[WIP] Lexus LC500
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Here is a quick summary of a previous post. Right now I'm planning on a new project and I could use some help. It's a 1:8 scale model of Lexus' LC coupe powered by Lego Mindstorms EV3. Currently, I have the rear axle built off the instructions from the Porsche 911 GT3 RS set. I also made the engine for the LC500 on Lego Digital Designer and I am wondering if it is good enough to buy the pieces for it on BrickLink. I also want to add the following features: Four or six-speed paddle-shift transmission Retractable spoiler Detailed interior Fake V8 engine (but I would like to achieve moving pistons) Full independent suspension I would welcome some helpful comments about the V8 engine, axles, and the gearbox I planned to use before I order pieces on BL. Thank you. -
[WIP] Lexus LC500 EV3 1:8
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This is my first WIP post on EuroBricks where I will show my progress on my newest build, an EV3-powered 1:8 replica of Lexus' newest flagship coupe, the LC500. The car will most likely be a combination of both the standard and the V6 hybrid LC, but it will have a V8. The body will also be orange. Here's a photo I found of an LC that looks a lot like the one I am shooting for. Features I'm planning to add: Four or six-speed paddle-shift transmission Retractable spoiler Detailed interior Fake V8 engine (but I would like to achieve moving pistons) Full independent suspension All I built so far was the rear axle for the LC. It's exactly like the one in the Porsche 911 GT3 RS set but more reinforced. I also made the V8 engine using Lego Digital Designer. I plan to build the paddle-shifting mechanism used in Didumos' Ultimately Playable Porsche 911 GT3 RS (the one with the tilted wheel) and pair it up with a gearbox. I currently am having trouble whether to motorize his gearbox with the EV3 motors or to pick a different one with less gears and friction. I also am having a little bit of trouble finding the right front axle, though I like the one that Didumos put his Porsche because of the fact that is has two shocks for each wheel. However, I find it very difficult to fit the V8 engine in the middle since the axle is made for a rear-engine car. Here's a poorly drawn render I made of what I'm trying to achieve with the front axle. And here's the chassis in the real LC and the measurements for the LC Lego model. Overall, I'm excited about the build. I would welcome some helpful comments about the V8 engine, axles, and the gearbox I planned to use before I order pieces on BL. Once I start working on the body and aesthetics, I would appreciate some input with that as well. I can also give you the download for the .lxf file of the engine if you'd like to check it out. I look forward to replying to your comments and sharing my progress. Thank you. -
Beginner Car Chassis - Lego Mindstorms EV3
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This is my simple Lego car chassis for Mindstorms and Technic beginners. Features Rack-and-pinion steering Full independent suspension 1:3 gear ratio driven to rear differential I built this chassis as both an experimental project but also an educational one to not just me but people starting to make their own cars with Mindstorms and Technic. If you're looking for a chassis design that may work for the build you're creating (a sports car, sedan, or small truck) then I hope this helps you and I would look forward to seeing the finished result. -
ASSAULT3R: An EV3 Assault Vehicle
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This is ASSAULT3R, a Lego Mindstorms EV3 Assault Vehicle. After getting a second Lego EV3 set, I knew that I had to build something awesome. Features RWD and Steering Ultrasonic Sensor Infrared Sensor Two Color Sensors Dual Ball Shooters Gullwing Doors Detailed Interior and Exterior The ASSAULT3R's front sports red lights that will strike fear in enemies and their machines. Its dual ball shooters will shoot a total of six Lego balls, three for each side, high or low. That's twice the weaponry used by EV3RSTORM. The gullwing doors allow easy access for operators and it makes the ASSAULT3R look futuristic yet sinister. I had a lot of fun building this, and I'm very happy with the result. And of course, here are some photos as always. -
Stanced Porsche 911 GT3 RS
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This is the second mod I have done to Lego's 42056 Porsche 911 GT3 RS set. I used the same height lift as I used on my previous Porsche mod and moved forward the bottom arms in the front and the rear of the chassis to add negative camber. The car was able to roll without the body on, but once I put it on, it couldn't roll. This means the car is now purely a display model. As much as a JDM fanboy I am, I'm kind of upset with the result of the car not moving, but at least I'm glad that I stanced this car anyways just for the fun of it. Although, quote automotive YouTuber GasKings, the camber angle does seem a bit too much on here like "a baby giraffe taking its first steps." So, what do you think of this mod I have done? Is it CamberGang worthy? I think it looks neat, but I would like to get rid of the camber (and the height lift) so I can roll this car around again. Here's some more pictures of the car I took. Thanks as always for checking this out, and I hope you'll stick around for my next builds. -
Winter-Ready Porsche 911 GT3 RS
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
This is Lego's 42056 Porsche 911 GT3 RS set with some unique rallycross-inspired features I added making it the perfect sports car to drive in the snow. Features Suspension system raised to make the car about two studs higher Wheels and tires from the 42037 Formula Off-Roader Mudflaps LED light bar Front off-road lights Rear bash bars Optional snowplow that attaches to the front The lights are fake and don't turn on, and all of the other lime-colored pieces are from the 42037 set as well. I had a lot of fun making this. I just had to switch of the area of the springs to change the height for the rear without any pieces needed, but for the front, I had to remove the entire Porsche's body to make the lift there using a variety of pieces. Overall, I'm proud that a got the result I wanted, which was making the Porsche 911 GT3 RS higher (so it wouldn't bottom out) and equipping it with off-road features so I could have fun with this set in the winter. It does need to drive in snow only about an inch high so I could move it without getting stuck (and so the plow can move the snow too). I recommend to anyone who has the Porsche set to try these mods out for themselves this winter! Here's some more pictures of the car and a desktop wallpaper that I created wishing everyone at EuroBricks Happy Holidays! -
I know I normally post stuff on the forums about Lego Technic, but I also enjoy building Lego MineCraft sets as well and connecting them together. Today, I looked at my The First Night set and noticed something very odd. I got the set on Christmas Eve 2015, and I never noticed this problem the entire time I had it. This is Lego's official picture for the set. Focus on the green 2x2 plate with knob above the brown 2x2 brick with the rose on the right of the pig. When you build the set, the instructions show that there is no green plate below the rose. I don't think there is even a spare piece for it. I checked the internet and I believe nobody ever noticed this before. I'm perfectly fine with it though, since everyone occasionally makes mistakes. What do you think? Has anyone here saw this mistake before?

