ROI Comparison

Same operating assumptions across every robot — the only difference is price. Set your numbers once to see which pays back fastest.

Annual labor displaced (per robot): $50,000

Metric4NE-1Darwin-OP
Investment$63,250$12,000
Payback period15.2 mo2.9 mo
Net savings (5 yr)$186,750$238,000
ROI (5 yr)+295%+1983%

Estimates labor-cost displacement only — not a full total cost of ownership. Actual ROI depends on integration, maintenance, training, downtime, and task fit. Converted currencies are indicative; USD is the price of record.
