Madrid '26 · THEKER track

XFOLD

A team project from HackSpain 2026 in Madrid. A shirt rides a belt through a press, a flap folder, a bagger and a seal station, all in simulated physics, and every run streams to a control room you can watch live or replay.

Product

What I focused on

Within a team that worked closely all weekend, I built the Next.js control room and the Python bridge between it and the simulation: an append-only run journal, REST for commands, SSE for live events, and the integration contract that let the physics and UI sides work in parallel. Also experiment persistence in SQLite, the live console and the XFOLD branding.

Capabilities

Deformable cloth simulation on MuJoCo and Isaac Sim / PhysX
Control-room dashboard with live view, replay and measurements
Run journal over REST and SSE, with per-run video
Camera-based fold-quality score for every cycle

Build notes

Folding shirts at HackSpain 36 hours, one robotics brief from THEKER, and a simulated line that presses, folds and bags shirts. What we built and how the weekend went.
