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.
New Powered Up system
Niedzwiedzmin posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHello everyone, I was trying to figure the below down on my own browsing forums, searching for answers, reading a lot of articles from last 2 years however I did not find strict answers to my questions. I am sorry if some answers were already posted here and I did not find them. As I am about to spend some serious money (for me personally as I am not rich) on Lego Technic and I want to be able to create custom machines later I feel like I HAVE TO decide between Power Functions and Powered Up. 1. Is (or will) Powered Up system be customizable using Lego official App or 3rd party app? Will I be able to use Power Up motors and customize them into different than original machine so it works? 2. Should I even be coinsidering Powered Up systems for future and creating custom machines? 3. Is Power Functions a better choice for now and for future for creating custom machines? Is it easier to customize controls? 4. Are there any news or leaks that Lego will allow to customize controls of new Powered Up motors? 5. Is Power Functions better for building custom machines than Powered Up? 6. Does BuWizz or Bricks going to support and customize Powered Up? I am sorry, it all feels so overwhelming as for a beginning person that has limited budget and needs to pick carefully and plan everything ahead.
