Lego Rock Rod - Buwizz powered crawler
filsawgood posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi to all fans of Lego! Today I want to share with you my new work - Rock Rod Rock Rod - it's the crawler, on the construction of which I was inspired by the fierce custom projects from HAUK Designs. Especially, where, no matter how on the crawler to run a fresh RC DC chequered flag STT PRO rubber wheels and BuWizz. At the output was a relatively light on the portal bridges crawler. At the heart of the model is also the philosophy of placing motors on bridges, to reduce the center of gravity and minimize weight and inertia of the body. Technical characteristics of the model: Weight (together with a technic-figure) - 817 g. Number of parts - 617 pcs. Steering - Servo motor Movement - two L motors Power / Control - BuWizz Even the "sofa" trial allows us to understand that additions such as non-standard tires and BuWizz significantly expand the scope of use and possibilities of radio controlled Lego models. It remains to wait until the snow comes down, to ride Rock Rod on the rocks. But you can do this before me, by building the Rock Rod yourself by free video instruction. I plan to test the model in the spring on a severe off-road. I will be very glad to hear from you any advice or wish for the completion of both the technical component of the model and its appearance. Ahead is still half a year :) -

[MOC] Jeep Mighty FC Concept
Madoca 1977 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello! My latest MOC is a re-creation of unusual Jeep model. Jeep Mighty FC Concept -Weight: 2125g -2 XL motors for propulsion -Servo motor for steering -M motor for 2 speed gearbox -M motor for locking rear differential -M motor for winch -3 LEDs for front and rear lights -2 SBricks powered by one rechargeable battery box -Portal axles -Openable doors and tailgate -Shallow bed with fold-down sides -Detachable roof -Alternative tube doors The chassis is not realistic, but has decent offroad capability as heavy Lego model. My goal was to make a sturdy and powerful crawler having propulsion motors and gearbox on the center of its chassis. Which means the drivetrain contains two universal joints - weakest points - for transmitting the torque to front and rear live axles. To save U-joints from damaging, I adopted two stage reductions after differential on both axles. The gearbox is similar one to my previous FJ40 Crawler. I doubled the pair of 8T/24T gear for higher durability. High gear is three times faster than low gear. You may wonder why rear ball joint is connected lower than front. That is for avoiding body roll caused by high torque of hard-coupled XL motors. Seeing from the gearbox, the rear output rotates in opposite direction to the front one. So the front and rear axle are equally forced to rotate in opposite direction to each other. Thus the center chassis with heavy body does not easily roll left or right even when climbing steep incline. (...at least on paper. I admit the complete body is a little bit too heavy to prove the theory above.) Steering angle is good, but turning radius is not so good. Because of the lack of center differential, it cannot handle different rotating speed of front and rear axle in tight turning. On slippy surface, like in the video, it can be steered without any problem. Rear differential can be locked instantaneously. The role of 8T gear on top of red changeover part is to make a tiny gap between 16T clutch gear and driving ring in locked position. Thanks to the gap, 16T gear is not pushed against outer structure. That helps to decreasing the friction. Front winch is powered by M motor geared 9:1. I used two pairs of 8T/24T gear instead of worm gear. It is smoother and surprisingly powerful. The hook can be manually pulled out by switching the lever under right seat. The body looks a bit squarish comparing to the real Mighty FC. Maybe I could replicate trapezoidal shape of its cabin. But I thought angled pillars and roll cage would be wobbly. So I decided to build simple yet sturdy. Instead of realistic appearance, I managed to realize easily detachable roof and doors. Although the whole MOC is built for using Unimog tires, Claas tires also fit well. But the maximum articulation of axles would be smaller because bigger tires possibly touch the chassis and fenders. It would be necessary to limit suspension travel or slightly modify the chassis. I hope you will like it! I will make building instruction. But I have to finish the instruction of Pickup first. -
[MOC] 4x4 Crawler with winch- based on 1960/70 pickups
BrickbyBrickTechnic posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
My latest MOC, the 4x4 crawler! This was modeled off some 1960/70 pickups, hence it’s boxy look. The goal was to have a powerful drive and a winch, with a release like in 42069 so it can be pulled by hand then engaged. I am happy to say that these goals have been achieved. In the video, the crawler has no trouble driving on ice and frozen grass, and I also made a course out of books to test the crawler indoors. When driving outside, the temperature was -2C. The crawler is powered by 2 L motors, steering by a servo motor as well as engine and winch controlled by M motors. Video: Pictures: Thank you so much for watching and reading! Looking forward to your comments! BbBT -
[WIP] 4x4 Crawler (More or less done!)
BrickbyBrickTechnic posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hey everyone, This MOC is being built for 2 reasons: 1, to celebrate 3 milestones- Canada's 150th anniversary, Technic's 40th anniversary, and me hitting 1000 subscribers on Youtube. In fact, a comment suggested I do this. The second reason is to cure the errors that my 2 previous crawlers had: -weak axles (very weak in fact) -low climbing power -messy building -inefficient steering (used an M motor) -no additional RC functions So here's where I'm at right now: Above is the motor housing. I'm going with 2 L motors for the drive because they have good speed at a sufficient torque. That is the gear housing. Frames are abundant. Now the whole front axle. You can see that it is compact and yet very, very durable. The rear axle. And the two together. This crawler is being built for max performance but awesome looks. So I want to (but may not) do a Tacoma body: Update tomorrow, thanks for reading! BrickbyBrickTechnic -
Okay.... I am already super-backed up on projects and cannot take on another....but someone absolutely needs to make this machine! in LEGO!

