Close call. Apollo and S1 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 and logistics box/tote picking and transport (primary focus; proven in GXO trials).
Battery cell assembly on CATL production lines with repetitive 30–50 kg transfer cycles.
Both are credible picks. Decide on cost and supplier proximity, not capability — the gap is small.
