@@qrygamer have a weight on rails that can move back and forth, connected to a sensor that can sense the angle of the submarine with another PID controller?
@@smaug131 that can work, actually. As long as u have a big-enough container and a slider that is synced with the claw. Difficult, but easy in building. U won't need a second sensor, that will start complicating things, and if you have an open area, can be easily added in.
Extremely cool. The visual clarity through the flat plexi in the front was actually astounding. This is a great proof-of-concept for a low-cost underwater remote filming rig.
It's incredible and inspiring to me that you've gone from "how fast can I make a lego wheel spin" to making things like this. Not that there's anything wrong with asking the "simple questions" but it's really a beautiful thing to get so SEE someone come up with creative solutions to make their work better. Very refreshing in our time. Love your content!
I was already impressed with the syringe being operating using a Lego motor, then the magnetic drive and everything else means this is probably the most impressive thing I've seen this year. I wonder how much it could be scaled up...
im just wondering if its possible to put like a roller in the magnet that can recess... like those tunneling drills have them.... that way it will reduce the friction even more and be more efficient while also sticking to the plexi.... even a small trenched track could be inset so only the whell/roller descends into it while the magnet rubs against the tape on glass to hold it there. That would make it even better, all while no dealing with waterproofing. But that all depends on either successfully sandwiching the magnets and roller or CNCing a brittle magnet to hold a roller, not the easiest thing in the world.
This is incredible. I'd love to see you test it's max depth. You could install some LEDs so that it the camera can still see at increased depth and tether it so that the sub can be retrieved once you lose radio control. Taking it to a lake should give you the depth and the relatively still water you need in order to test it safely
It would be great if they send a camera down, and have a remote wifi antenna that floats but with a very thin wire so it doesn't impede submarine movement.
Everything about this video was awesome from the way you designed the submarine, to the magnetic coupling. But the best part of all was the underwater view as the submarine traveled. It looked otherworldly

30 years ago I tried making a Submarine from Legobricks and Pneumatic Psarts.I tried to create an Air Bubble in a separate Chamber. It did not work that well, as connections between Bricks were not waterproof or airtight. It was a Fun Bathtub experiment. You completed it right and i can now see my Childhood Plans working as intended. Thank you so much!
True, but it also means there is functionally no chance of recovering the parts should they decide to scrap the project or if they place a piece wrong and don't notice til it's dried.
this man went from beginner to a master in lego submarine creator this is really impresive how he made it from start to a new level with different functions that he uses
Ahhh, I’m sure everyone here who’s had a Lego sub remembers at least one time they got in a tub of a water or pool with their Lego sub and pretending it dive or propel around. The memories and here we are with a creator that actually made a Lego sub, granted the Shell was not Lego due to flotation and water-proofing reasons, but I’m glad the mechanics were Lego which goes to show how brilliant the ingenuity this creator has accomplished once again for this 4.0 model. Keep up the awesome work you’ve done.
Thoroughly engrossing! This is what I needed back in 1968 or1969. I made a submarine from a Gillette Techmatic mens razor clear plastic box.I used polyester as the air source. Then I placed it in a motel swimming pool. Great fun!. Youve taken your toy to a serious level! You could sell these to pool supply businesses as an artifact recovery unit for swimmers! Great fun! Keep up the good work!
@@miladinseratlic5984 It's not the same amount of air/water, buddy. You got it all wrong. The syringe is _strictly connected_ to the water outside, and is not merely "pushing air around". It is either pushing or pulling a specific amount of *_water_* from the *_tank_* to set the *_depth_* of the submarine *_as intended_* 😒
Interesting how you went from your first videos to this. Most entertaining to me is always see passionate people in doing what they're doing best. The journey within the river is a piece of art.
This is the most amazing thing I've seen on the internet today 🤩 The Captain seems to be having the time of his life! Crusing through those waters with that music in the background almost seemed like it was hyperdrive-ing through space with starfields (the bubbles) passing by.
You make it look so easy. I bet just getting the weight of the pellets right and getting it to stay level in water was non trivial :D Such a nice job with the target depth tuning. Also getting around the drive shaft leakage problem with with magnets was super smart.
having watched the progress on your submarine projects for a while, this felt like an incredible breakthrough in capability! would love to see the addition of dive fins and rudder eventually for more highspeed maneuverability :)
Would definitely love to see the depth it could accomplish! Maybe add a bit of code, if it hasn't received any kind of input for 5 minutes, to push out the syringe. That way, if it gets too deep and loses contact with the surface, it'll bring itself back into range automatically. Maybe attach a rope to it, so if you take it out to a lake to really test its capabilities, it won't get swept away by a current.
