I already planned to open this topic back in March or April, but I got caught up in work and stuff. Recent discussions in the 42129 thread makes me feel that inow is the good time to start it. My vision for this thread is that it will be a directory that contains the PF conversion mods for all of the Control+ sets so far. I have created a few mods myself as well. And I'll try to keep the information organized by updating this first post. If you have any mods, feel free to contribute. This thread can also be the directory for Studio models for the C+ sets, so that anyone with a mod idea can give it a try. ------------------------------------------------------------------------------------------------------------------------------------------- 42099 Available PF mods on Rebrickable: https://rebrickable.com/mocs/MOC-28766/olivierz/4x4-x-treme-off-roader-42099-power-functions-base/#details ------------------------------------------------------------------------------------------------------------------------------------------- 42100 There is currently no PF conversion mod available on Rebrickable. I've designed two PF mods for this set in Studio, but I haven't published yet because I haven't made the mod instruction. They will be published later this year. The mods are: - Full RC PF conversion: This mod replaces two hubs with two PF battery boxes, replaces all motors with 7 L motors, and adds 4 RC receivers. - Motorized PF conversion: Because a big empty box with 7 motors engaged in direct transmission is boring, I want to add something more Technic-ish, more mechanically interesting. This mod removes all hubs and motors for the base, which makes slewing and driving manual, and add 1 PF battery box, 1 L-motor, and a gearbox with 4 multi-directional switches for the functions of the super structure. Thanks efferman for sharing the base 42100 Studio file. ------------------------------------------------------------------------------------------------------------------------------------------- 42109 My free mods: - L-motor steer: https://rebrickable.com/mocs/MOC-84883/nguyengiangoc/42109-pf-conversion-l-motor-steer/ - Servo-motor steer: https://rebrickable.com/mocs/MOC-84884/nguyengiangoc/42109-pf-conversion-servo-motor-steer/ ------------------------------------------------------------------------------------------------------------------------------------------- 42114 My free mod: https://rebrickable.com/mocs/MOC-85933/nguyengiangoc/42114-pf-conversion-servo-motor-steer/ ------------------------------------------------------------------------------------------------------------------------------------------- 42124 My free mods: - L-motor steer: https://rebrickable.com/mocs/MOC-84954/nguyengiangoc/42124-pf-conversion-l-motor-steer/ - Servo-motor steer: https://rebrickable.com/mocs/MOC-84955/nguyengiangoc/42124-pf-conversion-servo-motor-steer/ ------------------------------------------------------------------------------------------------------------------------------------------- 42129 My free mods: - L-motor steer: https://rebrickable.com/mocs/MOC-84984/nguyengiangoc/42129-pf-conversion-l-motor-steer/ - Servo-motor steer: https://rebrickable.com/mocs/MOC-85004/nguyengiangoc/42129-pf-conversion-servo-motor-steer/#details ------------------------------------------------------------------------------------------------------------------------------------------- 42131 My free mod: https://rebrickable.com/mocs/MOC-92919/nguyengiangoc/42131-pf-conversion/ ------------------------------------------------------------------------------------------------------------------------------------------- 42160 My free mod: https://rebrickable.com/mocs/MOC-161275/nguyengiangoc/42160-pf-conversion

Dear all. Allow me to introduce my latest MOC which was in development long time now, its supposed to be scaled replica of CLAAS Torion 1914 wheel loader from CLAAS company in 1:17 Scale. The reason why i chose this moc was due to lack of other "colour" machinery in this segment and also being kind of specific wheeloader for agrocultural sphere which i love. Claas Torion 1914 is colaboration with Liebherr on joint wheelloader project, Liebherr version is L550 and up. Model is combination of technic chassis and functions with system easthetics. Over 2000 pieces and 4 motors of Control + type allows for good looks and good playability, althrought a bit limited by weaker PU motors compare to PF, i chose PU to get in new wave of tech + easier and cheaper accesibility on market as the PF functions are getting more expensive. Functions are provided by 3x L PU motor and 1x XL PU motor Driver 1x XL Steering 1x L Pneumatics #1 1x L Pneumatics #2 1x L Each L motor serves for pump and switch together by sariel pump/switch combo, but modified to suit my needs in this build. there are two 6L pumps connected to each motor without any air tank so the actions are not so snappy and responsive and it all depends on the power of motors and batteries. due to this i am seriosly considering upgrading to Buwizz 3.0 to see if it will make it perform better and faster. I don't usually know what more to type about the MOC so i will answer every question in comments section if i will be able. Enjoy the photos (video later today)

