[TC10] Pneumatic lift [GBC] module
Captainowie posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi. With the quality of entries I've seen so far, I don't like my chances of winning, but it would be nice to get a badge! I'm going to use this contest as an excuse to redo a previous model of mine - a GBC module powered by pneumatics. This is what the old version looked like: I have used it in a previous display, but it has numerous shortcomings as a GBC module. The output is not in line with the input, violating the spec. It was what I needed at the time, but it's not suitable for general use. The output is impolitely high. Again, it was what I needed at the time, but I couldn't put this into a normal circuit. It would frequently jam. It spilled lots of balls. I will be using the same sequencing (basically the simplest alternating sequence possible). I had toyed with the idea of something more complicated, but 1) I couldn't get my head around how to make the sequence I wanted, and 2) it would have been too slow anyway. I probably won't make a compressor for this one, leaving it hand-operated. The idea being that in a display it can be somewhat interactive - the audience gets to power the Contraption (or at least some portion of it). Best of luck to all entrants! Owen. -
[TC10] Metsjö Pneumatic High-Tip Trailer
Klirre posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi! This is my first topic on the forum, I would probably not have posted at all if it weren't for the pneumatic contest. A combination of me seeing the 42053 EW160 and finding my old lego technic from late 90's and early 00's led me to this forum filled with nice people playing with arguably the most versatile toy ever. I'm a trained mechanical engineer, though not practicing my trade yet, and looking back I believe Lego Technic was one of the big inspirations that made me choose that career path. Back in the day I had (and still have) a 8459 pneumatic wheel loader, and now I was leaning towards buying the 42053 EW160. But why not test my skills (and luck?) by making a nice little MOC for the contest. Enough drivel about the good old days, over to what I've come up with so far. Please bear with me, I am aware that you guys are way better at this, have more parts at home etc. The point of this project was to make something that I actually wanted for my already existing sets without costing a fortune for me to buy and build. It's a trailer suitable for both the 8459 and 42053, inspired by the Swedish-made trailers from Metsjö. I wanted it to be more than just a regular trailer with tipping function, so I'm aiming for a two-step high tip function which raises the rear of the bed before tipping it. The tailgate is automatically opening and closing with the tipping, thanks to a lever on each side which are connected to the frame. The final "function", so far, is a parking support in the front. This is what I've come up with so far, I must say that LDD is really bad when you want to try the functionality of your model. I still haven't figured out how to make the pneumatic circuit work as intended. The goal is to put the main switch on the Digger/Loader/Tractor pulling the trailer, leaving the two-step function automated and built into the trailer. So when you pull the lever to tip your load, it first lifts the rear, then tips. I'm hoping that my old friends, the laws of physics, will solve this for me without the need of two extra switches on board to route the air, but I suspect that Murphy's law will decide my fate in the end. So what do you guys think? Too simple and easy? Too predictable? Put on a LA and paint it gray and you'll end up with half an Arocs? Awesome? Improvements? Other ideas? If the feedback is good enough I'll just have to convince my bank account that I need to make an "investment" or two on bricklink to build it IRL. There's still a lot of things that needs testing which is not possible in LDD, so I'm a bit scared that I will have bought a bunch of bricks that won't work... metsjo-trailer.lxf -
[TC10] Tracked Dumper with Crane
ScaleCarModels posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Here is my entry into the contest a tracked dumper with crane. Based off a Morooka/Terramac style crawler carrier platform. Planned Features - Pneumatic Dump Bed - Pneumatic Crane - Detailed Track System - Detailed Cab/Engine Compartment - Pneumatic Pump driven by M-Motor Build Progress Here are some photos of the undercarriage: The dump platform is based off the MB Arocs, but will be further modded to fit this build. Here is a mock up of the crane, based off MB Arocs/effermanns modded design. This will be changed almost completely since it is too large. The crane and dump section need to be redone since they copy an already built design. I just wanted to see how scale and function would work on the tracks. The track design took me a while to figure out since this is my first creation in Technic. I want it to be somewhat modular to help with installing Pneumatics. More to come... -

[TC10] Heavy Lift Telehandler
luukietechnic posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Helly everybody, Here is my discussion topic for the TC10 contest. I have made a Heavy Lift Telehandler. I almost finished the model, but I will show the progress in steps. In this first post I will show you the chassis of the model. On this photo you can see the chassis with a box where the boom is going to twist. There are also two big v2 pneumatic cylinders to lift the boom. On the second photo you can see how I made the motor with a pneumatic pump. It was hard to fit both the motor and the pump horizontaly . If you have any tips or questions please post them here. This is the first time I'm making photos in this way, so if they are not so good give me some tips how I can improve the quality. I will soon give you an update of my build. ps: the stickers on the rear 7 beams are there because I haven't enough of these beams at the moment. Later you won't see these any more, because the boom is in there. -

