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 | 400kg Light | Proteus |
|---|---|---|
| Investment | $25,000 | No price |
| Payback period | 6.0 mo | — |
| Net savings (5 yr) | $225,000 | — |
| ROI (5 yr) | +900% | — |
Proteus 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.
