Close call. T800 and walker C trade wins across the matrix.
Readiness, uptime, navigation & connectivity
Price accessibility and ROI clarity
Payload, speed, runtime & labor replacement
Environment fit, footprint & long-term upside
Warehouse order fulfillment — stacking pallets, bin picking, pallet jack replacement in 8-hour night shifts (4-hour battery + swappable module)
International expo pavilions (live deployment at Expo 2025 Osaka as China Pavilion tour guide)
If immediate deployment is the priority, choose walker C. If the goal is to be ready when T800's capabilities mature, track it.
