    A tiny monster truck, features all wheel drive and steering, torsion bar suspensions, changeable gear reductions and power source, and openable hood, with building instructions. I wanted for a while to build a tiny monster truck with the big wheels of the Lego Xerion with a special color scheme. The first idea was to use lime and blue color from the lego #42037 but I had not enough parts in correct color to have a good result, that is why I changed the idea and try a different approach with a red chassis, white body and some touch of lime, but without neglecting the bodywork. I have chosen to design the chassis in red color, like the iconic lego crawler #9398, using one L-motor on each axle with differential, with a simple but effective drive train. The use of portal hub enables the easy change of the gear reduction, to have a maximum torque (8/24t) or maximum speed (16/16t). It was an important thing for me for the drive train to be easy changed. The steering is operated by a servo motor, placed centrally in the chassis, and uses the ball-join frame to passes the axle of the steering. As the servo motor is not directly on the steering axle and uses 16t gearing, I have to use a small trick to avoid miss-alignment of the steering, by shifting some tooth of the 16t gear to have the correct tooth of the 12t gear on the rack. (you can see it on the building instructions). The suspensions are based on the same design like my Mongo Truck, the CVT truck, or orange trial crawler since lego have released the ball-join hub with frame. Therefore the axle are composed of a ball-join hub frame, with two links on the side but the shock absorbers are not made by using springs, but torsion bar. A link connects the axle with a lever, which is mounted on an axle which can not rotate. The suspensions are therefore create by the torsion of the axle. It enables to have adjustable soft suspension (by moving the fixed position of the axle) and more compact than a spring for vehicle in small scale. But this suspension can not handle a drop of the vehicle without end stop to prevent breaking the axle. Regarding the design of the bodywork, as I mentioned, I wanted to create a tiny truck with good mechanical and simple design but also a nice bodywork. I have chosen the white color for the bodywork which fits nicely with the red chassis, and some touch of green using the lime soft axle, but you can of course consider every color you want as the design is pretty simple in the parts used. I also wanted to put some nice details in it to reinforce the playability, like the possibility to choose the power source. My model uses standard battery box with IR received V2 but a buwizz of a lipo with sbrick can also be installed. The last detail is about the openable hood which reveals the big V10 block (not working sorry) and some others details like a dashboard and exhaust. To finish with the trial truck abilities, there are good, despite the fact there are differentials on each axle and the wheel base is short, but the truck has a low center of gravity, a good torque on wheel (with the 8/24 portal hub), good traction with the tires and the responsive suspension and small turning radius. Of course it can not compete with heavy slower truck with many motors but it is very playable and fun, especially if you choose the buwizz of sbrick solution to avoid the IR detection problem under the sun. To sum up, this is a fun and powerful tiny monster truck, which can be modified by the user (changing power supply, gear ratio, color scheme), that is why I have created a free building instructions based on reverse photo sequence !

