle oglądać. Powodzenia z projektami.
might I suggest some sort of Carry-on handle and or wheels so it can be moved more easily?
you deserve a million subscribers keep going!!
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.
The funny thing is that you can actually bend a fiberoptic cable and loose the signal, then bend it back and get the signal back!
We actually had this problem with our internet connection, as the cable was bent on a sharp point. Bending it back fixed it again!
7:14 is that a nuke
Ngl- I feel like the best upgrade to this design to prevent what you showed happened at the end to it with the cables and that random line from the mineshaft- is to put mesh guards around either side of each of the propellers to protect them from that kind of thing happening again.
Other than that- this design my actually be suitable for doing what you ultimately want to do- and might be able to reach the bottom.
Man, I'm currently studying for an engineering degree and it's videos like this that make me remember why I entered the career in the first place
idk why i find it interesting that they go back to speaking their language and you just KNOW their in hyper focus mode. its cool.
Now this video is the reason why we love our engineering nerds, this is an awesome project. Hyped for the next adventure.
Consider building a propellerless drive. Not nearly the power but nothing to tangle into. You could also add a mesh over the propellers, impedes the force as well but lowers the risk of tangling, it's easier than building a propellerless drive. Add a sonar communication channel to it, so in case of cable breakage,you could at least slowly command it to do stuff via sonar.
Very nice graphics/animation to explain the tangle. Nice sub too.
Using high performance car parts can also help form good seals like turbo gaskets and spacers. They are not “that” expensive but are designed to support very high air pressures and compression.
3:00 one inch away from loosing a finger, pure engineer power
idea. use a rope and a weight guided by 4 motors to go down faster but still able to go around obstacles, use the rope for depth controll
I think it might be a good idea to add a floating tube every 1ft or 3ft such that it kind of balance out the gravitational force of the cable such that it will stay in the center of the vertical and horizontal shaft.
You guys are insane, thank you so much for the awesome video AND the free training course! I am super excited about this
Add a screen over the propeller "tubes" so nothing can get cought in them but can still push water through for motion
I would suggest adding an Insta 360 camera or something of those sorts to look around better. While yes you might just need a rear camera, having the abilty to look around the submarine in any direction would be much better.
I don't think most people know what a furlong is here in the US. It's a very obscure unit of measure these days. We just use miles now. Awesome video!
Suggested upgrades for next mission:
- protective mesh on all propellers
- back camera
Can’t wait for the third try!
For the tangling, how about adding a mesh both side of propellers (no screwing it, maybe stick)
Would be really cool if you could attach LiDARs to map out in a 3d model :) Would be SUPER handy if you would be going cave exploring with this thing
I was ready for some Subnautica content. But this is much better.
You should've put the cables cables into some protection layer, and made them thicker and stiffer so they wouldn't tangle or get stuck so easily.
It's nice seeing fellow polish guys doing this
Relying solely on a single fibre optic cable tether is risky. Reenforce the optic line by wrapping a backup line to it. But mount the backup in a way to leaving some slack in the fibre optic cable near the sub only.
See the rope techs at 5:36 was pretty cool, I happen to be a rope tech myself.
Rim driven thrusters would've saved you from the issue regarding random lines floating around, in the tunnel, since it would push the line through, without tangling around the thrusters. It won't, however, save you from the issue with sucking in your own tether cable. I've experienced similar issues several times on another drone. Guard shields is one way to do it, though you will lose a bit of thrust doing it...
You guys should set up a pre-assembled umbilical cord for your optic line and a retrieval line!
One idea would be to add spool of cable on the back of the drone that can spool out. It could also be of smaller diameter not meant to reclaim but In the event of an emergency to recover the drone then be cut.
Using furlongs for the US measurement is ultimate BM and I like it.
you need to add a 360 camera so you can get a 3rd person view of the submarine. kind of like how some porches particularly my cayennes proximity sensor works. it shows a 3rd person birds eye view of my car on the screen. then you can avoid all obstacles, you should also consider adding thin fine steel mesh in front of the propellers to prevent nylon fishing lines or other small debris from getting tangled. good luck
You should integrate a way to hold backpack straps in the design so the sub can be easily carried on your back.
You should probably use a separate steel cable as a tether and put a strain relief on the fiber optic cable.
When you add a mesh, you can also add a cutting knife that will get rid of fishing lines just like modern boat propellers. A fishing line is very small and can always reach the propellers, but you don't want to cut the fiber cable when it gets tangled because it has no mesh.
That recovery effort was more exciting than a lot of movies 😂
you should put a mesh of some type over all the water intake and outlets i think that would solve your cable tangling issue
For your next design, design a craft that uses a single oscillating propeller in the center. That will be interesting.
Perhaps putting some sort of Mesh or grill over the Rotor assemblies could help prevent any unwanted debris from entering/coiling up in and around therefore preventing any steering problems.
You should add a camera on the back of the submarine. Next one should have some tools like scissors/claw to move and cut things 😃
I know you would loose some thrust but perhaps a mesh cover for the propellers would stop most tangles
The best sub drone build by polish students.. Zajebisty.. !! Greeting from a turk ..from germany. 'Pozdro !
Just an idea, install a cable cutter and make a sonar unit that maintains the drone in the centre of the shaft, base it on a flight controller maybe?
You really managed to capture the thrill in engineering and exploration! Gonna show that to my kids 😊
these kinds of vids make my brain tingle