I started playing around with the idea of European style semi truck again. I built a prototype to test the chassis design with motors side by side. The core idea here is that both motors are oriented towards back so you can put the medium Technic frame on top of them as well as have cables managed up front. EDIT: final version of the semi: Instructions: https://rebrickable.com/mocs/MOC-90482 (RC Semi Tractor) https://rebrickable.com/mocs/MOC-90484 (Box Trailer) Update: https://rebrickable.com/mocs/MOC-152433 (Manual Semi Tractor) The first iteration/prototype: Prototype showcase: It'll take some time before I'll finish the whole semi truck build, but I prepared the instructions for the chassis so you can build it. Instructions are available for free on Rebrickable: https://rebrickable.com/mocs/MOC-86118 Sneak peek of the instructions:

Hi This weekend I could finsish the 8x4 dump truck project which I started somewhen in February. It is a simple 8x4 dump truck inspired by Scania G450XT. The functions are driving, steering, dumping and automatic tail gate locking. Everthing is controlled via Powered Up. I control the model with the brickcontroller2 app. For propulsion I used 2 x PU L motors and for steering and dumping one PU L Motor. I'm really happy with the PU system. For this moc it works great and the model is powerful. At the front axle I developed a new supension system. it is inspired by leave spring systems. However, there are no leave springs since I haven't found a proper solution for LEGO. Anyhow, the suspension works great. The model is built in scale 1:16.5 and fits to my telehandler and other mocs and Technic sets (42043)

Hi, after some time I am back with new project worth sharing even in WIP state. After building my 8x8 Tatra (that was used for truck trial competition), I started building smaller scale version of it's chassis. It went good, but then I got stuck for approximately half a year with front and rear axles without central section on motor selection and bilding steam airship (see pirate forum for more details) . The chassis was laying under other projects and I slowly started daydreaming about building new and better firetruck. Well, first red brick was placed on the finisged chassis on the end of November 2023. Then during the xmas holiday I built the cab, and then foind out I do not know where to aim this project. I was thinking about firetruck with some kind of bucket arm or crane, or some heavy duty tow truck, but the idea of firetruck with working water gun was still there. So I have scratched sketchy outriggers that needed 3d printed wormgear (other thread direction than the original) and started building basically the airport crash tender without the typical roundy cabin... Well, enough stories. The MOC needs 3 C+ HUBs so far to power all functiobs, 6x6 drive with central diff lock, fully articated front and top watergun arm, and function switch gearbox. I plan to build it with full lights and pybricks control. Even it has more than 2kg so far, it is still a decent offroader. For a wjile was I considering building it all neon yellow, but then I checked the parts availability. Maybe next time. :D More info will come soon. More photos: https://bricksafe.com/pages/horcikdesigns/tatra-chassis-with-rc-firetruck Updates will first appear on my IG profile (horcikdesigns). Front mask with cabin: Mechanical controls of the front water gun (rotation and elevation) With 3d printed custom 7x3(4) frame the worm gear can go through and help rise the arm. Probably will try to use linear actuators in next iteration, as this adds too much friction and stress to bricks. Do you have some ideas how to achieve it? So, what do you think? Does it make sense? :D

Control+ Technic MOCs
bruh posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hey everyone! I started this topic because I have (and use) control+ in my MOCS. However, there isn't a dedicated thread on Eurobricks for control+ MOCS. Hence this exists. Firstly, what hub is most commonly used? I have 22127, but I also use the Spike Prime Hub 88012 to control my models. I prefer 88012 because it is smaller and more compact and it also uses different coding: either Python or Scratch. Which is easier to use for everyone else?- 2 replies

