Buggy Motors with Powered Up
whitepen posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
So I was working on a trophy truck/buggy sort of thing with powered up in Bricklink Studio and I was wondering if it is possible to use a buggy motor with an adapter cable together with the large technic hub or train hub. If someone has the proper components to test this idea out, I would really appreciate it. Here is the sort of thing I am trying to build. -
[MOC] 1:48 Pennsylvania Railroad Q2 Duplex (PF / PU)
Commander Wolf posted a topic in LEGO Train Tech
Hello all, I have recently built a model that might actually deserve a post. This is a working, running (albeit only on R104 curves) 1:48 scale model of the Pennsylvania Railroad Q2 duplex. PF or PU motors power all five driving axles, and the design uses no third party parts besides #11 drivers. See the video for a more detailed description. -
Motorised Johnny 5 MOC <Not an Alternative Build>
RJ BrickBuilds posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
01 by RJ BrickBuilds, on Flickr Hello, Bozos! You can support Johnny 5 on Lego Ideas to turn him into an Official Johnny 5 Lego Set here: Johnny 5 on Lego Ideas Who is Johnny 5? Those who don’t know him, Johnny 5, also known as “S-A-I-N-T Prototype Number 5” or Number 5 for short, is a very lively and inquisitive military robot prototype who’s perpetually hungry for more “input”. He is the star of the 1980’s movies Short Circuit and Short Circuit 2 and a TV special called Hot Cars. He became sentient when he was luckily struck by lightning during a combat demonstration. Although he is designed to serve the military as a robot prototype, he has an adorable child-like behaviour and has a great respect for life. He is a peace-loving robot and refuses to use his military capabilities to harm others. Despite being very intelligent and inventive, his naivety and trusting nature has been taken advantaged of on several occasions. Design This model is fully motorised using Powered Up motors and hub and controlled through a mobile device using the Powered UP App. It uses Technic parts to ensure stability of the structure, and System parts to capture the look and form of Johnny 5. The following are the playable features of the model: Movement – This model can move around on tank tracks and uses skid steer to change directions. Body – Johnny 5’s body can tilt using a Powered Up L motor and controlled using a mobile. Arms – Arms can be raised and lowered individually using the Powered Up App. The fingers can be adjusted manually as well as the elbows. Head – The head can be tilted and turned using the Powered Up App. Eyebrows – Eyebrows can be manually adjusted to suit the desired facial expression. Laser – The laser at the back can be raised and lowered using the Powered Up App. Watch the YouTube video here to illustrate these functions better: Johnny 5 on Youtube Total Pieces: 2,711 Dimensions: Studs: W 68.4 x L 36.1 x H 73.5 Inch: W 21.5 x L 11.4 x H 23.2 cm: W 54.7 x L 28.9 x H 58.8 Weight: 99.8 ounces or 2.83 kg Johnny 5 MOC Pictures: 02 by RJ BrickBuilds, on Flickr 03 by RJ BrickBuilds, on Flickr 06 by RJ BrickBuilds, on Flickr 05 by RJ BrickBuilds, on Flickr 04 by RJ BrickBuilds, on Flickr 07 by RJ BrickBuilds, on Flickr 08 by RJ BrickBuilds, on Flickr 09 by RJ BrickBuilds, on Flickr 10 by RJ BrickBuilds, on Flickr -
Help needed with simple rc program for 51515
whitepen posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
So I was working on a simple rc program on my computer today with my new 51515 set and was trying to make it rc using the keyboard (up arrow=forward down arrow=reverse left arrow=left right arrow=right) But it is hard because there is no "when no key pressed" block to my knowledge. The robot I am using is THIS. Any help would be greatly appreciated. -
6x4 tractor unit inspired by Scania
functionalTechnic posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi guys Recently, I finished another model. It is a tractor unit inspired by Scania S-Series trucks. It has 6x4 drive and suspended axles. The front axle is suspended with normal LEGO hard shock absorbers. The rear axles have rubber suspension which imitates air-suspension as used in real trucks. The suspension at the rear axles is a bit hard but chassis is in return flat. The fifth wheel as a self-locking mechanism so that you can couple a trailer easily. To open the fifth wheel a small linear actuator is used. For steering a PU L motor sits directly on the front axle. For propulsion I used two PU XL motors. But check the pictures and video: Instruction at Rebrickable: https://rebrickable.com/mocs/MOC-86508/FT-creations/6x4-tractor-unit-inspired-by-scania/#details -

