- Unitree states this is a civilian robot. No public price or dealer listing found on 2026-10-17; the status 'limited' reflects order-by-enquiry sale, not confirmed stock.
- Payload row of the official table is a single merged cell covering both columns (40 kg continuous, 70 kg maximum), and the Inspection Solution endurance is quoted at 40 kg payload, so the 40 kg is kept for both variants. Slope: 45 degrees (chassis) / 30 degrees (Inspection Solution).