Good day, everyone! Each winter I hope to build some offroader to drive in snow, and each winter something goes off. Finally in 2022 I,ve finally built what I wanted - big orange snowmobile with control+ electrics and sprockets from Liebherr/ SNOWMOBILE "TRIDENT" Two main parts are the chassis and the body. Let's start with former. Front side - as it is snowmobile it is fitted with two steerable skis. Suspension consists of parallel levers with two big yellow shock absobers and two hard small shock absorbers between the levers. Suspension is strong enough to bear the weigh of control+ smart hub with 6 battries, body parts and optionally Darth Vader as the driver. Skis are 5M wide and each one has two small rubber wheels inside to add traction on smooth surfaces (with them you can steer even on smooth floor - without only on snow) front suspension has positive castor angle. Which looks cool, but required some tricky techniques to implement steering - for example - for steering I used Large Angular Motor (or simply LAM) it is in parallel with suspension levers, but connected to chassis and smarthub with angle. Next - rear part - all driving motors (2 XL) are inside the tracks. Reduction gear is 28:36 (or 1:1,29) - keeping motors inside the tracks reduces the weigh of body which is good for suspension travel. Long shock absorbers work for vertical movement of only rear part of vehicle, whereas short sh.a. are used for vertical movemnet of whole body (long sh.a. act as parallel levers) And finally - the bodywork. I think this is for now the best bodywork I've ever made for MOC - it is orange, it looks good and its reliable and rigid enough so you can grab this Snowmobile by most of it's orange sections and nothing will fall away. Furthermore, all panel are locked in places and don't wiggle at all. I've even used aquaman's trident from brickhead as mascot when I figured out that Snowmobile looks a lot like trident from above. For everything else that you need to know i invite you to watch the video: P.S. I wanted this snowmobile to look loke a fish. But it turned out to be closer to shrimp or prawn :)

Hi Everyone, Here I describe a method for measuring the efficiency of a gearbox using the Lego Technic Powered Up hub (Control+) and a motor to lift a weight. Gearbox efficiency is defined as the ratio of the output power to the input power and here I show how to measure each of these values to allow you to calculate the overall efficiency. Gearbox losses are due to friction within gears and axles rubbing on the liftarms. By measuring these losses gearbox designs can be tested and improved. Efficiency values are calculated and shown for several gearing combinations and for an automatic gearbox design.

From promobricks.de: This vehicle could best be described as a driver's seat with two huge chains on the left and right. Red rubber studs are attached to the black chains, which are apparently new. The transformation vehicle is generally in white and black with red accents. You can control the vehicle via Control +, as the name suggests, it can also be transformed in a certain way. The set consists of 772 parts and costs 129.99 euros. Set number: 42140 Name: App-controlled transformation vehicle Number of parts: 772 Release date: March 01, 2022 RRP: 129.99 euros

Good day, everyone! This project has started as an idea of creating better a bodywork for 42099, but after some time in development it turned into undependent rc modification of Defender 42110. I took inspiration from Bowler WildCat and Bowler Nemesis which are extreme buggy-like offroaders based on Land Rover cars. So I pondered the question, What if... new Defender would be made into Bowler? In result - original defender has become lower, has got lower roof profile, bigger tires, front and rear pushbars, snorkel pipe, stronger footrests, two sets of additional lights and fog lights, antennas, front and rear mudguards, some chains ('cause chains are cool!). Engine was swapped from 6-inline to V8-supercharged! (After I made this model in spring, LR has announced that they will actually make a V8 Defender. Sadly, not supercharged :) Engine and cooling fan are connected to the front axle via chain links. (Yes, chains ARE cool. I had to buy whole Ducati set for this) And the most important - Control+ components. As this Bow-fender shares control profile with 42099, set of electrics is the same. One XL+ for each axle One L+ for steering SmartHub for SmartThings And then I found out that I am... well... not really good in making offroad chassis. At least it was my first try. So I tuned it as much as possible and made a note for future to learn more about lego offroading. (I think, I'll start with Zetros). Video of how this Bow-fender drives on everything it can is of course here: Watch till the very end! And Thanks for watching. Subscribe. P.S. This cat was walking nearby, while I was making video, so I asked him to participate. So there is A cat in the video now, instead of THE Cat - erpillar :)

