for RC underwater stuff i think having a rescue line on it at all times seems like a good idea.
just a rope and a yoga ball with a handel for bouncy but you need a kayak to go get it
Great idea you can get floating rope for throw lines that would work great from the floating part to shore. Then it won't tangle the rover
Maybe the float could have a winch on it as well as its own motor
@@listaro4128 Maybe some way to inflate a balloon to get it to float to the surface?
@@Oldsmobile69 CO2 canister and a balloon, yes indeed.
its a shame this is a limited project, I'd have liked to see this project develop a lot more, It's an awesome concept.
🎉😂
same but i don't blame him
This was a great project! I have two suggestions.
1. Use a compass to get an idea of the direction you are pointing.
2. Strap a "safety balloon" with a co2 cartridge to it and inflate the balloon if you get stuck. If you do it right, it will stay upright and lift the top of the tracks above the water so that you can use the tracks to "paddle" back to shore.
I was thinking about a winch on the barge, but a co² safety balloon sounds a lot more fun
@@phirenz I guess that could work too. But he would have to add propulsion to the barge or inflate his kayak to retrieve it.
Was going to comment exactly that! Nice work Mr G
@@platima Thank you sir
Would a compass work okay under water? Also surrounded by those two motors? I thought he should use a gyrometer or something to keep an idea of orientation but it would eventually build up some error.
I really want to try this with one of those spider robots underwater
FPV crab???
@@rctestflight yes sir
@@ruska9773spider crab 👍
I'm still waiting on the crab drone video!
i think part of the issues have to do with inherent features of the lake bottom - as a low-energy environment with almost no current, the sediment will consist almost entirely of silt, clay, and fine-grained biologically-generated material. this has the effect of: 1. making it harder to drive as you'll tend to stir it up and sink in, and 2. meaning that any sediment stirred up will take a long time to settle out, so driving will inevitably make it very cloudy.
btw that smell of lake sediment is often due to methane bacteria :)
While I agree, notice the lack of actual imprints from the tracks? Those tracks help spread the weight out enough to minimize that. I think this is a good starting point for submariner rovers.
I used to go kayaking in the local canal with the Scouts and you could prod the mud with your paddle and a load of foul-smelling bubbles would come out.
Maybe a screw tank would be better in this environment, because it never has to double back on itself like tracks or wheels do. All sides of the screw will give forward thrust. Screws will even give you thrust without touching the bottom.
@@TheAnoniemo brilliant. The sides would have to be counter rotating, I assume...
@@mike_oe Yes
Also you can have a bobber on a shorter tether as deapth gage, so it gets pulled under before the main tether, then you know when to turn back
if you look closely he did that after the first test
It would be cool to attach a water sensor to the float to send back a telemetry signal if it gets pulled underneath
@ no that's different, that's a bit of foam to add buoyancy to the tether so it doesn't drag in shallow water
Hey Daniel ! For the video signals you definitly should use coaxial cables. It will have a "shield" functionality and will prevent the video from being jammed by the other signals such as power or ESCs. As it's low speed signal you don't care about impedance and can use both 50 or 75ohm cable. There are some really thin ones available. All you have to do is solder the signal on the inner line and GND on the shield on both sides (rover and barge). Hope it helps !
Yes using a coaxial cable is the proper thing here, but as far as I am aware the signal from the FPV camera is composite video. Composite video was designed for use with standard FM/Broadcast TV coax which is 75 ohm. It's possible it will work fine on 50 ohm, but it's supposed to be 75 ohm. 75 ohm also happens to be the most available and in some cases cheaper than 50 ohm. My recommendation for him would be RG-59, for the 40 foot tether, the video signal and cable structure should be plenty strong. Like you said, make sure you ground the outer shield. Particularly at the camera and transmitter, not just any power ground as ground current could actually cause a similar interference problem.
Also secondarily, run the video signal as a parallel tether, not shared with the power cables (That's what's causing the interference, not the 5V PWM signal, the battery power creating a magnetic field.)
Also...batteries in the robot itself will minimize or eliminate most of the weight of the tether, while also acting as weight to keep the robot at the bottom, and will allow you to use a smaller BEC circuit to power the surface equipment, and keep the surface float smaller.
There's some stuff regarding UUVs that is significantly different from normal RC stuff, because of tether lengths. You'll have a LOT of power loss over the length of the tether. Ideally, you want to use the minimum number of wires in the tether possible. For that, I recommend just the camera+ground, and 4-wire serial connecting two controller boards (One translating the receiver's 2-3 channels to serial, the other translating back to PWM) with a power booster every 50 feet along the tether. Batteries CAN be submerged if they're in waterproof boxes. I use Otterboxes, which can double as tether floats, and run my ROVs down on 200' tethers made of Ethernet cable.