[WIP] 1:50 NASA Crawler Transporter
OzShan posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I am getting close to the end of this long term build and it's time to share some pictures and a bit of the story. Even before I had finished putting together 10231, I decided I wanted a Crawler to go with it. Being a Technic fan it had to at least drive around and lift the launch platform and shuttle. Those two basic goals spawned a project that has lasted a little over 2 years so far. Some ideas have stuck around since their inception, others were a bit optimistic (like building a peristaltic pump and hoping I could find a way to control the pneumatics hydraulically). February this year marked the 50th anniversary of when the two crawlers went into service, so recently there has been extra motivation to finish. The base equipment; - 16x M-motors (drive) - 4x L-motors (pneumatic jacking and leveling) - 4x IR Receivers (V1 as the V2s do not like driving multiple m-motors on a single channel) - 4x NXT servo motors (steering) - 4x RCX rotation sensors (measuring jacking level between truck and chassis) - 2x NXT bricks (one master and one slave. The master communicates with the Android Tablet and coordinates itself with the slave. Programmed in LeJOS) - 1x PF IR-Link sensor (link between master NXT and all PF motors) - 2x PF Battery boxes (with thermal overload removed) - 1x Android Tablet Future add-ons - Accelerometer (automatically detect the crawler is on a gradient and adjust the leveling to suit) Bricksafe folder is here: http://www.bricksafe.com/pages/OzShan/Crawler Firstly, a couple of my favorite reference pictures; The build itself started with the trucks, thinking that the pneumatics and LAs would dictate the scale. First proof of concept - build a coupling to give height, pitch, roll and yaw to the truck. The pneumatics need to be on their own gimbals too. The reinforced 2x2 rounds slide and rotate in the 4x4 macaroni's. It is on the limit of what will hold together without glue, but it does hold. The two 1x2 technic bricks at the base of the 2x2 column are helped a little by a string (not pictured) which runs up through the 2x2 rounds with the axle. Initial prototype of the drivetrain. I would have liked a higher ratio but there was just no room at this scale. When the gearbox was married with the truck chassis I had to juggle positions, so you will see in later pics the crown gears are facing in not out Best laid plans.... Marry studded and studless they said. It will be easy they said... Showing what will eventually be the steering between chassis and truck. The guide tube and pneumatic cylinders are all on gimbals with the pneumatics coupled together. The average height is preserved during any tilting. With prototypes sorted, it's time to bricklink some parts and quieten down the colour scheme! (thank you 42030 for providing 5L thin liftarms with axle hole in LBG color) You can see the relationship between "guide tube" and cylinders here. The pneumatic system was overhauled too many times to remember but this is what it arrived at. It is all controlled by the direction of the motor. Running forwards drives the pump. When running backwards, the lobes operate the pneumatic valves in series, letting small amounts of air escape each rotation. This lowers the chassis in a slow and controlled manner. The motor can be turned on or off and run in either direction at any time due to the valve timing. Early attempts with PF Servo and NXT servo just couldn't park the valve reliably and after a few operations I would hear a slow leak. I have been trying to keep up with the LDD but it's hard to stay motivated when I know I'm just going to have to suck it up and move over to LDraw if I want to include all the motors, pneumatics and LAs Works so far; (I'll make the files available if anybody would like them). I found LDD essential in the early days to plan ahead and simply find parts, but later on the build overtook it. Original 'box' pump. 1x PF XL motor, 4x 6L pumps running at 90 deg to each other. Very smooth but bulky. Flatter attempt in the same vein. The truck itself. The final design for the height control modules. I hope you enjoy the build so far. More pictures to come of chassis, steering, leveling and interior details. I'll leave it to others to decide what 'theme' it belongs to . -