    Hello, I present you my new creation ! A motorized rally car transformer which transforms from a car to a robot. With building instructions. Context I must admit that I am not a huge fan of Transformers movie and robot fight, but I like mechanism and wanted for a while to build a real car which can transform into a transformer robot with not only the chest and head to move like a toy but all the body, including the feet, legs, chest, head, arms and so on. Then, I decide some months ago to start this creation by seeing the work of barebos on youtube who have made a prototype. I have made many prototypes to have the correct dimensions and proportions for the robot and then design (or trying to design) the car. Here is the final result. Functionality This model has only one function, which is the purpose to what it has been designed (of course you can play with it but there is no steering). This function is the most important and takes the whole space in the model. It is basically composed of : A M-motor which drives the whole system (in red and yellow) Articulated feet lever which deploy the feet under the bodywork (in blue) A double linkage lever to maintain the chest of the transformer to be parallel to the feet lever (in pink) A third linkage which connects the double linkage to the front, in order to reveal the head (in green) The two arms attached to the chest which are moved by a last system of linkage (non represented here) The M-motor drives two system of worm gear. The first drive train powers the pink linkage. This linkage is attached to the blue feet lever which is powered by the second worm gear thanks to the T shaped parts. This configuration with the two worm gears and the double linkage enables to have the chest (basically in red on the picture) to be parallel to the blue feet levers. Thanks to that, the feet can be folded in the chassis like a accordion and takes the maximum available space to gives a nice proportioned robot which raises from the ground. The blue feet levers are necessary to lift the whole transformer by pushing on the ground and to be a part of the feet at the end to avoid falling, the feet touch consequently the ground as soon as the lever start to rotate. Then, the double linkage is connected to the front of bodywork, and the length between pivot point allow a 90° rotation of the front bumper when the whole linkage made a 180° rotation. Like that the transformer can raise from the ground and reveal the head of the transformer by rotating the front bodywork. you can see in fact that the head is hidden inside the front bodywork but is attached to the chest. To finish the arms of the transformer are attached to the chest and are composed of a double linkage system, which makes rotate and move on the side each arm. Each arm is connected to the first double linkage (in pink on the picture) with 6L link. Therefore the doors of the car is the arm of the transformer and the hands are hidden at the back. Design At the beginning I wanted to have the battery box in the model, but I had to remove it because of the weight and that I have not enough place to put a big motor. Even with a big creation to have enough space to put two big motors, the weight was too important to lift the transformer (do not forget that this is the feet which lift the transformer). Therefore I decided to choose small scale to have a small weight and tiny motor, of course the battery box would not be in the creation but apart and connected with a wire. - The main consequence of this was the design of the bodywork. When I have finished the mechanism of the transformer, I was able to start the bodywork, but due to the scale, I could only make a design which was a compact rally car. It could not have a trunk (or maybe with a more complex linkage), and the wheel base was small regarding the scale, because I focused myself to have a correct proportioned robot regarding the feet, legs, chest and arms. Regarding the doors, they are also the arms with the hands, therefore, the hands in black are hidden at the back which is simple and handy, which would be not the case if I chose a different design. This is the same reason why there is a gap between the rear light and the roof, because when the transformer is raising, I have to have enough space to handle the displacement of the roof. The head is also hidden in the hood, which affects the design of the head. I was limited in width but think that I found an interesting combination with black connector to create the mouth and face, plus some white parts, especially the cheese slope which makes the nose. To conclude, this type creation was the first I did, having a car which can transform into a robot. It was very interesting to works to the mechanism especially the complex system of linkage, worm screw, lever, moving and non-moving parts which makes a good working creation. The building is very compact to keep a small scale in order the robot can be raised by a motor, therefore there is not many space to create detailed interior, fake engine, steering, or drive train. The design was also a consequence of that which is not bad (rather cool I think), but maybe a lack of crazy color and shape which can be seen on original Transformers movie. As I said, I not very good in designing manga things. Pictures and Video Go to http://www.nico71.fr/transformer-rally-car/ to see more pictures. Building Instructions At the beginning of this moc, I wanted to make a building instructions because when I searched this type of creation, I did not find with instructions. I tried to make it with photo sequence but it was a total mess. Therefore I decided to create a pro-rendering instructions for sale, at 7.5€, which enables you to rebuilt it, step by step, part by part. Here is the complete bill of material in picture file : File 1 - file 2 But you can also checked it on rebrickable : Want to know if you can build the Rally Car Transformer ? The Rally Car Transformer has been indexed to rebrickable, check it ! To get the building instructions : you can either buy it on rebrickable or on my blog : http://www.nico71.fr/transformer-rally-car/ You can see sample of the instructions : I plan to put in on mochub depending of the price so stay tuned. Fell free to comment :)

    Sorry, I have not picture of leftover parts, and I do not think the suitable of the 42030 bucket is good becausde I design the movement of the fork to be used with a fork (speed and amplitude). And I think the bucket will be too heavy to work with, because of the placement of the linear actuators points (due to the scale). So maybe it is possible but with some modifications and surely a loss in amplitude of motion :)

    Hello, yes the 42030 was an inpiration but as you notice this is completely different by the scale, the functions, the way it is build, of course it looks like a whele loader but the two model is good and has their own reason to be. I like too the red color of the building equipment, the inspiration comes from the brand Doosan here :)

    I am glad that you like ! yes, as I wanted to create a model which was playable and fun to build, I focus on the building instructions, thanks to Kevin Williams, there is a pro one for sale, and there is also a free one based on photo sequence. I also focused myself on rigidity of the structure to be play in hard way, that is why the panel is part of the rigidity. The 8459 was an inspiration for the playbility and the shape of the cab which enables to made the cab as close as possible to the front.