If you need to waterproof, there is a product made by Lawson called LPA III. It's basically lanolin and parafin wax in a acetone solvent. When you spray it on electrical boards it waterproofs them. I've tested this for underwater operation. It's better than potting because it allows for heat dissipation and can be removed with a solvent safe for electrical boards. You could seal 3d prints with it as well.
This is INSANE, daniel! Wish you and your community here a merry XMAS! 🎄🎄🎄🎄🎄
I love you pcb!
no way, he is called Daniel too?😯that's why he is so amazing
So what does pcb stand for?
@@unitedunitedunited_ Printed Circuit Boards
the video is before 2 hours
This is a great concept ! Once again your crazy contraption is amazing ! My suggestion for “version two” would be to have a larger surface barge and a small additional spring loaded cable with an electric winch to lift the underwater rover in case it gets stuck or fouled in the weeds.
I agree with you,plus it'll be nice if he added propullsion motors motor like a sub one or two just in case he got stuck underwater i think that would be a great help.
Give the barge propulsion too - it could go out and drop the cat into the right place, and bring it home
I am not an engineer, but i think, that he should cover the upper side of belts.
@@petainfinusvaverka4686 water would still get in but then it could more efficiently generate thrust against the way you are going. Now im curious. If anybody has an answer please let me know.
The raft should have enough buoyancy to lift the rover with a winch for either a cable or directly to the communication wire. Maybe a couple of motors to raft with propellers attached to retrieve. Though this would be somewhat over engineered.
This is one of the most interesting projects I’ve seen recently, I’d never heard of those methods of waterproofing electronics before and I think underwater RC is just such an interesting concept! This makes me wonder how to build an underwater rock crawler and do some submerged off roading…
It's super easy, I do it...frequently...
I'm known as a submarine driver among the crawling groups I'm in, because it's not unusual for me to drive my crawlers in 2-3 feet of water. I use waterproof potted air receivers with the peripheral antenna mounted on a long-snorkel (sitting 18" from the ground) so the most it gets is 18" under, which is right about where the Spektrum DSMX frequency starts to fail. I've gotten as much as 22" of water between the antenna and the radio and been in control, but it's spotty at that depth)
Honestly I am never tired of watching your snowcats especially with some beautiful scenery in the background.
absolutely LOVE underwater stuff! would love to see more things like underwater crawlers and ROV's!
As far as day to day environments go there really isn't a more destructive one then the marine one. its ability to silently destroy has to be admired in the endless ways it attacks systems haha.
Keep up the work man, you make me wish I never stopped building and experimenting with theses things.
What a way to show how versatile your platform is! Also wanted to say that i'm completely in love with this seabed crawler idea and very impressed with your quick adaptations to make this thing not instantly die underwater. I would greatly enjoy followups for this branch of the project.
❤
You are a crazy nerd! That is a genuine compliment by the way. It’s people like you who make the world go round and then explain how you do it to the rest of us. So cool in such a nerdy-geeky way. Thank you
Should have paddels that fold in one direction on the tracks :)
Awesome build!
think about it once again
@harrie205 a pin to to raise them on the front wheel and an elastic string to fold them down on the top side, should work fine?
would make reversing and skid-steer less possible
Awesome prototype! It would be really neat if the barge was RC as well, with a winch that could raise and lower the rover to help recover it or place it in specific areas
That idea is actually poggers but would require a pretty large and stable barge or much smaller rover
you should definitely explore this concept more! it looks really cool driving underwater!
I love the concept... the view driving across the bottom while exploring is for some reason more satisfying than the view from a submersible. I'm a scuba diver but the idea of "4 wheeling" on the bottom of a lake or sea, just seems cool. Well done
Imagine driving a full sized vehicle down there instead of a full sized submarine
The way the sand goes over the treads is insane looking!
Sweet! Now make your barge RC with enough power to tow the tank and even winch it up off the bottom!
Such a great video! It’s fast paced enough so I don’t need to skip ahead. Very well put together. All this information is great
Submarines are cool and the FiFish looks pretty neat, but the idea of an aquatic crawler is so much more interesting to me - it's almost like driving on the moon. It might also be cool to tow some kind of camera-torpedo behind one of your boats, with a lil mechanism to reel it in as needed. Great stuff as always!
