Show HN: Agents infer Lego mechanisms from sources, then animate them
Hi there :)
Around a month ago, I released LDraw Nova, an agentic toolset for assembling LEGO CAD models by generating LDraw source code files.
For more details, here's the Show HN post:
news.ycombinator.com
From the comments, I got the impression that there was quite an interest in seeing not only AI-generated LEGO models, but also AI-animated LEGO ones.
I took a look at results from past experiments, and found it feasible to use agentic LLMs for:
- analyzing the LDraw source code for LEGO models
- reverse-engineer! the mechanisms present by reading the descriptions and sequence for the parts there
- and then, animate them via Blender!
This new project I'm presenting, LDraw Mecha, is the end result and proof that can be done:
- Read specially annotated LDraw LEGO models .mpd source files
- Infer the model structure in terms of submodels
- Select from those the ones that are mechanisms
- Plan animations
- Execute them in Blender
In summary, from an initial .mpd source file, get a rigged and animated version for the model as a Blender (.blend) file.
See the results here:
- Repo (v0.5.0): github.com/anteloc/ldraw-mecha/tree/v0.5.0
- Gallery: github.com/anteloc/ldraw-mecha/blob/v0.5.0/GALLER…
- Process: github.com/anteloc/ldraw-mecha/blob/v0.5.0/PROCES…
This project is very unusual, I'd really appreciate some feedback from the community.
Cheers!

I made it work without the jev API with llama-server (d1-3b + qwen 4b rerank)
