I really like that you can see the balloon expand as it ascends--it really illustrated the instability of this depth control system, which scuba divers would likely be familiar with!
Yup. As you rise, pressure drops so you need to reduce the air volume in your buoyancy device (baloon in this case) to maintain neutral buoyancy. If you don't, your rise will accelerate as your positive bouyancy increases at an increasing speed and your sub shoots upwards (and could get the bends :-))
The level of confidence to put it in an actual river is staggering. Also, if this guy builds a Lego rocket and lands it on the moon or a sentient Lego robot I will not bat an eye

The thing is, submarines don't only use ballast tanks to control their submersions. They also have side fins for fine tuning. Also without automatic pressure controller it will be extremely difficult to keep steady depth. I still would give 10/10 for really cool project.
Side fins only work in motion. But the real difference is the displacement of the vessels. The margin of error is 1000000 times bigger (or around that ball park) on an actual sub so tiny changes have less effect.
Also this buoyancy system has the problem that its equilibrium is unstable: if it surfaces a little the water pressure lowers, the balloon expands and the submarine has more buoyancy, surfacing more. Opposite if it goes a little deeper, it wasn't to go even more deeper.
@@rayyaninspookymonth1630 even though I'm high functioning psychopath I have adhd thus my impulse control is low. Because of that I don't really trust my self
this has gone from "cool proof of concept" to a serious project iam following with passion... and you totally had me with the small magnets... its a really creative solution
The brave, fearless captain, knowing how the vessel is only a prototype. Gladly sails the underwater abyss. While screaming internally that he's about to die any second.
You can add a ballast tank inside the submarine by replacing the balloon that pumps air in and out of the hull with a balloon inside the submarine that pumps water in and out of the balloon that's inside the submarine. This will allow you to; go deeper, be able to keep a stable depth, and not have to worry about the water pressure. (You may have to take out some lead pellets for more room) You could also put the go-pro (or some other camera) on the front of the submarine so that you can see where your going and explore the bottom. And if you're realy ambitious, you could add lego arms to allow you to grab items on the bottom. This submarine is very impressive and can be used to find things like; good fishing spots and valuable items on the bottom.
The first thing I'd add would be an emergency surfacing system: A piece of (scrap) metal on the outside of the submarine bottom, held in place by a magnet or few inside the sub. There would be a motor (or better yet, a spring with a trigger) to retract the magnet from the proximity of the bottom to further inside, so that the piece of metal would drop off and the rest of the vehicle would surface even without the balloon. This mechanism would be triggered automatically after a certain time of no radio input (indicating lost connection) or if the outside pressure goes too high (indicating inability to surface by normal means i.e. the balloon).
8:45 Yes, this is something divers have to learn about. There’s positive feedback in buoyancy because as you go deeper the same amount of air will displace less water and vice versa, so you need to actively adjust your buoyancy compensator
@@MadofaA considering both your exposure protection and your lungs impact your buoyancy, that's not possible without an actual pressure suit... something unavailable outside military or deep commercial diving operations. Thus your point is moot.
@@elucid07 Yeah, of course youk’re right, but I was more refering to the submarine in the video. The reason he can’t control depth and get it to “hover” mid-water is the use of a compressible buoyancy tank (balloon).

