Trade task demonstrations
Bricklaying, rebar tying, welding, material transport, scaffolding, and finishing — recorded first-person on live Indian construction sites.
Physical AI data
Construction data for physical AI.
Task demonstrations from live construction sites and engineering drawing datasets — documented, consent-verified, drawing-linked. From the team behind SteelBox's drawing intelligence.
What we collect
Real site work, captured with engineering context.
Drawing-linked annotation
BIM registration, weld-path and assembly-state labels generated at source by our drawing-intelligence stack, not after-the-fact manual labeling.
Site environment data
Diverse real-world conditions: dense urban sites, monsoon weather, low light, mixed machinery, active logistics.
Why teams partner with us
Access, consent and engineering accuracy built in.
- Signed site access through our contractor network across Eastern India (Kolkata, West Bengal).
- Written bilingual consent (Bengali + English) and DPDP Act 2023-aware audit trails on every capture.
- Engineering-native team: we read structural drawings (SteelBox), so task specs and annotations are correct by construction, not by guesswork.
- Pilot batches deliverable within 2–3 weeks of spec alignment; scaling to thousands of hours.
Teams building robots for the built environment.
Construction robotics companies, robot foundation-model labs, and research teams building manipulation policies for the built environment.

Provenance ships with every dataset.
Every dataset ships with provenance documentation — collection conditions, consent records, and annotation methodology — suitable for EU AI Act-style provenance requirements.