How about that little cross between mud and go on the rocks? Crawler 4x4 always ready for it! Still would! Its wheels are shod with tires RC Rock Crusher X/T 1.9, coupled with portal axles and two motors running by SBrick and LiPo battery box - we have an off-roader with excellent maneuverability, suspension geometry and a low center of gravity due to the unsprung axles. Crawler 4x4 built under the rules of the forthcoming Off-road trial competition in Moscow, at the same time. I tried to build the chassis in such a way as to achieve maximum throughput and maximum flexibility - namely, so this chassis can set the wheels of virtually any size from 62 to 108 mm. The body of the model removable. This allows the chassis to this every body, even though the truck, even an SUV. Get more photos on my blog of flickr

[AMS1] 42056 Porsche 911 GT3 RS Crawler 4x4
Zerobricks posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I decided to open a seperate topic for this beast. Inspired by Letsbuild's idea to crawlify a Lego set, i decided to go full crazy and try to upgrade the biggest, heaviest and most orange set to date, Porsche 911 GT3 RS. First thing I built was the front axle, which uses the H frame as a placeholder for bewel gear, so there it no possible way of them to slip: Those with sharp eyes may notice the gears are not aligned, this was done in LDD development mode, more info soon The drive than goes directly to portal hubs with 1:3 gear ratio, giving the model 1:5 gear ratio on each wheel. Front axle also has a servo motor which steers the wheels and powers the Porsche's original steering wheel via a ball joint Rear axle powers the Porsche's gearbox via a couple of clutch gears in order to allow different motor speeds when steering or skid steering - Yes, this 4 kilogram heavy model can even skid steer thanks to its independent motor control. Here is the end result As with the original set, I kept the rear axle 2 studs wider than the front: For suspension I used 4 hard springs, which are hald compressed thanks to the model's immense weight. Due to the porsche's wide chassis springs are quite far apart, so the flex angle is not really big, but on the other hand that makes the model much more stable. Performance wise the crawler works very good, despite its massive weight, so far I had no broke U joints or gears and it has enough torque to skid its wheels on hard surface. Expect more pictures soon and a video soon. -

[MOD][AMS1] 8258-B Crawler
JTS posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Presenting the 8258-B Crawler, Designed and built as an entry for the 'Crawlify your set' contest [AMS1] I'm a huge fan of b-models in general, but the 8258-B has always been one of my favourites due to great looks and an easy to modify. Or so I thought... In the end, I reckon about 85% of the chassis has been custom built. There are two L motors situated just below the cabin. One powers the front axle, one powers the rear. Both axles have differentials because, being independently powered, loss of traction is a lot less likely and it saves my poor pieces from becoming mangled. Because the 8258-B is rather small (read: narrow) I had a lot of trouble designing a front axle that could house a servo motor without limiting the range of suspension travel. Eventually I gave up and ended up modifying this axle to accommodate a differential (well deserved credit to the amazing @Madoca 1977). However with that said, I have made sure the bodywork stays almost 100% true to the original. The only alteration I had to made was to the rear wheelarches to make room for the balloon tyres: Original wheelarch Modified wheelarch: Also, the front winch kept scraping on obstacles I was trying to climb over so I switched this out for a bullbar, however the two are easily interchangeable. Anyways, here's a video of this thing in action. As always, please let me know what you think. Whether it's praise, criticism or telling me off for building ANOTHER red and black model (I have other colours, I swear!!), I'd love to hear it. More images can be found in this bricksafe folder. Enjoy =) -
Using L-motor to power crawler
Rooneypower posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello all, I have a few questions regarding the use of 2 L-motors for powering a crawler. I have done some research and have not been able to find many MOCs that use L-motors for drive, does anyone have any advice on using them instead of 2 XL motors for drive. I know the torque output will be less with the L-motors but the overall speed will be quicker. If geared properly couldn't a L-motor be able to closely match an XL motor, but spin faster? Netting me more of a buggy type of crawler instead of a pure crawler? Also if I were to use L-motors I can keep the overall size of my axles smaller. One of the downsides is the power draw from the 2 L-motors will be too much for a Lipo battery setup, correct? I'm building some custom axles in LDD and cannot make up my mind which way I should go with my PF, XL drive or L drive motors. I have designs for both size motors, any advice or experience would be welcome, thank you! -

