LeoCAD: Assemblies, reference models & parts...
The LDraw system uses a hierarchical structure where files reference one another to build complexity. So creating a single (large) object, like a big building, this system works well. Depending on complexity, 'sub models' could be used for different reasons: For the most objects this works well. But how to create an assembly, containing: Method […]
Showing 3D models online, created by LeoCAD...
Would be great to export 3D models from LeoCAD and show them on online platform(s). I did investigate already some different online platforms and SketchFab seems to be best for now. So let's test a relative big LeoCAD building: Mobaco construction toy library (v1.5), instruction Set 5-C: While exporting the model, the next features are […]
Mobile robot platform
Finaly a workable mobile robot platform! Hello, I’m back working on "Pico Smart Car DIY" again. With the help of ChatGPT and reading even more articles on the internet, the complete software architecture of the robot is changed! It's finally possible to send waypoint by remote PC and leave the movements to the robot: The […]
Online 3D model viewers...
Creating those LeoCAD 3D buildings/structures, will be more appealing, when viewed inside a 3D viewer, so it's time for some coding.Since glTF is "the standard 3D format" for internet and could even include animations, this seems a good direction to try. Converting LeoCAD to glTF With a bit of help from ChatGPT, managed writing some […]
DuckieTown
It's time to continue with the MOOC DuckieTown course and build the newest DB21J (4GB) DuckieBot. Although I did consider buying an older (& cheaper) RPi version, the newest version should be less stress full, since it (should) work with the newest online course. First impressions: Road & tiles... I decided to create the road-tiles […]
Pi Wars 2024 - Distaster zone
Ever heard about Pi Wars? Pi Wars is a non-destructive, Raspberry Pi-based robotics competition with both autonomous and remote-controlled challenges. It takes place in-person over a single weekend and features teams of school students, families and hobbyists as well as solo roboteers. The event open to anyone on planet Earth! I joint a small group in The […]
Retro Building Toys
Around April 2021 I came in contact with a small group of enthousiasts, who were investigating an old Dutch made construction toy called: Mobaco (1924-1956). After reading some posts & discussions, I wanted to anticipate to this research, but from a bit different angle: Why not make this building toy available in 3D, so everyone […]
