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 R1 |
|---|---|---|
| Investment | $12,000 | $5,900 |
| Payback period | 2.9 mo | 1.4 mo |
| Net savings (5 yr) | $238,000 | $244,100 |
| ROI (5 yr) | +1983% | +4137% |
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.