    A alternate model of the Lego #42082, features central articulation with steering wheel, 4×4 drivetrain with fake engine, rear pendular suspension, motorized raising and tilting fork, adjustable fork width and many opening elements. Context Some time ago, I had the opportunity to get the #42082 rough terrain crane before the official release date, then I build the model A for making a quick review and wanted to build also the model B. But I was not happy to see that the model B had the same chassis than the model A but with different turret. That is why I have decided to create a new proper model C which was different than the first building of lego. Therefore I took apart my model A and start designing a model C. Note : I truly understand the lego designer choice about not making the model B many different than the model A. I do not think this is because there are lazy or having not enough time to create a new model B. but because the model A is a big model, with almost 4000 parts, and need many time to build (around 10-15h). As the model is focused for children and teenagers, it was not very good to have to dismantle all the model A to create an other, also because the majority of people who buy big lego set, build the A model and display it for collection. That is why I think, lego designer made this model B as a option of the model A with using the main chassis. My model C is a completely different approach, building for giving to the lego fan one more model to build with a restricted inventory which is easy to get. Functionality The ideas behind the functionality was easy : I wanted to have the cool functions non motorized, and the boring one motorized. It means that the drives and steering are manual, and that the raising and tilting are powered. For me it is the best approach to have the maximum of playability and are the leitmotiv of my creations. The first function is the steering, which is operated by the beacon on the top on the roof and drives the external gearing of the turntable which is fixed on the main articulation. Then the movement of rotation is transferred to the steering wheel by using gear. Like that, the steering is very smooth and realistic with the steering wheel. The second function (which is a passive function) is the drives with the detailed fake engine. The wheel loader have a 4×4 transmission with a fake V6 engine placed at the rear. It uses classically differentials on each axle but no differential on the center because the pivot point is placed at equal distance of each axle. The next function is the oscillating rear axle. It has a pendular suspension with articulation made by a friction-less pin on one side, and the drive-train axle on other side. In order to prevent easy oscillating, I placed a rubber band on each side which tends to reduce the oscillating. There are also two end-stop in order that the tyre do not touch the mudguard at full oscillating. Next functions are the most important, the operating fork with raising, tilting and adjustable width. Only the two first ones are motorized. Indeed, the L motor is placed in the bottom of the loader, on the top of the fake engine. It drives a dual gearbox with a switch on each, like that the functions can be operated independently (and in the same time). The gearbox is on the same principle has the model A, with a central reverser which makes rotate the 16tooth gear with clutch in different way, ensuring the control in both direction of the functions. After the gearbox, the movement of the axle are centered to the chassis, and goes to 2 universal joins underneath the turntable. Then they arrives in the front chassis and powered the large linear actuators below which raise the fork, and the small linear actuator on the top which tilts the fork. The tilting of the fork is also equipped with a special geometry which enable to fork to stay in same orientation when it is raised, similar at the real wheel loader. Regarding the adjustable width of the fork, this is a function which for me as to be motorized for better playability, but it was too complex, that is why this is manual operated. Each fork can slide and they are connected to a rack, then a center pinion make the fork move on opposite direction. – Design The design is a important part, first of all to make the model recognizable and be nice to see for the audience, but also to make the model playable. For me, the design has a visual function, but also have to enhance the functionality or the playability of the model. For example : the mudguard can be opened with a dual link motion and reveal the fake engine and the rear railing cover can be opened. These are panel for only make the design of the rear body, so it has to be nice and well done, but it is also used as a demonstration function. I have also work a lot on the rear paneling of the battery box to make part of the design and functionality to include in this design the two functions : battery box removable, and the easy on/off. The rear bumper weight is composed of many panel with light, and can be rotated to reveal the battery box, it is attached with a 3/4 pin which gives enough friction to lock in position but release it when you pull it out. The on/off functions is made by moving the rear attachment fixed on the bumper weight, it has a small linkage system which pushes and pulls the on/off button of the battery box, and do not lock in position when the bumper is open. you can see this linkage in the video. To finish, regarding the design, I have tried as usual to make the more interesting design with details, nice finishing and homogeneity of the colors and shape. That is why there are mudguard front and rear, access lader, front rear and side lights, angular shape of the glass of the cabin (inspired by the iconic 8459), detailed dashboard, exhaust, seat and mirror. Of course the model do not use all the part of the model A but is quite big, with many detailed and playable. Note that I have created a last section in the video which show some tips and trick I used for this model, like the exhaust, front roof, suspensions, or one/off linkage and I have tried a new photo setup (shooting with a new lens, in manual and in RAW) and enhancement software which gives a better result. I hope you like it. Video and picture Building Instructions The main idea of this project was to propose to enhance the building experience for the Lego rough crane 42082 by creating a unique model C, in order that people can build it by only purchasing a 42082. Therefore there are two building instructions. One for sale at 10€ with pro looking (like the official lego one) made by Kevin Williams, and one for free based on detail photo sequence. Therefore, you can buy it to support me, or just watch it for free, as you want. Here is the complete bill of material in picture file : But you can also checked it on rebrickable (if you do not have the 42082) : Want to know if you can build the Wheel loader 42082 Model C ? The Wheel loader 42082 Model C has been indexed to rebrickable, check it !

    Build The Impossible

    Hello, first of all many thank for your words, we are happy that you like it. To answer to some questions, the idea was to build an contraption machine using 25 cranes. All modules/ movement are driven either by gravity or motor, and all module starts an other module step by step. There is not remote control. So yes we have made many try to obtain a cool layout and nice finish with the trebuchet. The 650h is the total hours to build, assemble, test, rebuild, set up and so on. Each crane take 12hours to build, + modifications (like motorised function, triggers and so on). Some other module take more time to create. But I think we take 80% to build and 20% to set up. Regarding the video, lego technic has published a one shot video on youtube, with some speed up in it, and other video which show a bit more about the module and trigger : https://www.facebook.com/LEGOTechnic/ I plan to make some video about the building and how it works, especially my module. But feel free to ask for questions :)
