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 | HTG3 | Rainbow Robotics RB3-730 |
|---|---|---|
| Investment | $115 | $19,250 |
| Payback period | < 1 mo | 4.6 mo |
| Net savings (5 yr) | $249,885 | $230,750 |
| ROI (5 yr) | +217291% | +1199% |
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.
