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 | ROBOTERA L7 | Walker S2 |
|---|---|---|
| Investment | $118,500 | $207,140 |
| Payback period | 28.4 mo | 49.7 mo |
| Net savings (5 yr) | $131,501 | $42,860 |
| ROI (5 yr) | +111% | +21% |
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.
