“Fuse first, then fault‑find,” muttered Pedro, who’d learned the hard way. His apprentice, Iva, slid into the vocational twin, where the classroom smelled faintly of ozone and warm plastic – minus the risk. “Try the ring circuit,” said HAL8122™. The phantom tripped. “Hear that buzz? That’s a loose neutral.”
Regional training centres must deliver job‑ready skills fast – without burning budgets or fingers. Equipment is scarce, schedules are tight, and learners vary wildly in confidence.
How it Works: Workshops are scanned into the twin with LiDAR and photogrammetry; physics and fault models make sockets sing or sulk. HAL becomes a safety coach: it adapts scenarios to each learner, pauses risky moves, asks reflective questions, and logs mastery against modular credentials. Instructors drop in from anywhere to co‑coach; employers preview cohorts in a fair, skills‑first way. When learners hit the real bench, AR overlays mirror the exact steps drilled in the twin.
Why it Matters: Confidence climbs; near‑misses fall. Centres stretch limited kits further; employers trust badges because they map to rehearsed tasks, not generic checkboxes. Iva’s first day on site feels like day ten – because she’s already done the dance.
EU‑by‑Design: Minimal personal data, clear consent for performance analytics, explainable AI tutoring aligned with the AI Act spirit, and accessible design for dyslexia, colour vision and motor differences. Assessment is fair, not fuzzy.
