UBTECH walker S2 leads on 3 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
Electronics assembly where force feedback prevents part damage
BYD-scale EV door-lock inspection on 500+ daily units, 24/7 across two shifts