[tc10] pneumatic bumpercars
matth posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello, here I am with my object for this contest, made myself a crashcars slash bumpercars, completly like in reality for transport, just 2 mm space between the trailer and wheelpart to get it out, then lowering and start building... I use the pumps instead of a cyllinderenginepump, duo the weigt of the roof when open...is some weight on it, with 2 handpumps it goes faster.. the cyllinders you see are real lego technic but I bought them chromed at Aurimax at bricklink duo the fact that yellow is not my kind of colour and would be horrible to see in my bumpercars, I put a picture of it with the normal ones so you guys can witness it... so it contains: 4 cyllinders 4 cyllinder brackets 2 pneumatic switches 2 handpumps everything (exept the net offcourse) is lego, no fake lepin or 3th partiebricks... I just made a purple rooftop on it to be realstic, I'm breaking it off today so I will make a movie and post it tomorrow then on the entry forum, hope you guys like it,I know funfair is always a risky subject duo everyone making trucks and cranes... So I ope atleast someone enjoys it.. cheers http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439666 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439668 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439667 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439669 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439670 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439674 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439672 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439673 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439675 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439677 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439679 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439680 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439681 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439682 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439683 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439685 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439686 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439687 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439688 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439689 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439690 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439691 picture of the chromed vs normal cyllinders... http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439692 bussy with my roof.. http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439698 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439696 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439697 close up from the cyllinders and from the engineview with handpumps http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439693 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439694 http://www.brickshelf.com/cgi-bin/gallery.cgi?i=6439695 -

[TC10] Snow Groomer
Wiseman_2 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi everyone, I figured I'd have a bash at this contest, so here's my entry: I decided to go with a Snow Groomer for this. It has six pneumatically powered functions, along with manually driven tracks: Raising and lowering of the front blade Tilting left and right of the front blade Adjust the front blade's wings Raising and lowering of the front end of the vehicle's undercarriage Raising and lowering of the rear tilling blade Raising and lowering of the tilling blade's smoothing plates and rollers All controls for these functions are in the rear bed. I opted for a manual pump rather than a motorized one, as the contest is, after all, pneumatically focused. All photos are on my Flickr, but I'm going to post them all here anyway as I doubt everybody will see them there. With front and rear blades lowered: With the front blade angled and the wings adjusted, and close in detail: With the front end of the undercarriage raised: And finally the detail of the rear blade: I'm currently in the process of putting together the video for this, hopefully should be ready in time for the deadline -
[TC10] Pneumatic Rock Loader
KirTech LAB posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi! Today I’d like to present new model designed special for Pneumatic contest. It is heavy Rock Loader. At first I wanted to create tracked chassis but the final version is wheel-based. Transport dimensions: 88 x 25 x 27 cm, total weight – 5 kg (four large BBs in the tower are used as a counterweight). The model has no motors :) In the rear part of the model you can see eight pneumatic valves: - Clearance adjustment, left and right independent (six large cylinders); - Outriggers deployment (four small 11L cylinders); - Outriggers (eight large cylinders); - Superstructure rotation (+-90 degrees, two large cylinders); - Boom lifting (two large 11L cylinders); - Boom extension (two large 11L cylinders); - Bucket unloading (two large cylinders). Here you can see detailed video demonstration: Also the model has a few mechanical functions: - Independent suspension; - 4x6 normal steering; - 6x6 crab steering; - bucket self-leveling system (a lot of gears on the boom :)); - Expander (four large pumps). Detailed photos you can find on my Flickr page: https://www.flickr.com/photos/141718063@N06/albums/72157675577609735 Thanks for watching! I hope you like it :) -
[TC10] Pneumatic Walker
trekman posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I present to you my effort in this competition. This will be a pneumatic walker, powered by a separate compressor. There will be a supply going to the pneumatic valves. These will create a sequence of eight movements at four cylinders, which should be enough to lift the legs and tilt the lower body. This is very much at development stage and will be added to until the deadline. I have a nice selection of pneumatics, which makes this contest quite appealing. -

