Building a Lego-powered Submarine 4.0 - automatic depth control
Переглядів 21,490,181
День томуThis radio-controlled submarine can maintain a steady depth or a certain distance from the bottom. It is equipped with a pressure sensor and a laser distance sensor. Raspberry Pi and PID control are used for automation. Tested in a swimming pool and a small river (at the end of the video). Enjoy!

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.

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.

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?

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.

I think he started the channel while in highschool or maybe earlier. He is probably a couple years into his undergraduate education by now. I am assuming he chooses major projects that can be used for college credit, and then be turned into a video for the channel.

That underwater footage was incredible! Would love to see in in full length and real time!!

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!
@josephdavis2695 Рік тому
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.

Stupid me thinking I could have been the first one with jokes about the billionaires.

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.
@eastoforion Рік тому
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 :)

This video needs to be shown to students during the first week of Introduction to Mechanical Engineering. Very nice job!! I was particularly impressed with the depth control.

bro's homemade sub is better than the one that billionaires used💀