"The Pursuit of Perfection" - slogan of the Lexus brand. I'm now back with my greatest Lego creation ever. A 2010 Lexus GX 460 with EV3. It's a replica of my Dad's car, but this one's in gray with black interior. I made it as much as I could to the real car, thanks to pieces from the Arocs and Porsche set. Features Sariel's 4-speed sequential gearbox controlled by a medium motor All-wheel-drive Independent suspension Rack-and-pinion steering Fake V8 engine Six seats (could not fit a seventh one) with the rear four being foldable Opening side doors, trunk door, and hood. Detailed interior The gearbox and the two differentials in the car like to click while moving (especially on rough terrain) around, but the result was a car that was heavy, slow, but also makes lots of torque. I'm very happy with how this car came out and I couldn't have done it without all of the helpful people on the Lego community and EuroBricks. Thanks especially to my good friend TheMindGarage for never making me give up. Now I can officially call myself a true master builder. Check out this build on my EV3 community account too for more photos and information about it. I would love to make a YouTube video soon about the features of the GX EV3 and footage of me taking this build on some dirt trails in a park. I also want to take a picture of this right next to my Dad's actual car. So please follow this post to check out some stuff I might upload in the future! To finish this post, here's some collages with photos of the GX EV3.

Need Help Making Heavy AWD SUV Move Better
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I'm back with one last issue in my GX EV3 build. I just got done finishing the doors, side panels, rear trunk door, hood, and some part of the roof. But the vehicle was so heavy that when I drove it around, it kept on doing the same thing. The diffs were clicking and the car had very much difficulty moving. Here is a picture of the bottom of the vehicle. Most of the clicking seems to be coming from the rear diff when I move the wheels by hand. I can either do two things. 1. Reinforce the rear diff somehow. 2. Improve it's off-road performance and stop the clicking somewhat by replacing the diffs with knob gears. But this will come at the cost of independent moving between the wheels. What should I do? Please give me the best response you can so the clicking will stop and I could finally take this AWD machine through some rough terrain like a real SUV. I really appreciate any advice. -
Help With EV3 Remote Control Program
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I'm programming my EV3 vehicle to be operated by an IR beacon remote. I've successfully got the car to be able to move, but I'm stuck on something else. My vehicle has a 4-speed transmission, and a medium motor shifts the gears. I used the remote's topmost button (the one that turns on the green light on the remote) for shifting the gearbox. But when I press it, something goes off. It's really hard to say, but what I know is that the topmost button isn't acting like a normal button. So the motor keeps on moving until the IR sensor realizes the green light is off. I really need help with the program because I just want the topmost button to act like a normal button so I can press it to make the medium motor shift one gear with a one second wait before shifting to the next one. I would love a very helpful response from someone that knows how to program the IR remote and if there is no way to get the topmost button to get the result I want, an alternative would be nice so I can be able to shift gears with the push of a button on the remote. -
Gear Grinding in Differentials (EV3)
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I said before in my previous post that I had some problems with my GX EV3 4x4 chassis that I needed to fix. Once again, it's more gear grinding/clicking, but this time it's only in the front and rear differential gears. The grinding occurs whenever the chassis tries to drive into a wall or when it tries to drive in different conditions (because as an SUV it should drive smoothly in dirt or uneven terrain). What also annoys me is that when I push the car, instead of letting the motors move, the differentials make clicking noises that, like I said before, sound like a machine gun. I really need help so I can stop the differentials from clicking so when the car tries to drive into the walls, the motors won't still move while the differentials click, and so the car can be a lot more versatile on uneven terrain (such as what I used for testing, blankets) without the differentials causing a problem when the car moves. Here's some pictures of the bottom of the chassis. -
More Gear Grinding/Clicking in Gearbox (EV3)
StudRobotics posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I'm back again with another gear grinding issue but this one is a bit less critical. The grinding only occurs when my 4x4 SUV chassis (with Sariel's 4-Speed Sequential Transmission) is in a certain gear. Here's some photos of the chassis. The transmission is shifted to the speed where the nonstop grinding occurs. When in this gear (I believe it may be 3rd) The car is supposed to move, but it does very slowly while clicking noises fire like a machine gun. This is the only time when the gears grind other than, say, if the chassis hits a wall. When the clicking begins, I hear the driving rings shake (which awfully reminds me of the somewhat gear clicking in the Mercedes-Benz Arocs set). I would love a response a soon as possible to address the clicking problem so I can finish the chassis once and for all.
