Close call. S1 and T800 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
Research labs testing whole-body imitation learning and mobile manipulation under controlled conditions
Warehouse order fulfillment — stacking pallets, bin picking, pallet jack replacement in 8-hour night shifts (4-hour battery + swappable module)
If immediate deployment is the priority, choose S1. If the goal is to be ready when T800's capabilities mature, track it.