[TC10] Side Loader Garbage Truck
paave posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
My entry for the contest is a Side Loader Garbage Truck, based on KO-440 (GAZ-3309 chassis): Features & Functions: HOG steering Flat-2 engine Opening hood Container lift Container tilt Dumping Opening tailgate It was a real trouble to make dump function work. It only allows to set a thin long cylinder, which is not enough to lift much. For the contest I left it that way, but generally it’s perfect with the small linear actuator; in the video I show both versions. Video: -
[MOC][WIP] DuraStar Tow Truck
Thirdwigg posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I am in a little bit of a creative lull right now, so I decided I needed to make something small and quick. I very much enjoyed doing the quick build of the 911 I did earlier this year. There was something enjoyable about posting nightly, and watching how something comes together in the course of a week or two. Plus the feedback was enjoyable and contributed to a better MOC. So I decided to do a small tow truck: an International DuraStar. Since I have spent so much money on many pneumatic parts, but find myself decidedly in the Linear Actuator camp, I figured a MOC with pneumatics would be a good challenge. The MOC will feature: Steering Drive Fake motor Winch Crane Crane extension Car lift Final colors will be yellow with blue highlights. Here is the first WIP picture, and more will be posted nightly (roughly). Here we go! -
[TC10] Little Bulldozer
Appie posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Had some inspiration to build another little pneumatic model after thinking of my little wheel loader that I build a couple of years ago. They aren't the same scale, because I was going for a look where the small pumps look "big" on the bulldozer. So this is smaller. Functions: - Blade up/down with pneumatics - Plow up/down with pneumatics - Mini V4 engine with differential A little video: Some more pics: I wanted to use that panel for the front blade, because I think it suits it. Decided to add a little grey line to fit with the sides and break up an otherwise very yellow blade In this photo of the side you can also see the blue "chair" (2L pin joiner) that I use to contol the pump below the "chair". The blue hose above the engine is from the pump. I tried to hide the switches at the rear as much as I could, while still being easy to access. Next photo a little more up close: Used Lego's colour coding for the pneumatic hoses. Plow ready for some lifting action. Or to actually plow... You probably wonder why on earth did I want a diff in there? Well I wondered that myself as well actually a couple of time during the build, but the real life versions got it, so why not this It sure provided a fun challenge to route all those hoses around it. It's very snug, but nothing touches the gears or the engine. Thanks for watching. -
My idea for this contest is a pneumatic carousel. I never work with pneumatic before and I was not sure if it would even work. After going though so many prototype I finally have something to post. Here is my progress so far. Pneumatic is a lot more challenging than I thought.
-
I'd like to show you my progress on my pneumatic tank. It includes the following functions: Driving Rotating of turret Shooting Barrel adjustment Both tracks can be controlled separately. I used gearracks to transform the linear motion into rotation to drive the tracks. I used a combination of gears to allow the tracks to move forward by extending and contraction of the cylinders. Therefore it is ony possible to drive forward. I limited the rotation of the turret by a 90 degrees to the left and 90 degrees to the right. This allows for the hoses to go through the turntable. The shooting mechanism shoot when the cylinders extend, and when the retract. This allows for relatively fast shooting. Do you have any suggestions what can be added or improved, just let me know.

[TC10] AT-AT
Jeroen Ottens posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi, Here is my progress so far on my attempted entry for the pneumatic challenge: I am trying to build an AT-AT walker, but is proving to be very, very challenging ... The mess of tubes inside the structure are part of the pneumatic sequencer that control the legs. For each leg four phases are defined: 1) Whole leg backwards 2) Bend knee to lift lower leg 3) Move leg forward & straighten knee 4) Move straight leg backwards The four legs are kept out of phase with each other to keep at east two legs straight at all times (either forward or backwards). In fact the sequence is not ideal, since 2 out of the 4 phases have a leg in the air (2+3), while idealy only one phase should have a leg in the air because then there are always 3 legs supporting the weight. What definitely not helps is the hopelessly high center of gravity combined with a ridiculous small base for the feet. With a manual pump I can make the whole assembly walk to some degree (well, walk, let's call it stumbling forward), but after a few steps it usually topples over sideways. When I add the batterybox and a small pump it doesn't even move the legs when I lift the model in the air. Apparently one small pump does not build up enough pressure... So, decision time... Option 1) Continue with the model (I do have some cool ideas for the head still including a simple return to center mechanism for rotating the head ). Solve the pressure issue with either more small pumps or by going manual (saves weight as well) Option 2) Abandon project and go for a six-legged walker (AT-TE) which is much less of a challenge, but has therefor also a much higher chance of actually working in the end. What would be your advice? Jeroen -
[TC10] Unimog U 400
syclone posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Good day! Just instantly got the idea of making a unimog with pneumatic attachments. Functions that will be included: -4x4 -Fake engine with moving pistons -Pneumatic ports on front and rear -Mechanical outputs on front and rear -Attachments using these outputs -Tiltable cabin -The PTO's can be engaged to the drive -Tiltable bed -HOG For now the front axle, has steering and drive. Probably will have a pendular suspension on front. I made some more progress, in an hour the images will be, right now can't upload them. LDD file shows the actual progress. I also made a folder on Bricksafe Also I used Sariel's scale tool to get exact dimensions of the model based on the wheels -

[TC10] Caterpillar M315D
KUPOV1 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello everybody, I want to share my new project. I am going to build Caterpillar wheel excavator. Featuring: -4x4 drive -one axle steering -air tank (if it'll be necesarry) -12 pneumatic pistons -7 pneumatic switches -2 small pneumatic pumps -HoG steering Rotating of main boom will be controlled manually. In main boom I will place battery box as counterweight, motor with pumps and fake engine. Trought the main technic turnable actually goes steering (black wheel), gearbox elements will be used for driving fake motor and one pneumatic hose to bottom switches. After three days of work I have got almost completed bottom of excavator and front blade.
