UBTECH walker S2 leads on 4 of 7 dimensions — strongest on ROI clarity.
Readiness, uptime, navigation & connectivity
Price accessibility and ROI clarity
Payload, speed, runtime & labor replacement
Environment fit, footprint & long-term upside
Circuit board inspection and barcode scanning on production lines (confirmed December 2024 deployment)
BYD-scale EV door-lock inspection on 500+ daily units, 24/7 across two shifts
Both are credible picks. Decide on cost and supplier proximity, not capability — the gap is small.