0:43 So it's just you sir! Any video that you made was excellent and catch the attention easily. I bet that even a video about that RC in the snow would make any person like.
Have a great day, don't overwork yourself, sir!
I like magnetic couplings for this application. You know what would be cool? A set of tracks that was directly linked to an interior drive band via magnets.
For a first prototype,this is an outstanding success! Underwatering is hard. 🎉
Dan you are absolutely incredible! Your ideas and your creativity is out of this world! Love the channel! Happy Holidays!
I love this channel so much, it deserves to be bigger
You should totally do a screw tracks! They would work so much better than treads! This project is so cool and I would love to see it continue!
Absolutely awesome as always. I've always wanted to diy my own ROV. You should look into removing the mounted ballast weight, and look into making some sort of emergency cutaway balast. If you get stuck, or too deep you could flick a switch and float to the top, leaving the balast as a reasonable sacrifice. The hard part is making it water tight... If you use steel plates for your weight, you could use magnets mounted to actuators of some sort to engage/release. Then you can use a magnet on a rope and the blow up kayak to recover your weights. Just an idea for if you ever revisit this.
Tremendous work guys, hats off to you! Huge value in the work you are doing, I bet it would have cost BAE big dollars to get this far. Talk about "agile engineering" - I think there's a lot the "big boys" could learn from your approach to getting things done. Keep on!
Better than oceangate
See you in hell
Whaaaayyyyyy!!!!!
Nice, dude! I think the aquacat v2 might want additional weight for traction or alternatively a propeller to make little hops over obstacles.
You just build whatever you think of without even thinking if its possible. incredible
This awesome, I love this underwater exploration. Couldn't help but think you need something bigger. Best to you and happy holidays!
Jesus
Ive been watching you for ages now but holy shit, this is it Daniel. This is what we want to see. Do more of this underwater stuffy
In the future for small amounts of moisture, you can buy silica gel cat litter for extremely cheap compared to the packets made for drying.
Drop a few granules inside the “dry zone” and you’ll be good. I keep 3D filament in a big Tupperware tub with the silica litter sprinkled on the bottom because I live in FL and it’s swampy as hell, but the filament stays crazy dry! The stuff works incredibly well for how much you use. Literally a few granules would keep a housing like your camera dry.
It’s useful stuff, you can use it for a ton of things you probably wouldn’t think about until you have it.
Ok.....I gotta make one now. I love the floating barge idea. That honestly is the best part.
Id love to see this project revisited and improved upon. I love the idea!
I found the bit about using mineral oil to flood the electronics pretty interesting. For the tank, i wonder if it would be feasible to turn it into a submarine hybrid which would allow it to get out of trick situations, by filling tanks with air and becoming buoyant.
VERY cool concept, been a dream of mine to build/own something like this since I was a child, so cool! Maybe a longer tether and a boyant safety string attached to the barge/boat for emergency recovery as an upgrade? Would love to see more and deeper exploration!
Oh, this is so cool! You could add a motorized reel and make the barge basically an R/C boat. That would allow you to go deeper and hoist back up in deep water for the hills. Awesome job!
this has been my favorite build so far, i hope you keep developing it.
I can't wait for more versions of this! Super interesting
This seems like a very nice platform to have underwater manipulation arms since it would be super stable!
You should totally patent this, great Idea.
Please do more underwater projects 🙏🏻 it's so facinating to see things explore the depths. There's so many things you can have fun with doing around the area that you are. You never know what you're going to find. A insta360 camera could create a really cool perspective as well.
part 2 please, this project is super cool
Fpv camera condensation... I've had the same thing flying fpv in the winter, and I'm pretty sure the heat the fpv camera pcb gives off is what disperses the condensation. Thanks for all the videos, love the content.
Thank you for pronouncing silicone correctly, I had never thought it might be corrosive. Very impressive re-spin of the snowcat.
YES! that thing is cool as heck!! do a longer tether for sure!!
What a great project - a huge learning curve 🙂
I used to work on Submersable ROVs - Have you considered using a perspex (or similar) dome to house your electronics, camera and lights in? Also how about a couple of thrusters to help you out when you get stuck.
Well done on what you achieved - you do some amazing projects 🙂
The mineral oil being non conductive is really cool to know! If I remember correctly from my hvac classes you REALLY can’t use that stuff cause it eats away at the metal or something.... or mineral oil was good and the other option were terrible... I’m pretty sure it was the first though cause I can’t shake the feeling that mineral oil is awful because of some esoteric reason I can’t remember.... they threw ALOT at us each week in those classes.
