Φαντάσου και το εξής : Μόλις το όχημα επέστρεψε στην επιφάνεια, αφαίρεσα την action camera και πέρασα όλο το αρχείο της λήψης στο κινητό μου για να δω το αποτέλεσμα. Το πρώτο συναίσθημα ήταν η πλήρης απογοήτευση βλέποντας ότι το μοναδικό που τράβηξε ήταν κοντινό στον τοίχο όσο βάραγε με τα "μούτρα" το όχημα στην σπηλιά. Και ξαφνικά, μετά από 35 δευτερόλεπτα απογοήτευσης, ο θάλαμος ανοίγει και φαίνεται η σπηλιά σε όλο της το μεγαλείο! Υ.Γ. Ο βράχος που είναι σαν πρόσωπο, σε ποιο σημείο φαίνεται;

Is that ship accessible by divers? It would make a cool future project! As long as the channel grows enough to pay for plane tickets to Brazil...

In the future, I'd like to build a bigger version and shoot a video of it being loaded with cargo using a crane and my old LEGO 9V train.

Thank you!

That would be super cool, but unfortunately the Titanic is too expensive for my current budget. Maybe in the future!

Fun fact, the plane probably crashed further away from shore, but was accidentally carried closer to the shore by fishing trawlers. During that process, it was broken into several pieces, some of which have yet to be discovered.

Thank you! You never know what you can build unless you start small. Check out how I started building ships, and you'll get the idea : czcams.com/video/l8U77MbwlgI/video.html

I'll need a huge drone for that!

There's a reading on my controller that displays the signal quality as an error percentage. If the reading is too high, I'll bring it closer to avoid loosing connection. In case of any other failure, I always carry a small inflatable boat with me for recovery.

You can actually see it in the building process part of the video. I shot it after completing the mission. If you look closely you might notice there's dirt on the tires, although I cleaned them up before shooting the video.

Thank you!

Glad to see you're back to see part two! This mission opens up possibilities for many more projects, as the rappelling system seems to be able to lift a lot of weight (with the right gearbox of course). Definitely expect to see a small vehicle rappelling down a cave, and further exploring using tracks or tires to move around at the bottom. I'll need an FPV system to achieve that though, as I'll have to see where the vehicle is going. The comments always help to further brainstorm on any problem. The comment section actually inspired me to use a retractable cord to measure the depth of the cave and monitor the position of the vehicle to avoid smashing on the bottom at full speed.

@@brickandgear has anyone else explored the cave in recent times? What has prompted you to explore this particular cave?

@@EVP22 it's very popular among cave climbers for training reasons. Very accessible, with a good total depth and it is 100% mapped. Fun, but grim, fact during the first exploration of the third chamber, two human skeletons were discovered dating from the 1800s. A clear sign that there was another entrance to the third chamber that collapsed when the two humans were inside. I visited the entrance to that cave, as well as many others on that mountain, when I was a student riding my mountain bike. I was always fascinated by deep cave systems, high mountains, and all sorts of exploring so I decided to bring my LEGO into the adventure! Now I need to convince Elon Musk to launch one of my vehicles to the moon...

Thank you!

Best crane in the known universe!

No, not yet.

Why?

I was thinking about building something that could climb an old industrial chimney, but they are too wide...

Huh too bad lego treads can use suction cups or at least use a gargling hook

Thank you! 🙏 I'm glad you enjoyed it!

😁

Thank you!

😁

It's a propeller for RC boats. Suitable mainly for tugboats.I got it from a store in Athens that sells RC stuff.

@@brickandgear thanks

I'd never let my camera get damaged. The LED light at the bottom and the wheels on top took all the beating! 😁

I tried to keep it as light as possible, otherwise it wouldn't be able to climb back up again. I can't wait for part III as well, but I can't do it yet. I'll need to build an FPV system first, as I'll need to see what the vehicle sees down there.

@@brickandgear You could try doing it with a crane to pull it up instead of it pulling itself up also I don’t know if this would work but maybe use multiple cranes that lowers it down and uses and electromagnet to connect to it but it would have to be really strong to do that without disconnecting when hitting stuff and since it seems to mostly be a really wide chasm you could probably make a crane that is stationary but and moves but you would have to get rid of the fencing over it and if it gets stuck you wouldn’t have to push the rope and also since there is probably terrain it would get stuck on I think you should add tracks and a secondary crane that isn’t Lego to pull it out in case of emergency that has a way longer rope and Is connected too the build securely so it can be pulled without the worry of it falling off

@@Ayers-dog-lover I used a crane during my first attempt. The problem with the crane is building a winch that can handle a huge amount of pressure that builds up as the rope gets wrapped around the winch axle. Wrapping 25 meters of rope stresses the build very much and it's prone to structural failure, as axles tend to bend under the immense load. So, for such a depth, using a belt and rappelling system was much easier. Then comes the rate of descent/ascent. A winch has a much lower rate of descent/ascent and my DJI Anton 2 camera can only record 15 minutes of 2.7K video before overheating and shutting itself down. So, it would probably shut down before it resurfaced. With the rappelling system, the vehicle went down almost 25 meters and back up again in under 5 minutes! Your electromagnet idea is amazing! A fantastic system to lower a small vehicle and release it once it reaches the bottom! I'll have to brainstorm on it!

It crashes. I build something to locate it. It succeeds... then crashes. I build something to retrieve both vehicles... It crashes trying... I shut down the channel... 😆

I tried to balance the vehicle so that it tilts a bit forward, to protect the camera from smashing on the rocks and help the vehicle to overcome any obstacles during the accent by using the wheels on top. It came back up, so I guess it worked 😁. I would like to build a cheap FPV system in the future though. It's very important to be able to see where the vehicle is going, be it a ship, land vehicle, or anything else.

There's nothing that cannot be done using LEGO. Give me a few years (and a big rocket) and I'll land a LEGO rover on the moon...

Yes, they are LEGO.

Thank you!

Send me a picture of the completed boat on Instagram or via e-mail whenever you complete it! I always enjoy people getting inspired by my builds and building their own vehicles. Unfortunately, the propellers, servo motor, battery and electronics are not LEGO, so there are no part numbers.

Good luck with your Titanic project! What help do you need?

Ευχαριστώ!