@@Galactipod I mean you don't actually need the internals for that. Just attach a string to the camera, and fill the body with enough ballast to just sink, no need for the electronics
This is an inspiring, gorgeous project. Visually, and STEAM-wise. I especially loved the close up of the Captain! Thanks for making this awesome video.
This is exactly why it pays off to duly wait for your videos. Seemingly every time you deliver a master class in ingenuity and love for your hobby and it shows. The underwater visuals werde absolutely stunning. Thank you for using your gift to grant access to this unseen and probably easily overlooked world. Simply beatiful!! Thank you
Amazing! The view from inside the mini-submarine looks beautiful. Maybe adding a fin will help the submarine to traverse underwater better, increase stability and improve control.
I like the part where he made it a cylinder of “composite” then glued the end cap on, definitely proving that is the best design not just the cheapest and easiest to produce.
This would be a very good school project for electronic and control engineering students. Good job. You inspire people with showing many things can be built with Lego and household objects, especially for engineering students. Edit: thx for codes by the way.

You are a genius. The concept the knowledge, the skill and attention to detail. It shows a real commitment to the project. The road to this end project would have been long indeed. Well done super impressed 👏 👍.
i love how advanced those submarines have gotten over the years. hecc, I can't believe this version actually has a computer on board. (i know it's just a raspberry pi, but that's still a computer.)
I love how simple this thing is, and it really can move! It would be cool to have a tag game underwater but have a live camera feed so that you can chase other people's subs around! You might be able to make this thing even better by adding bigger batteries and more of them instead of tungsten ballast, more power with the same weight!
Something I would absolutely love to see with this would be features for longer-range missions. Equipping it with an FPV system and long-range controls would be really fun to see!
My thoughts as well. So many small-form-factor LRS control setups available these days… coupled with HD FPV (they’ve done amazing things with reducing latency, and with a sub it wouldn’t be a huge deal anyway). I was thinking waypoint pathing, or LRS. This is so cool.
That's very cool! For the next iteration, consider adding heading control using a gyroscope and magnetometer. I added it to my combat robot and it really helps to keep things moving in the correct direction. You should be able to get all the sensors you need on a single board that can plug right into the Raspberry Pi and communicate over serial or I2C. They are often referred to as a 9DOF IMU.
I would be interested seeing this float around a large lake or the ocean with you following along in a boat. I don't know how much your budget is for this channel, but that sounds like a very fun idea. Great work on this, your iterative designs have been very cool to see.
I think Hull Volume would be a good addition to the spec list in the description, in order to compare with the displacement. It's 2.376 litres by my calculation!
These videos make me wish Lego was pushed more as a edutainment because these videos are so cool and I feel like this kinda stuff can help get kids into engineering
I get what your saying but making a submarine capable of reaching the insane depth of the titanic with people aboard is a lot more complicated than this. This ROV would implode before it even got half the depth.
@@ADRIAN-zh4ti For a fun comparison, 2000M depth is approximately 190 atmospheres or roughly 3000 pounds of pressure per square inch. That would be the equivalent of balancing a Toyota corolla on a one inch wide section of the glass.
@@wyatt-mv6pd the problem was that these dudes were billionaires and they were told beforehand that the submarine wouldnt be safe for going down that far, and the guy that warned them about that got fired for it
This is just the kind of toy I would have loved as a kid, exploring the rills and swamps near my family's home. Of course, certain tech advances hadn't been made yet, like phones were still attach to the walls and color TV was a new thing. 😁 All the same, 584 lines of code to run that thing? That takes it out of the realm of toy, doesn't it? You have my respect.🤩
Ideas: 1. Make submarine bigger, more powerful, and more durable. Use it to explore big lakes, rivers, public pools, whatever: - more Lego motors for faster speed and carrying more mass, or motor bought on Amazon and connected to Legos (nobody will blame you) - bigger container to fit everything 2. That's another very very ambitious idea: antenna relays. This will probably help make your submarine truly long distance. Simplest way is to just take two different antennas, and make one relay signal of previous one. And have the sub accept signal of all of them, OR-ing it (if at least one antenna connects, it will work). Might seem like not an elegant solution, but I think it requires the least programming. You can place the relays along the river by hand, and it will greatly extend your range of control. The more ambitious idea is to make the relays placeable by submarine. Make few mini modules connected to the sub externally. It should have a way to connect and disconnect them. Need to find simple way like magnets or whatever. Modules need to be neutral buoyancy, and contain relay antennas and other stuff to relay the signal. Maybe ways to attach to the environment are needed, like anchors. Maybe it's unrealistic to expect this, but it would be cool. 3. Create Lego gripper. Simplest way is to create "jaws" in front of the submarine, opened and closed by engines with gear ratio exchanging speed for power. Maybe try catching fish with this?
The underwater footage with the sounds of the sub was out of this world! Such amazing view. To think it was just ordinary shallow stream or pond maybe.