It is so good to see engineering like this put together step by step. It all looks so complicated but, when building, it is just a load of simple parts. It takes a special brain to know how to put them together in the right way though. Love your videos. Thank you.
I'll bet all the old tech and mech engineers watching this are saying: Well in my day you had to engineer all the parts yourself, these lads today have it so much easier.
@@2teethPogZa - if the balloon pops the sub will fill with water (eventually), and most likely destroy the electric components inside. So a little to worry about, also the safety line is thin, and will most likely snap if he is trying to pull in the large metal item it was caught on/in :ø)
You need some compressed air in a seperate tank inside the sub. And another one. That one is filled with water at the Start. If you pump the water outsides, you can control the depth. And dont forget: your sub seems to be heavier, when it is slowly. So it will sink :)
Unless the sub checks for radio contact at regular intervals. If it lose the signal, it can automatically start surfacing. And with that, the need for backup systems shows up. So an internal tank for water, that is blow over board with an internal tanks pressurized gas, and thus even with ballast, the sub should be positively boyant to begin with.
@@Thomas_Bergel The concern with a safety line, as we saw in the video, as that since you can only pull on it in a single direction, it's very easy for it to get caught on debris. I'm definitely in agreement with starting with a slightly positive buoyancy in order to prevent accidents.
Super cool! Maybe you could try adding rotateable "wings" that generate lift? That way you could match the water density as closely as possible, or be slightly more dense, and go up by increasing speed/angle of the wings
Brave to use an unprotected latex balloon right next to a propeller and go diving in a natural body of water full of rocks and sticks. If that balloon popped you'd never be able to surface. Looking forward to seeing what you come up with for the next Lego submarine.
I don't think there's nearly enough pressure in the balloon to make it easy to pop. Wall thickness is determined by how stretched out the sides are, and a balloon only a couple inches inflated is going to be much stronger than a typical size of balloon. It will also have more deflection and less outward force when something touches it, which will absorb impacts. The propeller might even be stopped if it impacted the balloon as it can't support much torque.
If you go much deeper you’ll need an over pressure valve for the balloon. Coming up from 6m you can see how much the balloon inflated. I’m really impressed the only one balloon was able to keep trim so well. Very cool!
Kinda want to see one with an auto-trim feature for depth now. Either via some clever mechanical construction or with some small programmable electronic component monitoring pressure.
I adore these submarine updates. It's always just so neat to see what Incredible thing you've made with basic Lego snap together kit. Truly remarkable.
Great job! It would be nice to install a protective cylinder on the propeller. A propeller with a smaller diameter and more blades can be more efficient.
Great to see your creativity at play! Depth control is indeed difficult to regulate because of the balloon: When the inflated balloon goes up in the water the pressure will reduce, balloon will become larger and therefore adding buoyancy. Same goes for going down, when the inflated balloon goes down in the water the pressure will increase, balloon will become smaller and therefore lowering the buoyancy. It is more an on/off kind of depth control. In Submarines they solved this issue by fixing the size of the buoyency control tank (steel tank) and adding water / removing water. Because of the fixed size of the buoyancy control tank they can have fixed depth control.
See submarine 1.0-used a plastic syringe as ballast. This is more like what scuba divers do with BCDs and drysuits-in that case it works because the diver can react very quickly to changes in bouyancy by controlling their breathing, essentially using their lungs to trim the balloon.
This is awesome. I saw someone printing boats, they used syringes with tubes, connected to a servo arm to act as a ballast. Super simple and genius. Like building subs with legos. Genius.
The innovations from your last two designs are amazing. The magnet system for the propellers is very cool, and the steering mechanism is very creative on this one. The ballast system is incredible as well!
Awwww the fish visited! I love it, this is amazing. So as you’ve noticed, rf control and bodies of water don’t mix… I’m not sure what alternatives you have, but I thought that the magnetic coupling is really elegant
Good alternative: wire controls, like an actual nautical UUV/AUV. At that point he might well need to branch out of legos tho, which is not nearly as hilarious
2:30 the video doesn't comment on that but I think it's cool! You've got enough torque in those magnets to stall the motor instead of getting cogging or having the prop mount fall off. That's kind of a big deal.
A tip for you, the balloon you use to make the submarine go up, can burst if you go up from a deep place, because of the pressure, so try another way to go up, I just don't know another way but it's the best😂
Very cool. I’m going to show this to my physics students when covering buoyancy. Just a suggestion, but what about adding lateral fins to help control stability and depth while moving forward? Keep up the awesome work.
Awesome! This captain found himself stranded at the water floor, face to face with a sea monster. He'll have quite the story to tell to the others once he will be back in his lego box.
this is insanely cool, im constantly surprised by how innovative yet simple you manage to make things, and how you present it all in these videos is like the cherry on top :D
I love how the fish was checking out the sub and even when it started inflating the balloon it didn’t swim away. That’s one fearless fish.

@@AVerySexuallyDeviantOrange I mean the container itself isn’t lego so he might as well, plus the wire can be used for recovery
Timestamp?
Why is this submarine and the remote giving me flashbacks
2:30 the video doesn't comment on that but I think it's cool! You've got enough torque in those magnets to stall the motor instead of getting cogging or having the prop mount fall off. That's kind of a big deal.
This is amazing. It was funny when fish start checking this thing out.
Can you make a lego windwheel that generates electricity?
@Not Zoro now I really want to see a Lego hydroelectric dam.
A tip for you, the balloon you use to make the submarine go up, can burst if you go up from a deep place, because of the pressure, so try another way to go up, I just don't know another way but it's the best😂
Very cool. I’m going to show this to my physics students when covering buoyancy. Just a suggestion, but what about adding lateral fins to help control stability and depth while moving forward? Keep up the awesome work.
I am 99.9% positive this is the coolest thing I've yet to see on UA-cam.
You should check out some of the United States Navy submarines
@@codyevans8554 I wish I had the privilege.
Honor, duty... Top secret... Freedom?
Imagine his that's like you're father and as a kid you do these cool experiments

Awesome! This captain found himself stranded at the water floor, face to face with a sea monster. He'll have quite the story to tell to the others once he will be back in his lego box.
This genius. I want to build stuff for a job when I am older. I like building things. Great channel.

i feel your pain man
Hey, you found my bike, 10:40 was wondering where i'd left the thing!
That Perch is gorgeous. Certainly shows why Izaak Walton describes them as "warriors" in his 1653 book "The Compleat Angler".
this is insanely cool, im constantly surprised by how innovative yet simple you manage to make things, and how you present it all in these videos is like the cherry on top :D
When you used "+" and "-" to show magnet polarity, at least 10 physics teachers died XD
i understood it but I didn't noticed what was wrong ... lol and i am studying for mechanical engineering....
@@redwing6863 for magnets it is usually used N/S instead of +/-
@@redwing6863 I am also studying mechanical engineering, may the force be with us ahahah
@@joaobarros3312 same, guess this video attracted a lot of mechanical engineers huh
Actually, its not uncommon to refer to magnets by +/- orientation, where N=+ and S= -
It’s really nice watching you put these together
The sounds of the pieces clicking together is very satisfying.
Mind blowingly advanced magnetically coupled shaft. brilliant
Universal joint based thrust vectoring???? OMG this channel deserves more views
11:36 Man, that would be sad, glad you got it back
It's amazing!! Love how the fish got curious 😂
Easily one of the coolest channel’s here on UA-cam.
One day we’re all gonna get in trouble using one of these lol
Man one like isn't enough for this job.That's amazing.
