@Jim But we haven't even closed the topic of TC23 entry yet. And there was no voting. Can we finish with the previous contest first?

Space Police is certainly an original idea. But I agree with the opinion that it will be difficult to implement in the style of Lego technic. And everything can turn into a competition of system models. - A modular vehicle would also work well for a Technic theme. - The theme of walkers was once voiced. I would vote for her. - road and municipal vehicles - mechanized animals

I finished the io file. Here is the link: https://drive.google.com/file/d/1e2rA7jDu8wVZO-pmxUOcZG589lcXNZjg/view?usp=share_link I apologize if there are some inaccuracies in it. I don't have much experience yet. I will be glad if it is useful to someone. Also here is a scheme of the main mechanisms: Well, at your request, rear view from the studio:

Unfortunately, I have no experience in creating instructions. And I do not consider my work absolutely finished to make instructions as for a finished product. Yes, it does show some technical mechanics, but it still needs a lot of design work to look good (primarily using lots of studded bricks). I do not have enough of them, so I limited myself to the studless parts. I also made many changes when the main structure was almost ready. Therefore, in order not to do everything all over again and be in time for the competition, I had to make these changes not in the best way. Therefore, for a person who would assemble this model according to the instructions, they would seem strange. But I'll post the .io file when it's finished if it inspires someone to build their own models.

perfect entry for this contest. To be honest, I was not so much impressed by the Ferris wheel itself (although it stands out for its scale), but by the ball feed mechanism. It's just incredible mechanics and yet works so reliably. Excellent result

What a wonderful collection of farm equipment! I especially like that you chose not a very large scale. They are "simple" in the best sense of the word and there is nothing superfluous in their design. Great job. I look forward to updating the collection. And my special thanks for the instructions. I will definitely collect them all when my son is a little older and we will build a fun farm together :)

Serpentine The mechanism pushes the balls up in a zigzag path. One L-motor is used

@Jim Mb it's time to open an entry topic?

You're right. I adjusted the position of the gears many times until I achieved stable operation at all stages Thank you, guys, glad you liked it Now the work is completely finished. At first I was going to remove one downshift 24:8, but then I remembered that I had not charged the batteries for a long time With fresh batteries everything started to work faster and I changed the 24:8 downshift to 20:12. Now I think the speed of work is normal. I also had to strengthen the whole structure a bit, because my 2 year old son showed a lot of interest in this mechanism, so I had to often lower / raise / move it to save it after the game I am posting the final photos and videos:

Thanks Thank you. Yes, it is set approximately so far and any speed can be set. Now done double downgrading 8:24. Before the final video, I will remove one downshift.

The work is done. A ball tray was added (holds approximately 100 balls) and a mechanism for feeding balls to the conveyor. Slightly changed the design of the main mechanism for more emphasis on the main details. One L-motor is used Now the mechanism is made for cyclic operation, but can be configured to serve balls at any distance and height. Here are some preliminary photos and videos of the work.

Hi all. I still decided to take part in this competition, although I had never built GBC mechanisms before and was not even familiar with this direction in LEGO. I hope that I have not accidentally repeated any of the already existing similar mechanisms in GBC and therefore I will not violate the rules of the competition (if a similar one already exists, please tell me). So. The principle of its mechanism is to move the ball in a zigzag pattern from bottom to top. The pusher lifts the ball up at an angle of 45 degrees and when it reaches the top point, another pusher picks it up and the cycle repeats: At the moment, I managed to make several repeating segments of the main mechanism to check its performance. It is necessary to add a couple more of the same segments and design a ball feed tray. Your feedback and comments are welcome.

Wow. In the middle of the competition, when I saw so many wonderful entries, I didn't even hope to get into the medallist. I'm very happy. Thank you for your votes. As others have said, there were so many good entries that it was very difficult to choose just 6. Congratulations @MP LEGO Technic creations and @Thirdwigg, you are very cool! Thanks to @Jim and @Milan for organizing the contest.

Could you share a file with adjustable LA and pneumatic elements? I will be very grateful

Now that I have seen the new photos, this model seems even more incredible to me. Because it looks HUGE when unfolded and I couldn't believe it could fit in a 10,000 box. Amazing!

Welcome to Eurobricks! It's rare to see ships on the Lego Technic forum. And your building looks great and I think it would be very interesting for a child to play with it . Very original use of caterpillars! Did you make this building specifically for the competition? If so, what is the overall size of the box? I could be wrong, but I think it's more than 10,000 studs. If not for the competition, then it is not necessary to add [TC22] in the title of the topic. In any case, I would like to see more photos. Great job!

Thanks for the feedback guys. Yes, "logs" are not quite ordinary . Because if you fully load the claws with heavy wood of great length - it will weigh more than the loader itself. Even with such light logs at full load and with the boom fully extended forward, the machine is on the verge of tipping over. But the cover opens at the back and you can add additional weight for the counterweight (in fact, I held the model not so that it would not turn over from the weight of the load, but in order not to turn it over when the pump was pressed, because the effort required is quite large) You are absolutely right about the restrictions. These are the limitations of the functions of pneumatics, and the tensile strength of Lego parts. Therefore, if I have enough inspiration after the competition, I will make this loader on a larger scale without pneumatics, completely on control +. This is a minimum of 6 functions (7 with pusher slope), so 2 hubs are needed. According to my calculations, this will require a wheel scale no less than the wheel of Zetros. But that will be later...maybe...

Both models look amazing . But at the same time, the excavator has a lot of functions. But it's so hard to make a choice...

Nice, clean design . It was especially interesting for me to watch the construction of the front loader, because this is an alternative appearance of the equipment that I selected for the competition and we have the same scale. Looking forward to the final photos!

I agree that if you go down this path, you will end up with the style of a model team. Of course, this will give the best appearance (I join in the compliments on your trucks - they are beautiful!), but may not comply with the rules of the competition. And at the last moment you may be faced with the need to redo the model. It is better to wait for Jim's answer. But it's a good idea and good use of the technic parts.

It was interesting to watch the progress of this model. Great design, it would fit perfectly in the animated film "Cars"

@jorgeopesi @KevinMD @Thirdwigg @MangaNOID Thanks for your comments. I have medium sized fingers and it is comfortable for me to turn. You can always raise the HOG one stud higher for convenience. But I had to refuse to place additional lights behind the cab, because they interfered with the control. I changed some of the final photos to match the subject of the application. Video is ready. I hope you like it

9. Log loader VOLVO L180HL Functions: Pneumatic control: - boom lift - boom tilt Manual control: - grip rotation - open/close grip - turn (HOG) - slope of the front bumper Model size: 33x12x19 = 7524 studs

Final photos are ready. Video coming soon too