What a technical achievement for version 4.0! Legos do have their limits, but I love this mix of skills. All that's missing is the real shape of the submarine! Well done!
YES! THE RETURN OF THE CAPTAIN!. I've been waiting for this series for so long since the 3.0 release 10 months ago. Thanks, the child in me really thankful for the joys. I mean not literally there's a child in me.

@@ADRIAN-zh4ti For a fun comparison, 2000M depth is approximately 190 atmospheres or roughly 3000 pounds of pressure per square inch. That would be the equivalent of balancing a Toyota corolla on a one inch wide section of the glass.
@@wyatt-mv6pd the problem was that these dudes were billionaires and they were told beforehand that the submarine wouldnt be safe for going down that far, and the guy that warned them about that got fired for it
That lake tho
The balance of super simplicity and technical complexity of this sub its outstanding.
I swear it's only a matter of time before you build the first fully functional Iron Man suit out of plastic bricks

One of the best lego Projects I have see. So far. Great engineering.
This is just the kind of toy I would have loved as a kid, exploring the rills and swamps near my family's home. Of course, certain tech advances hadn't been made yet, like phones were still attach to the walls and color TV was a new thing. 😁 All the same, 584 lines of code to run that thing? That takes it out of the realm of toy, doesn't it? You have my respect.🤩
i wouldve guessed half that many lines wouldve been needed
going through the stream was beautiful! these submarines are getting so impressive
This turned out much better than expected, nice work
Your magnetic water tight coupler is genius! Very interesting video!
I've followed this since version 1, Tupperware to a custom acrylic shell. Direct drive to magnet drive. Great job with the sub.
Прекрасный проект! Идея с магнитной передачей просто порвала мой мозг, это никаких тебе сальников и вечных течей...
Также крутая идея с шприцем.
Ideas:
1. Make submarine bigger, more powerful, and more durable. Use it to explore big lakes, rivers, public pools, whatever:
- more Lego motors for faster speed and carrying more mass, or motor bought on Amazon and connected to Legos (nobody will blame you)
- bigger container to fit everything
2. That's another very very ambitious idea: antenna relays. This will probably help make your submarine truly long distance.
Simplest way is to just take two different antennas, and make one relay signal of previous one. And have the sub accept signal of all of them, OR-ing it (if at least one antenna connects, it will work). Might seem like not an elegant solution, but I think it requires the least programming.
You can place the relays along the river by hand, and it will greatly extend your range of control.
The more ambitious idea is to make the relays placeable by submarine.
Make few mini modules connected to the sub externally. It should have a way to connect and disconnect them. Need to find simple way like magnets or whatever. Modules need to be neutral buoyancy, and contain relay antennas and other stuff to relay the signal. Maybe ways to attach to the environment are needed, like anchors.
Maybe it's unrealistic to expect this, but it would be cool.
3. Create Lego gripper. Simplest way is to create "jaws" in front of the submarine, opened and closed by engines with gear ratio exchanging speed for power. Maybe try catching fish with this?
I'm declaring this the coolest thing I've seen today and it's only 7:53 EST
I still remember the pitcher submarine. The lego mariner have come so far. Nice video as always and looking forward for new projects or concepts.
This is by far the best sub-marine video I have seen on youtube. Exceptional work 👍🏻
Dude you should try it in the ocean🌊🌊🌊🌊
We need more of this 🤣 just go to random lakes/rivers, I could watch you exploring underwater for hours
I totally aggree, more videos of underwater with that music
Это просто офигенно!!!
Съемки просто шикарные!!!
This channel is the DEFINITION of worth the wait
Your video made my day a little better.
That is truly amazing, would love to see a larger version to go much deeper ❤️
This is soooo cool, love the depth sensor connected to the syringe
Suddenly was reminded of this amazing vid
Just the sounds from the sub working bring the Spiderman: Into the Spideyverse soundtrack into mind.
What a great project.
This is incredibly cool! I loved seeing the controller do its thing to maintain depth. Great work!
The underwater footage with the sounds of the sub was out of this world! Such amazing view. To think it was just ordinary shallow stream or pond maybe.
Watching the underwater footage made me want to be a fish, ngl.
This is an amazing creation, well done! Brilliant idea using the magnets and smooth tape to drive the propellers on the outside.
What a technical achievement for version 4.0!
Legos do have their limits, but I love this mix of skills.
All that's missing is the real shape of the submarine!
Well done!
It's like you could build a nuclear robot completely out of Legos. Most impressive 👏
It's amazing how compact and functional it is. Much better than the previous one.
YES! THE RETURN OF THE CAPTAIN!. I've been waiting for this series for so long since the 3.0 release 10 months ago. Thanks, the child in me really thankful for the joys. I mean not literally there's a child in me.