100% made out from parts of set 42114 - Volvo Articulated Hauler 100% controllable with official Control+ App This replica of Volvo N10 Truck is an alternate build (B-model) of the set 42114. This means if you own the Volvo Articulated Hauler, you can completely build this alternate model. Other parts from other sets or spare parts are not required. This model of Volvo N10 Truck is a massive biest. It is more than 58 cm long, 20 cm width and 21 cm height. With open bonnet, the model reaches a total length of 65 cm. This alternate model uses 2041 parts, which are more than 93% from the parts of set 42114 Volvo Articulated Hauler. Follow this link for more pictures and content. Visit rebrickable for building instructions. Impressions Doors of the cabin can be opened to access the detailed interior. The bonnet of the Truck is 90 degrees openable to reveal the V6-engine that is linked to the drivetrain. The model uses the gearbox and housing from the Volvo Articulated Hauler. After building step 85 of the Hauler, the instructions takes over to build the Volvo N10. Keep in mind if you disassemble the Hauler, you can leave the built from step 1 to step 85. use of 42114 sticker The alternate model is designed to use stickers from the main model for better look - especially for the front grill. Parts with stickers that show A60H were not used, but the model uses the 3x11 panels with A60H stickers that can be hidden inside the tipper bed. Those four parts with stickers are not required: Battery and Hub access Thanks to the gap between the cabin and the tipper bed, batteries of the hub are easily removable. This requires no disassembling of parts and is done very handy and quickly. The hub is accessable through the cabin, connecting the hub to the App is an easy task. Controllable with C+ App The model is designed for use with official Control+ App and the profile that controls the 42114 Volvo Articulated Hauler. If you are familar with the App and the Volvo, nothing is new here for you, but the alternate model needs a re-calibrating in the settings for steering. If you are new to Control+, you have to download this official App to control the Volvo N10 Truck. With each App interface, the model is completely controllable. Using a third party App to control is also possible. Instructions The instructions for this model are 325 pages long with high quality premium images and different camera angles and views for a satisfying building experience. The instructions will guide you how to connect wires properly and can be found on rebrickable. Here are four example pages of the instructions: The real Volvo N10 To replicate the caracteristic bonnet, cabin, front and headlights was a big challenge. More than 400 parts of the model are placed inside the bonnet. Here are some example pictures of the real Volvo N10 that matches the model most: What makes this model different from 42114? Honestly this model fullfilles with driving, steering, transmission gearbox and tipping the same tasks as the main model with the same App. The Volvo N10 alternate model is a nice looking truck in another scale and again its a Volvo with use of the same stickers. The licensed alternate model is something that you can expect at the back of the box of 42114. Have fun with this alternate build.

Hello everybody, To control my models with the new control+ motors I used the Buwizz app. Now that Buwizz app doesn't support the control+ system anymore, which app is the best to use now?

