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
| Metric | Darwin-OP | Unitree G1-Comp |
|---|---|---|
| Investment | $12,000 | $48,900 |
| Payback period | 2.9 mo | 11.7 mo |
| Net savings (5 yr) | $238,000 | $201,100 |
| ROI (5 yr) | +1983% | +411% |
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.
