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 | PR2 | Robbyant R1 |
|---|---|---|
| Investment | $400,000 | $55,000 |
| Payback period | 96.0 mo | 13.2 mo |
| Net savings (5 yr) | -$150,000 | $195,000 |
| ROI (5 yr) | -38% | +355% |
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.
