LEGO Technic crane explores deep chasm cave entrance.

On the slopes of Mt Hymmetos lay various caves and chasms. One of the most renowned is the Asteriou Monastery chasm cave, which consists of three chambers. The entrance to the first and largest chamber is a small crack in the rocks about 1.5 meters long and 0.5 meters wide. After this crack comes a sheer drop of more than 20 meters to the bottom of the chamber. As a first step to exploring this cave, I designed and built a small mobile crane to lower a bright LED light and action camera through its entrance. The second step will be to design a bigger crane capable of lowering a small and lightweight vehicle to further explore the first chamber of that cave! Stay tuned for more and enjoy!
Cave exploration crane specs :

I'm glad you did a mission recap. Because I would have been disappointed otherwise. Yes please continue developing this project to reach the bottom! You will regret it more if you don't try, than to try and lose your vehicle, light and camera. Hope to see the next video on this adventure soon!

[@brickandgear]

I am actually in the pre-design process of the vehicle that will descend in the cave. I'm brainstorming on a vehicle that will use a belt to rappel to the bottom of the cave. No winch-breaking or rope-snapping to worry about. Just drop a 30 meter long belt in the cave and have the vehicle rappel down.

[@YourFriendlyOfficeAssistant]

Suspension looks a lot like the Churchill tank during the Second World War. There are rubber studs that you can put on LEGO tracks to give more traction. Had you considered doing this?

[@brickandgear]

I've seen those rubber pads but haven't got any. I don't know if they would work well outdoors though. Some of them would probably get pulled out of place and end up getting lost.

[@BrooksMoses]

@@brickandgear : For real tracked vehicles, rubber pads seem mostly useful on things like smooth concrete. I wonder if something almost the opposite, like putting "teeth" on the tracks, would work. I could imagine putting pins through the holes in the ends of the 5-wide track segments, or even pinning a piece to them, but only one every second or third segment so that there are gaps that can sort of hook around small rocks or projections.

[@brickandgear]

@brooksmoses I tried placing black pins on the tracks in the past (before starting my channel). It worked pretty well and the cost of damaging just some pins is acceptable. You think I should start using them again?

You know I know that in Japan the people would have images of dragons and with your skills and intellect you could make a dragon that would be kinda cool to see a dragon walking on the ground

[@CaptianGhosty]

This is what we live for

[@brickandgear]

I'm definitely doing a Part - II. Imagine lowering a vehicle down there...

[@user-ie3iz3wj2h]

Bro it must take so much effort to do this this video is so cool 😲 keep making these cool videos

[@brickandgear]

Unfortunately, my latest projects took a lot of time. I'm getting used to building "proper" RC vehicles that can cope with the elements, but I'm getting there!

[@JS-yg1jx]

Great job😮😮😊

[@brickandgear]

Thank you! I am currently developing the next vehicle that will probably go down all the way to the bottom of the cave!

Здравствуйте! Я обычный пацан из Казахстана, и хочу вам сказать, вы большой молодец, респект вам!! 👍 Я удивлен тем что вам удается строить, и это круто! Желаю вам успехов, вить правда вам скажу, вы создаете очень крутые вещи :D *Продолжайте в том же духе!* Hello! I am an ordinary kid from Kazakhstan, and I want to tell you, you are a great fellow, respect to you!! 👍 I'm surprised that you manage to build, and it's cool! I wish you success, I'll tell you the truth, you create very cool things :D *Keep up the good work!*

[@brickandgear]

Hello! I am an ordinary guy from Greece! Thank you for visiting my channel! Hopefully, I can visit Kazakhstan in the future and bring one of my boats to Lake Kaindy!

[@ranban71]

@@brickandgear Okay, this will be very cool!!

[@ranban71]

by the way, the idea of lowering some kind of machine on a winch is a really cool idea!!!

[@brickandgear]

It'll need a lot of R&D but if it works, it'll be really cool to watch footage from a 30 meter deep cave!

[@vert2552]

One more thing i would try to do is to make a rotor (slash gear) on the botom to at least look around. You could get it done remotly but it would be heavy, but you could also add another, 3rd, 'rope' to use basic spool to turn the camera with relativly not much added weight on the head

[@brickandgear]

I will definitely install a servo to turn the camera in my next vehicle. I am currently in the "thought process" to start designing the vehicle that will descend in the cave using a belt to rappel to the bottom. Very excited for that project!