Lego Volvo Af25 suspension 42030 crawler (plus instructions)
The Vooduist posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Wished I posted this sooner......... When I was originally had the model normal it couldn't go over an half inch actual brick tile :(. Due to that I spent a long time modifying it to barely go through grass about as tall as the pretend sticker grill. This thing can go over an emaxx tire with its 2 not one xl motors and it had an l motor for steering (only do if your not using 3rd party tires) if using 3rd party tire use an xl motor for steering (I only had 2). I'm now building a a25E tanker to spray weed killer for me so I don't need to sweat to death. Since its super easy to detach the bed I could be able to switch the tanker and soon changed bed be swappable maybe? Picture from very first successful time. Version 1.0 instructions: http://bricksafe.com/pages/Voodu/42030-dump-truck-super-mod-instructions Video as just a quick demo of some average grass: This is what I'm building while doing Ingmar Spijkhoven 6x6 truck and stay tuned! -
6x6 truck VS
shuoshuoliuliu posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
just made a truck similar with Mr. Madoca's new moc work same function on differencial lock and 2 speed gearbox，but 6x6 -Weight: g -2 XL motors for propulsion，1 XL for 1st axle，1XL for 2nd、3rd axle -2 Servo motor for steering，1st & 3rd axle -M motor for 2 speed gearbox -M motor for locking rear differential，1st axle - 2nd、3rd axle -Portal axles for 1st、3rd axle in order to make a powerful crawler, I need different rotating speed of front and rear axle. For the reliability, I not use the weak center differential. I design 2 seperate XL motors for 1st axle and 2nd+3rd axle. But I add a lock, to lock the 2 XL motors together when necessary. That means there are 2x 2speed gearbox + 1 lock. And to make sure the enough power, I add 2 battery boxs. -
[MOD] FJ40 Crawler with SBrick
Madoca 1977 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello everyone! This time I built a modification of rm8's Toyota Land Cruiser FJ40. FJ40 Crawler Weight: 1145g Propulsion: XL motor for 4 wheel drive Steering: Servo motor 2 speed gearbox: M motor Winch: M motor Headlights: PF light Powered by: SBrick and 8878 rechargeable battery box This is my third SBrick model. One SBrick and a rechargeable battery box fit well in the rear space. Unfortunately tumbler tires from 42050 cannot use for front axle. They touch the connectors when steered. So I used normal balloon tires. One XL motor has enough power to climb the slope of over 35 degrees even in high gear (4.2:1). It can climb much steeper slope in low gear (12.6:1) but less-grippy balloon tires would start slipping. You can see that situation in the second half of the video. Building process was not straightforward. First, I decided to adopt bigger wheels, working headlights, motorized two speed gearbox and winch. Also I was planning to keep the whole original bodywork as possible. Like rm8’s chassis, it has front and rear live axles with 3 links. In offroad driving, 81.6mm wheels require gear reduction after differentials. My first attempt was using central torque vectoring diff and rear portal axle like my Off Road Pickup. Front axle was not changed. Although it kept the same wheelbase as original, this version was failed. Every time I started driving, 20t bevel gear and diff disengaged. Second plan was using front and rear portal axle. I tried to make the wheelbase as short as possible. It became five studs longer than the original. So I needed slightly longer body. Building whole chassis was the most difficult. The problem was how to minimize the mechanism of motorized gearbox. I used new driving ring and red clutch gears. I felt that they were stronger elements than old version and they could handle more torque. Although 2 speed gearbox was simple, I had to hide the whole mechanism under the seats. I eventually squeezed a mini linear actuator into the left of gearbox. Changing gears is not fast, but it's easy to adjust lever in neutral position in case of using winch. The winch mechanism is the same as the original. It is powerful enough to help climbing steep hills. I have to say that rm8 had achieved perfect weight distribution. I recognized it when I was attempting to build various versions of chassis which had different motor locations. So in my final version, all PF elements are in nearly the same position as original. The bodywork needed some minor changes due to the new chassis and my parts assortment. In original “face”, it was impossible to put LEDs into behind the headlights and shine trans-clear parts. Moreover, Round tile 2x2 trans-clear seems not to be the official parts. My alternative was built out of available parts. I know the original looks far better and hard to change. But it was worth for me to find another solution. Original FJ40 is modular building. It has various options like doors, roof and snorkel. Since my MOD became bigger and heavier, I didn't add the roof. (Still, four soft shock absorbers are slightly compressed when it stands stationary.) Instead, I built detachable doors in two versions.