Hello everyone, I want to share a new creation. This time it is an alternate build (B-model) for the Liebherr LR 13000 Crawler Crane set #42146. You can find instructions here to build the model by yourself. 100% made out from parts of donor set 42146 with no additional parts needed. 100% controllable with official Control+ Application. In order to all functions of that Liebherr HS 8300 Dragline Excavator, you get a complete overview in the following article on how to build, control and calibrate this alternate model. Summary of Functions & Features remote controlled tracks and 360° superstructure rotation remote controlled boom remote controlled independently hoist-rope and drag-rope controllable with official Control+ App for Smart Device using 6 motors and 2 hubs spinning radiator fans detailed cabin playful details like fire extinguisher, ladder, railings and exhaust pipes brick-built bucket 133 cm / 52 inch long 100 cm / 39 inch high high-quality premium PDF instructions includes guide how to calibrate the model Impressions Main control The Liebherr HS 8300 Dragline Excavator is designed to work 100% with official Control+ Application using the already known interface from its main set. Driving tracks and rotating the superstructure works exactly like the LR 13000 does with the original designed buttons on the app interface. Boom control The giant boom of this alternate model is controlled with the right app lever. It drives the longest rope (shown in blue) through pulley mechanism to raise and lower the boom. The highest and lowest position of the boom depends on the limitations of the app after proper calibration of the model. The boom stops automatically in the lowest position to always ensure a 360° rotation of the superstructure without colliding with the tracks. A linkage mechanism slightly moves the nose who is helding the drag-rope and ensures that the app can detect the highest boom position during calibration. As a nice addition, a spinning radiator fan is connected to the same motor that drives the rope for boom. The second fan spins freely. Hoist-Rope & Drag-Rope Controlling the bucket works like the real machine with an independently hoist-rope (shown in green) and drag-rope (shown in red). The hoist-rope is controlled either up or down with the left joysticks vertical movement. By horizontal movement with the same stick, the drag-rope goes in and out. Since this two ropes are controlled by just one joystick, combinations with both ropes are possible and also needed for proper playing. This requires a bit practice though, but makes it possible to control the bucket and two ropes together with just one (steady) finger. The length of the hoist-rope depends on the app limitations for that joystick movement, meaning that the hoist-rope can't go too long before the app stops the motor. On the highest position of the boom, the bucket can reach the ground with fully extended hoist-rope where boom and hoist-rope are in limited positions controlled by the app. During calibration the app also detects the most inner position of the drag-rope. Working under ground With lowered boom and extended hoist-rope, it is actually possible to dig something below the model. This makes fun by placing the model on a table for example. Calibration For a correct calibration by the Control+ app, it is required to separate the hoist-rope from the drag-rope. In the instructions there is a full guide included how to calibrate the model during building. Additionally there is an extra PDF guide included that explains how to calibrate the model at any time. Please make sure you have completed the calibration to ensure the best playing experience with this model. How to build Building the Dragline Excavator starts with the base from the LR 13000 main set. Make sure you build the undercarriage with book 1 until step 343 is completed. Before you continue building, check the tracks und turntable function. After the correct calibration with Control+ app, the instructions for the HS 8300 takes over to complete the alternate model. The premium instructions for this model comes with 338 pages of high-quality images and building steps to ensure a satisfying and slightly challenging building experience for a 18+ set. Make sure to test all functions and alignments of ropes through the building process. Happy people with sealed parts can open bags 3 to 5 to complete the build. Connecting ropes with spools and making nodes can be an annoying thing even for the main model. If you already have built the LR 13000 main set, you can let the spools with ropes connected. The alternate model starts with wound up spools during the building process. Controlling quick guide To become a real Dragline expert under the sun, here are some quick tips for controlling the model: 1) Place the model from the left to the right At the beginning, place your model driving from the left to the right to match the joystick interface for the Control+ app. 2) Sliding bucket over ground This is some basic control for Dragline Excavators. Slide the bucket over smooth surface by controlling the drag-rope winding inside simultanously with the hoist-rope slightly going down. 3) Moving bucket along the boom As advanced controlling, this requires a bit practice but also avoids loosing cargo when the bucket moves along the boom. The drag-rope should go out simultanously with the hoist-rope going up with a bit tension on both ropes. 4) Unload the bucket On a loose drag-rope, the bucket always hangs in the air on the hoist-rope. Simply give some length on the drag-rope to tilt and unload the bucket. 5) Keep watching the drag-rope The app itself cannot detect outer limitation for the drag-rope. In case the drag-rope goes out too far, it is possible that the rope slips over the spool. Treat the drag-rope always with a bit tension. 6) Avoid tension on same direction This case is also not detectable by the app. When the drag-rope goes in simultanously with the hoist-rope going up, there is too much tension at any point. As a result, the parts holding the bucket are going apart at the weakest pin connection. Giving some length on both ropes and connecting them together solves this. Final note Goal with this alternate model was to create something else from the hard discussed Liebherr LR 13000 Crawler Crane. Rebuild, re-calibrate and having fun is exactly the way how this model works. The app goes hand in hand with the design with a large learning curve on controlling the model. Let's find it out by yourself. Think out of the 42146 box and have fun with this replica of Liebherr HS 8300 Dragline Excavator. If you like the design and you even own the 42146 LR 13000, go for it on rebrickable and build your own.

Good day/night/whatever everyone! I want to share with you a little experiment of mine that got a bit out of control. I hope, you remember set 8284 and its really unique looking b-model. At least I do. Furthermore, it is one of my favourite b-models and I really wanted to pay tribute to it. Obviuos thought was, of course, to make it RC with the new Control+ elements. After half an hour I got something that could drive and steer. I even tested it in the local park, but... something was off. It just wasn't enough. However good looking this buggy is, its transmission wasn't created with electromotors and speedy driving in mind. Wheels tended to fall off. Gears in diff broke at least once. And offroading capabilities were...em... on the small side of expectations. And I got an idea! I decided not just to motorize this buggy, but completely redesign, reimagine it from technical point of view, keeping exterior close enough to what it was before. You know, like these like-oldtimer-outside-but-modern-inside tribute cars which car companies sometimes make. Also I wanted to make transformation function more interesting and useful. So, I started on the blueprints... And here it is! All modern all new Dune Buggy! With familiar face which got a facelift. Literally. New version of transformation not just shortens the car, but lifts all front section up While cockpit raises up, special levers make sure that headlights between wheels always stay horizontal. And not only that. Another special lever in the rear section locks the differential using new orange shifter. This way buggy becomes most offroad. And now - to the video! (With the new intro btw)

