All the movements in this layout are operated by the motors installed in the trains. Microcomputers or electronic control devices are not used in this system. More information and instructions: akiyuki.jp/en/works/1019
3:28 Imagine being the guy who proposed this section. "Yeah, I know we can detach the container and tip it to let the cargo out, but... hear me out... what if we _flipped the entire car over_ instead?" "What, so we have a crane or something to pick it up off the track and flip it?" "No, no... the track flips too, that's way easier."
Actually it is way easier. Trying to get it back on the track after picking it up is much harder than holding the car down and flipping the whole thing.
I just had a look at the link in the description. The professionalism and the clarity on your website is astounding, and the fact that you provide building instructions for each and every module seen in this video just blows my mind. Hats off to you!
Totally amazing. It's awesome that you have a system with three cars on the same track system, with every part of the process powered BY those cars. I do wish the fourth car were also part of the same track system (And identical in form to the other three cars), but that doesn't lessen anything I'm seeing here!
Bringing it all together and amazing! You are definitely 'on track' with sharing your latest creations Akiyuki-san, please keep on going with sharing (with more balls).
Awesome build/creation indeed! The precision, mechanism and timing of this train system is well thought of. The generosity of sharing the instructions is the cherry on top of this model. Kuddos to you Akiyuky and more power!
Once again, the genius level of this is insane. Just want to point it out again for everyone who doesn't get it: There are only the driving motors inside the cars!
Just wow, you are really THE Master of Lego Great Ball Contraption. I love your design style, it looks clean and simple (I know it isn't) and works so well!!!
It's hard to pick the best part: I like the custom tight curve, the colour-blocking, and the superb job with the presentation (all of the previous videos). Truly a work of engineering and art.
It is a wonderful and ingenious mechanical system. This layout is rather complex but it is nice that Akiyuki published a whole series of videos. Even if you build just the basic setup (that presented in the introductory video), you will still see and learn the main mechanical/control principles and enjoy the vow effect. And than you can decide whether you will go on with more advanced modules.
Wow, akiyuky! That was amazing! I really like this layout, and all of the automated functioning ore cars. It was like the most satisfying video in the world, but with LEGO Mindstorms. The part that I appreciate the most is the usage of the narrow gauge train tracks to make a tighter curve for the ore cars. That's just pure generous! Complements from cheeseinthepie. 4/2/2018
Wow that is insane!!! The layout is well thought, there is no crash, and all the cars follow a path that is pretty long, except ont cart😅 thats so awesome, you are very talented. Wonder if GBCs are ever gonna get better than this, because all of that works with just 4 motors and it’s so well designed. Incredible work!!!
I love how all the mechanisms are powered by the cars themselves. Gives me some ideas of how this could be applied to cargo ships, with the cranes on the dock powered directly from the ship, which has its engine running anyway.
I think this has the potential to have the train go around the gbc layout and add ball counters along the way. Then add an nxt to the system to monitor where all the balls are and have the train deliver extra balls to places that have a low count.
I wish I had the pieces to make this It’s so amazing and I love building lego train and watching great ball contraption videos so this is perfect for me
you did it, a closed-loop feedback system, yay! nice demo with the soccer ball marble have you run it long enough to tell what number of marbles are transported after many repeats? erm.. the steady-state delivery rate of the closed-loop system? LOL ty for posting! : )
That’s incredible! I remember when you had just the regular loader, the crane loader, the tipping unloader, and the switch. Now you have redesigned versions of the loader and unloader, as well as a new unloader, switch, and double switch system! Wow! 2018 is gonna be the best year ever!
watching all the different parts over the last few weeks and then seeing them all come together like this is brilliant. absolutely brilliant. i do have a question though. How many "trains" can the system run? is that the maximum you have shown here or is there scope for more on the current layout?
That is the main limitation. It needs reconfiguration to support other counts of wagons. The corner circuit can have only one wagon, since it does a full reversal and has no meeting points. This applies from the central meeting point to the blue loop as well. And both the central and end stop meeting points require two wagons to operate, so all three wagons are necessary to avoid deadlock. A full loop type system (no bidirectional tracks) could handle larger variety in wagon count, or having a queuing module (that would permit more than one waiting wagon). If the meeting points were reconfigured to not hold until the second wagon comes in, that part could operate with fewer wagons. On the other hand, each wagon is autonomous so they can simply be swapped out, as long as this is done without setting them up for collisions.
LoneTech thank you for that. I see now any additional vehicles will be limited by the amounts of passing points. Your explanation was most insightful thank you
Impressive! I don't know if the following is your final plan, but I get the intuition that you now have the building blocks to creating a Turing-complete system!
Lovely. Next step : Is it possible to use metal rails and electrify them? Practically speaking, the batteries driving all aspects is the only issue here.
