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 | Digit V4 | RoboThespian 3 |

| Payback period | 60.0 mo | — |
| Net savings (5 yr) | $0 | — |
| ROI (5 yr) | +0% | — |
RoboThespian 3 has no listed price, so payback can't be computed. Contact the manufacturer for a quote.
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.