So many of us, myself included, find powered up/control+ to be problematic to say the least. Every great musical artist or band has a bad song or two in their set list, and control+/powered up is TLGs bad song! It pushes up the price of sets, which might be tolerable if it wasn't for it's downsides, namely no physical remote and it's reliance on apps and third party smart devices which removes all confidence in it's longevity. MOCability is also pretty poor, and set costs can be inflated due to components such as driver chips, tilt sensors and encoders being included in the hub and motors but not actually used by the model. However, it does have some advantages over previous systems, such as it's ability to do more complex things, being able to use motors as motors or as servos, being able to flip the controls when the transforming vehicle flips over, the inverse kinematics of the Leibherr excavator and so on. So what if we could design the next generation of electronics, how would we fix all the issues whilst retaining all of it's benefits? Firstly, I think it's best not to even try to retain ALL of it's benefits. Inverse kinematics is a fun novelty but it soon wears off, is set specific and just not worth the previously mentioned issues that comes with it, but I think it's possible to retain most of the other benefits. I would love to hear your ideas, maybe we can come up with the next great thing! To get the ball rolling, my current idea would look like this: EDIT: over the course of this topic I have listened to feedback and my ideas have evolved quite a bit since this first post. On with the topic.....end of edit. Possibly a 4 wire system, 2 for main power, and 2 more for PWM/data, with stackable plugs. It could possibly reuse the PF plugs for backwards compatibility. A large physical PlayStation style remote with lots of buttons, a couple d-pads, a couple of rotary knobs and two large fully proportional twin axis joysticks, each with a two way rocker switch. Bluetooth enabled, you can pair controllers to receivers by turning on each receiver and activating the controller you would like to control that receiver in turn. A basic battery box. Receiver. Has an input from a basic battery box, an output and a push button for pairing. It has a direct, unfused through path for main power but does not do any switching/pwm control of the main power rail as it doesn't contain a motor driver chip. It controls the data signal only. 3 motors. One is a POWAH motor, one is a regular motor and one is a micro servo motor. They contain their own motor driver chips so it can be better paired to the motor it is driving. There is no internal gear reduction or rotation sensing on the regular and power motors. Gear reduction box. Similar to the internal gearing included in the current motors, this is now a separate unit, allowing you to have as little or as much internal gearing as you want. These units can also be used in other places in the model. Rotation sensor/encoder. Convert the regular and power motors into servos by adding one of these. Can also be used as rotation sensors in other parts of the model. Force sensor. You can add more springs (shock absorbers or drive belts) to get the desired spring force (this would be the load sensor of the Liebherr) Speaker. This would come with a bunch of preloaded sounds (petrol and diesel engines at various RPMs, horns, sirens, helicopter sound, train sound etc) as well as a few spare slots in case a model designer wants to add a few set specific sounds (like for a merry-go-round or steam train or whatever). Different signal strengths would play different sounds. Can optionally be plugged into a computers USB port to load in your own sounds but not strictly required. Has a factory reset button to restore the original sounds. "Code" blocks. Instead of an app/smart device, you have physical blocks that are real life physical representations of them. Most of these affect the PWM signal only with through paths for main power. There would only be a couple to start with but more would be added over the years as sets require them. These could included a NO/NC relay switch, various logic gates, math bock (for multiplying/dividing/adding/subtracting of the PWM signal), servo controller, sensor reader block, delay timer with mode and time selector dials, ramp up/down block, etc. Sounds ambitious, but these blocks allow for much more complex control while eliminating the need for an app or a smart device. It is all "programmed" by the way you build and wire it all together. If the current system is "un-Lego like" will how much more like Lego can you can than physically building your "program" out of physical blocks?! I think that's plenty of options and controllability for any Technic set. It might remove some capabilities, you couldn't use inverse kinematics or control a CNC type machine or robot arm, but isn't that what Mindstorms was supposed to be for? Maybe much of the problem stems from unfortunately trying to make Technic into Mindstorms, resulting in control+ and killing off Mindstorms in the process! Sorry for the long read, but it's not an easy thing to get right and what I suggested might not even be feasible! I should have run it past my embedded systems expert buddy first! I would love to hear your thoughts, improvements, criticisms and ideas.