It will depend on your current collection and your future plans but the facts to make your own decision are there. Robot inventor 51515 is a bird of different fur, so I am not considering here, but could be a possibility for some. -

buwizz 3 and PU hub app
iTZiX posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi, new here, need some help, I'm searching for an app that can control buwizz 3 and the PU hub, at the moment I can control the buwizz via their official app and control the hub with the BrickController2, but not both using one app. hope there is an app that can do that. thank you. -
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?

I'm missing a place where Powered Up code can be gathered and explained so other guys can reuse it or find inspiration. I had a discussion with @Jim how that could work out in this forum. I was thinking about having something like the hall of fame for code which underwent optimizations in a dedicated thread and which was proven to work. But this might lead to several thread which are prone to be inactive. So we decided to start with a single thread to publish PU code and discuss it. If it gets to chaotic We could have two separate thread. One for discussion and help request and the other one for working and optimized code. To keep things orderly, a general structure might be helpful. So here we start with my proposal. TL;DR: Automatic brake lights based on speed reduction Description: The following code switches brakes lights on in case the speed is reduced. That works for reducing speed while driving forward and backward. When the speed reaches 0, the light are turned off. In this code I'm using PF lights controlled by the Boost color and distance sensor. But that can be replaced with PU lights. Code: Video Declaration of variables: a - Used to control the speed, is set by the slider 0 b - Speed (a) at the first point in time c - Speed (a) at the second point in time d - Speed difference between b and c Detailed walkthrough: The code block consists of three rows. The first row consists of a loop (left) and the code block to control the speed of the motor (right). Most of the code blocks in the loop are not needed. You actually just need the first block which sets constantly a value for the variable a to control the speed. The rest are widgets for testing timings. The second row is the logic to detect speed differences. To do that constantly, a loop is used again. It simply reads a, the speed at different times. You can adjust the time between the measurments according to your needs. In my case 0,08s worked well. At the end of the loop the difference is set to the variable d. The value can be something between 100 and -100. The third loop at the bottom contains the logic to turn the brake lights on or off. You will also notice the purple blocks. They are used to control the PF lights. I'll come to that in a bit. First i want to explain the logic to turn the lights off an on. There are three scenarios: Driving forwards Driving backwards Parking When you are driving forward the max value of a is 100. Lets say the speed is suddenly reduced to 50. The difference is 50. When you are driving backwards the max value for a is -100. The speed is again reduced by 50. The difference is -50. When you are parking the difference is of course 0, because it doesn't change. So i have two condition i want to check for: Am I driving backwards or forwards? Is there a speed difference? I can exclude the third check, parking, by checking values for a that are greater or smaller than 0. So, in one sentence: IF there is a speed difference AND the speed is GREATER THAN 0 OR IF there is a speed difference AND the speed is SMALLER THAN 0 then turn on the light (upper purple block at the end). But how to control PF lights with Powered UP??? That is covered for example by @kbalage here. The first purple code block on the left sets the port and the correct mode for the boost sensor. The two purple code blocks on the right side control the brightness of the PF lights. D is the port where the sensor is connected to, 3 is the channel 4 on the PF IR receiver, 5 is the red or blue port on the IR receiver, 7 switches the light to max brightness, 8 turns it off. -
European 8x4 Dump Truck inspired by Scania
functionalTechnic posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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)