[@vert2552]

@@brickandgear Cant wait to see more! :D

[@callmevbuck4054]

If it can go through rocky terrain, its capable enough to travel the entire horizontal length of Texas. Just make sure it doesn’t get lost. P.S, how long did it take you to wind up all that rope?

[@brickandgear]

It took a few minutes. I used a gear ratio that would lower the camera as fast as possible because the Action 2 overheats after about 20 minutes of 2.7K recording.

[@callmevbuck4054]

Fair enough.@@brickandgear

[@cozsmirk7749]

Good job bro I like the designe

[@brickandgear]

Thank you! 🙏

[@charliemudd8063]

a good first attempt, i look forward to a possible followup. in the brief shot around 7:08, showing us how the shape of the chasm was preventing you from lowering the camera & light further, it was difficult to see how close the string was to the walls of the chasm. i was wondering if, instead of a fixed length boom, an extendable boom like the ones seen in sets 42009 or 42082, would be helpful in maneuvering the camera & light pass the irregular walls? also, the summary at the end of the video was a good inclusion.

[@brickandgear]

For my second attempt I am designing a small vehicle that will rappel down the chasm just like a climber. As a third step, I'll probably design a heavy crane (not portable) that will bring the vehicle back up.

Who?!?!? 😁

[@justinmochi7323]

I think more autonomy would be cool. A camera on the crane itself so you could steer remotely like on the ship would be cool, as well as rc controls for the boom and maybe incorporate outriggers! Possibilities with this are endless i wish you luck

[@brickandgear]

Thank you!!!

[@user-vs5mt3wf6q]

Cool

Thank you!

[@Kraftedwiki]

I wonder if a mini gyro stabilizer would help keep the phone steady. There has to be a youtube video to diy one by now right?

[@brickandgear]

I use a gimbal.

[@shanemyself9681]

What were those weird letters on the map at the beginning?

[@brickandgear]

It's Greek.

[@shanemyself9681]

Oh I thought it was Russian or Ukrainian or something similar thanks

[@brickandgear]

@@shanemyself9681 the Cyrillic alphabet was based on the Greek alphabet, so you'll find a lot of similarities between them.

[@MarijnRoorda]

Meh, you made a crane.. At this point i would have come to expect an Ai controlled robot that lowers itself from a overhung bridge and able to steer itself away from ledges with its many claws. Naturally, all made from Lego's.

[@brickandgear]

I could also build a B.A.S.E. jumping robot that deploys its parachute three meters from the bottom and crashes spectacularly spreading thousands of LEGO pieces in the cave...

[@MarijnRoorda]

@@brickandgear That would be awful. Just seeing Lego's in the environment triggers some weird response in my brain. They should be kept in a controlled environment, away from the sun, like your room. They can collect dust, minor insect life, bandaids, that just adds flavor. But throwing Lego's, brightly colored pieces of plastic in a natural environment, almost feels like a crime.

[@brickandgear]

@@MarijnRoorda in the end, they are toys. Toys are meant to be played with, in any environment.

[@MarijnRoorda]

@@brickandgear I do agree. However, you can just leave them lying around in your room. However, leaving them in the environment should be refrained from. As a kid my mom made me clean up my room at least once a year, and i never understood why cause then i would have to get all my Lego's out the next day to return to where i was. There was a very careful weeding out process, all my Lego came in several huge crates, you'd throw it out on the floor, and you start searching for parts. Eventually, at the end of my room, all the good parts would end up, (where the giant spaceships would materialize) and the junk ones would stay at the entrance. (A side benefit was that my parents would stay out of my room in fear of stepping on Lego's.) You can't very well exhibit such behavior in a garden, or a mountaintop.

I just realized that there is Barb wire. This is so much safer🏗

[@NorthTo60]

I'm just saying that your life is more important than the camera feed👍

[@brickandgear]

Even with the cover, I kept a safe distance from the entrance. Even when I shot the entrance from above, I used a tripod to extend my reach.