Good day, everyone. Nowadays, when everyone has to stay at home, I want to show you, how you can spend a lot of your free time with interest. As you know, all Lego sets with control+ system have special "achievements" in the app, which you gain for special actions with set. I've made this video as a tutorial, how to get all the achievements that I know about. Thanks for watching, stay at home! Your Cog In The Machine

Update: Here is the latest version of the arm: Studio model available for free on Rebrickable: https://rebrickable.com/mocs/MOC-109607/glaysche/6-axis-robotic-arm-mk-2/#details Original post starting here: This is my first MOC and first time posting on Eurobricks. A few months ago, I got back into Technic by buying the Liebherr set (42100). I decided to design my own 6 degree of freedom robot. In doing research and experiments for this project, I was inspired by this post I found here on Eurobricks: I ended up making a lot of different choices in my model. Here is the big picture: I wanted to optimize for three things: It should work Maximum range of motion -- the wrist axes should be able to turn indefinitely and other axes should have as much range as is possible Built as compact as possible Here's the video with poor production values (and using a simple BuWizz profile to control it): https://www.flickr.com/photos/188456966@N07/49900167801/in/datetaken/ This was quite challenging to optimize it in this way. First of all, in order for the wrist joints to spin, they needed to be axle driven -- pneumatics won't work. In the example of the grabber at the end, I put an axle through the turntable to control the LA for the grabber. When the grabber turntable is spun, however, the grabber will open or close in an undesired way. To counter this, I used a differential and the correct gearing to compensate. Here's a picture of that: This is difficult to see in there. There is a new 2 piece differential (65413 / 65414) inside the turntable. The gears turn the differential at half the speed as the turntable which makes it so the grabber doesn't move when the turntable moves. The control for the turntable and grabber are axles on both sides that go through the next set of turntables seen here: The axle turns the perpendicular axle that goes through the turntable and is driven by another axle in the next stage. The stage has the same problem as the previous one where flexing the wrist will cause the grabber to turn and open or close. This is compensated with an additional two differentials and another set of gears. This one is particularly compact. Here's a picture of that stage: The lage gear there is a 28 tooth double bevel which is needed to get the correct gear ratio to the 28 tooth differentials. Pulling the side off of that, we see: There are three L motors (22169) here to control the grabber and first two degrees of freedom. I particularly like the gearing in the front of this section for the compensating differentials: As noted by Hanso in his series of posts, the end of this arm is actually quite heavy. I would have preferred to send all three functions though the next turntable but I could not find a solution that sturdy or compact enough. This weight caused trouble for the next turntable. To make this work, I used two turntables, one in compression and one in tension. There is a beam that goes through the center of the turntables that takes some of the load here. The next stage is a another stage that I would like to be able to turn forever so I don't want the wires to get twisted. In order to accomplish this, I also put the battery box on a turntable that turns with the rest of the arm. The wires go through this stage and don't get twisted. The humerus (in LBG) is very small (5x5) and it was a bit challenging to get the gears in there. The motors (XL 22172) for those next two axes very neatly attach there. The base has the last two degrees of freedom. The spin axis here uses a mechanism very similar to the Rough Terrain Crain (42082). The final axis uses worm gears to drive the turntables. There's a lot of force on this axis and I experimented with a variety of different gearing. The thing that worked best is displayed above. The center piece is driven and it gets geared down symmetrically to the axles that have the worm gears. Axle support was a bit tricky here: (Still waiting for the remaining black 7x11 frames to clean up the look here.) The 2nd battery box fits pretty nicely here: In conclusion, I think this works pretty well. I haven't explored the software at all yet -- just used BuWizz as a proof of concept. Many of the motors would work much better configured as servos. I wish Lego would release an SDK for Control+ so I could write an app similar to the Liebherr controls. My day job is actually a software developer so it would be pretty fun to build a full featured app to control this.