Can't wait for part 2 this is the best so far
Hello rctestflight, love the video. For fixing your interference issues, I recommend using a wire with screened twisted pairs, then be sure to ground the screens. I work in the sensor industry, and we use these in all sorts of high interference environments, and they always work.
So much better than my tethered submarine 🤣
More underwater content please :)
Awesome yet again, I NEED one for the water tank inspection.
Improbable explorations! This is the lunar edge of mobile experiment.
Only you could grapple this this back home.
Gotta use this to find the titanic sub
why did you go through all the trouble to seal the motors? aren't brushless motors sumergable? was it to keep the bearings fresh?
Brushless DC motors can be used subsea no problem at all but requires regular flushing with fresh water after each dive.
It's a cool RC that I didn't even think of. It's just plain looking, but it works great.👍👍👍
I've been wanting to do a (non-rover) sub + boat combo for ages and wasn't sure it would work. This video is inspiring, thanks.
maybe include an emergency ascend mechanism and include motors in the surface craft.
for the emergency ascend you propably just need a few balloons and a co2 capsule and something to connect these two
...or a way to drop ballast.
What if you added a solar panel on the raft so that the battery drains slower, Wouldn't need to worry about cooling since your surrounded by water.
Favorite project so far!!
ALWAYS with the cool and interesting RC projects, congrats on another great video. All I ask is that you just keep being YOU, since being you results in a lot of cool shit happening.
A fan from Iraq🤘🏻🇮🇶😎
Favourite printer? Worst print quality ive seen😂
Thats freaking awesome Daniel! I love your one-off builds. Merry Xmass and Happy New Year!
This has got to be one of your best projects ever!
Really liked this one can't wait to see where it goes!
You do great work. Merry Christmas 🎄
Footage of it driving was better than the POV. Cool project over all.
thankyou for this , great project and great lessons for every DIYer.
I just want you to know that when I saw you had uploaded I literally said “Oh hell yea!” Out loud.
Love the content man
Awesome stuff you’ve done here. As for using 3D printing for low-pressure watertight enclosures I’ve personally had success using extremely fine layer heights with vapor smoothing. (I use ABS with acetone, but you need a pretty big skirt so it doesn’t warp). I make the walls a little thicker, but you don’t need 100% infill. Where you’d like to screw in flat surfaces like that plexiglass you have to sand the plastic as flat as you can get it (which it looks like you’ve done here). Barrel sanding techniques work quite well. In order to make that process easier though I’d reccomend using some automotive water pump gasket material with a set of cheap gasket punches for the screw holes. Works wonders. Made everything from submersible enclosures to PC water blocks with this method.
Best of luck!
Great project! Would love to see this taken further.
We need more versions of this! its so cool!
Not even joking, this is the type of stuff I wish Mark Rober would do too. You are absolutely killing it my man, headed to watch your newest videos next
Super fun to watch, thanks for sharing.
Great chunky designs Daniel. May the stream be with you❤
This was actually a great idea, taking it into the waters. It's really cool and interesting at the same time. Good job! Oh, and Happy Christmas
You are soo lucky with animals wanting to be your friend and you just break their trust! Madge You are a meanie! - Love your vids, as always :)
This is the coolest thing you've done.
It's interesting in the water.
The images are also beautiful.
Incredible. Seems like it'd be perfect for inspectors.
bro this is awesome... I'm in rc for a long time but you had so many good ideas here, respect!
I took my rc boat to the beach.. most fun ive ever had with it jumping wakes and doing turn arounds on wakes!
Awesome! Very entertaining project - love it! ♥
This highlights how impressive the successes of all the Mars rovers are.
Yesssss! bring the tank kit back!
Man you’re the coolest dude I’ve seen today!!!! I subscribe !!!!!
Ingenious! Very cool video
This was the coolest rc yet
This is a project that needs a revisit. How deep could you get the tank to work? A lot of this doesn't actually need to be water proof? Just keeping the sand out? Would a big floating barge with a solar panel be able to supply power for unlimited tank range? Also a nice long range antenna? Then take it to the beach and drive out through the surf to 30ft depth? Maybe large diameter wheels instead of tracks to keep it away from the sediment?
Dude your videos are such good ideas and really entertaining!
Amazing video and each voice of your hardwork I salute broo🙏
That is so cool. Please make a non-RC-version that tethers to your boat so you can explore deep lake beds!