MOC 4x4 Rock Bouncer
sacm93 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
G'day from Australia everyone! This is my first topic created on Eurobricks and my first serious MOC since the end of my "dark age". I'm seriously super glad to be here and keen to share my Technic creations with you all from now onward. With this in mind, if there's any way I can improve how/what I post, by all means let me know so I can keep everyone (including staff) content. I am committed to giving this site the full respect it deserves. :) As a few of you have suggested, it's a good idea when coming out of your dark age to develop designing/building skill by drawing on other people's MOCs for inspiration and guidance for different building techniques... Partially inspired by SevenStuds' recreation of Tim Cameron's rock bouncer "Showtime", I present my own 4x4 Rock Bouncer. Features.. Drive: 2 PF XL motors (1 per axle). Final ratio is 3:1. Steering: 1 PF Servo motor with rack and pinion Suspension/axles: Full-time locked solid live axles with portal hubs (geared 3:1), suspended by 9.5L shock absorber (soft) (2 per axle) and stabilized by a double triangulated four-link setup. Tires: Third party scale RC tires similar to the "Rock Crusher" by RC4WD. Battery: 1 x PF AA battery box Receiver: 1 x PF V2 I initially began designing some kind of rock crawler which was to include PF XL motors, third party tires of some description and (after quite a while researching suspension design) double triangulated four-link suspension. This kind of suspension is ideal as it provides maximum articulation and strength of the axle while eliminating the requirement for a Panhard Bar or Watts Linkage because the triangular positioning of the upper and lower control arms oppose each other, eliminating sway and allowing all desirable movement. By far the most difficult part of designing was the requirement for a steering shaft which moved harmoniously with the suspension cycle of the front axle. Because the upper control arms are shorter than the lower ones, the angle of the axle relative to the chassis changes through it's cycle and this means that when positioning the steering shaft, it must be such that the radius of it's motion doesn't change (due to angle change) as TLG doesn't offer any part which works purposely as a slip joint to negotiate the effect of plunge. After many, many, many... many attempts, a sweet spot was discovered which offered a negligible discrepancy. (This was a happy moment). It's biggest performance drawback would have to be that when the angle of climb and drive torque applied is too great, the rear lower control arms buckle and the rear axle begins to walk under the chassis. Trust me, it's cringe-worthy. With 15L beams instead of 16L links and consequently different suspension geometry, however, this could be resolved. The turning circle also suffers due to the wheel base. Overall, I am reasonably happy with the final product as it is capable of most of the things I intended it to be and in my opinion, the body could look worse. ;) I unfortunately don't have video footage, but I do have photos (see below). Enjoy! All comments welcome. :D -
[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... -

Lego Technic Trial Truck 4x4 (not Tatra)
filsawgood posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi everybody! Today I present to you my first experience of construction Trial Truck! During this year I was looking for your ideal 4x4 chassis. And in the end I came to this building. In the final, which turned this freak on 4 wheels medium size range (80-82 mm). The main idea of this project was the task of the displacement of the center of gravity down and forward is not at the expense of detail, as well as the compulsory use of the portal gears on both axes for high permeability and stability of large CG. The power installation in the form of two twin L motors located in the rear axle, where through the reduction gear torque is distributed to the axle gears back and forth, and then the rotation of spreads on all wheels through a gantry gearboxes. This arrangement limits the transverse rear axle moves up one degree of freedom. Yes, the rear wheels are posted on the obstacles, but discomfort on the track it does not deliver. Servo motor for steering is mounted on the front axle, which also lowers the CG and the sprung mass model. Power - LiPo, management - Sbrick. Number of pieces - 875 pieces Weight - 950 grams More photos you can find on my flickr and blog -

[Previous Post: ] Hi, guys: Name's Mun and I am new to this forum. Thought it would be great to introduce my self and post my very 1st technic creation. The suspension bogie is copied from "Nico 71" and everything else is my very 1st attempt :P Any suggestion or comment will be appreciated. Thanks ! [updates:] Haven't started working on my transmission yet since I am experiencing some delay with my orders. However I do have some updates for you : P I will let the video do the talking. Some thoughts: 1. Will switch to a lighter colour (probably light green) at the end of this project since there're still a lot things need to be changed. 2. Will use this as a platform and build all different kinds of mechanisms on the rear "cargo module".