Hi everyone, Today I want to introduce to you my latest MOC : a Poclain excavator, the HC 300. Poclain is a French company (bought in 2000s by CASE) leader in 60-70s in hydraulics excavators and engines. The HC 300 was the bigger excavator in the world in 1968 ! Specifications : I wanted to control the model with a smartphone so I used Control+/Power up applications. The excavator has also manual features. I used electrical linear actuators instead of pneumatics to enhance playability. The excavator must be able to rise one track from the ground by using the bucket and his motorized arm. Inventory is mainly based on #42082. The main design is based on 8043 set. The drive train is powered by 2 L motors and a dual differential drive : more informations on @Sariel video : https://www.youtube.com/watch?v=f5_OQooBxdY. This kind of transmission allows control by only one joystick one smartphone screen instead of two sliders. Configuration : 6 motors : 5 L motors (https://www.bricklink.com/v2/catalog/catalogitem.page?P=bb0959c01#T=C) and 1 XL motor (https://www.bricklink.com/v2/catalog/catalogitem.page?P=bb0960c01#T=C&C=85) 2 electrical hubs 2 000 parts Features : - Toggling cabin with mechanical locking system - 360° turret rotation : One battery box is placed in drive train and the other one is placed on turret. No cables through the turntable, only a shaft to transmits rotation from drive train to the V12. - Technical compartments : a lot of openable elements very useful to store tools and tracks components. The grid at the back can be opened to reveal V12 engine. - The entire bodywork is removable. It is only set on the turret by gravity. The entire of the excavator is modular in order to make disassembly easier. - V12 engine works when the excavator move. I add a maximum of details to make it more realistic. - The dual differential drive : Each motor drives one kind of motion, straight-line motion or rotation. Get more information here : http://groups.csail.mit.edu/drl/courses ... ldiff.html. You can also combine motions to get curved directions. Tension on tracks is maintained by springs.

Building instructions too ! I hope you liked this creation, I tried to mix up realistic details and common excavator's features. Only displacement is slow because of a total weight of 2kg.

Hey guys, During a chat I was pointed to the Steinwinter Supercargo 2040. I was fascinated by the look and decided to build it. It was designed by the german engineer Manfred Steinwinter. During my research, I found out that he build only one prototype, but planned many more versions. I liked the three-axled version and so started with a rough sketch to get an idea of the proportions: While I was searching for images of that truck, I also contacted the current IP owner and asked for blueprints. Fortunately he liked my project and he send me some. Since then this truck went through many iteration of improvements and design changes. In the end I decided to use Powered Up to control it. This is the current state: These are planned/implemented features and specifications: Current weight: 3kg Length: 86 studs Height: 14 studs Width: 27 studs Power supply: 4x Technic hub Driving: 4x C+ XL motor, each motor is connected to one hub to spread the load (3,528:1, theoretically 0,74 km/h @7,5V @124Ncm) Steering: 1x C+ L motor, two steered axles with Ackerman geometry Compressor: 1x C+ L motor, 4 pumps 3 RC valves: 3x C+ L motor, 3x newest valve one for each the rear axle, front/middle left wheel, front/middle right wheel Angle sensor for suspension on front and middle axle: 2x C+ XL and 2x Boost Medium motors OR 2x C+ XL Angle sensor for rear axle: 1x motor (not implemented yet) Air/pneumatic suspension on all axles controlled by Powered Up double wishbone suspension on fron and middle axle Each front/middle wheel on the left and right side are one unit. That means if the front wheel is pushed up the middle wheel is pushed down. That way the weight is equally distributed on the wheels live rear axle When I decided to use Powered Up I thought about controlling the ride height somehow with Powered Up. To do that I needed something to read the position of the double wish bone arms and the rear axle. Since several motors in the C+/Powered Up eco system can report their position, tried to use them to read the angle of the suspension arm. I successfully implemented that on the front and middle axle. For the rear axle I haven't found a good solution yet, because that axle can move on two axis. While I'm waiting for some additional parts, I'm working on the solution for the rear axle. As for the code, I already made a proof of concept. I created a test setup and wrote some code, which reads the angle of a suspension arm and adjusts it to the desired value. for the finished MOC a can think of something like a parking height, highway ride height and more or less off-road height. Once the chassis is finished the and the Powered Up is working I'll start working on body. Feel free to leave comments, critique and suggestions.

Hi everyone, I'm searching for the best motor to measure angles. Since I don't have all motors, I'm depended on those, who have them and could a comparison. Requirements: The motor must be compatible with the C+ Technic Hub, used for example in the 42100 The resistance, when turning the motor manually, has to be as low as possible When the motor is turned manually and you stop turning, the motor should not continue to turn with too much swing. 2. has more priority than 3. I have tested the C+ L and XL motor so far. I also have the large angular motor, but it is simply too large. The internal resistance of the C+ L motor was way to high. The C+ XL motor delivered quite ok-ish results. It is just too bulky. Perfect shape and size would be the Medium Angular Motor, which I don't have. Another alternative would be the Boost Medium Linear Motor. I would appreciate, if someone, who has these motors, could do a test for me. A little teaser why I'm looking for this info: I'm building a truck with pneumatic suspension. I using the angles of the suspension arms to detect and control the height. First proof of concept in PoweredUp is already written and working.
