Insufficient data for full comparison
The following fields had no data for any of the selected robots: Battery / Shift Runtime, TCP Speed (Collaborative), Power/Force Limiting, Safety I/O Pairs, Time to Redeploy, Tool Changer Support, Integrated F/T Sensor, MTBF, Path Accuracy, CaaS / Month, Lead Time
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 | AUBO-i20 | Rainbow Robotics RB3-730 |
|---|---|---|
| Investment | No price | $19,250 |
| Payback period | — | 4.6 mo |
| Net savings (5 yr) | — | $230,750 |
| ROI (5 yr) | — | +1199% |
AUBO-i20 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.
