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 | Little Sophia | STEM Boat |
|---|---|---|
| Investment | $249 | $4,999 |
| Payback period | < 1 mo | 1.2 mo |
| Net savings (5 yr) | $249,751 | $245,001 |
| ROI (5 yr) | +100302% | +4901% |
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.
