The following fields had no data for any of the selected robots: Battery / Shift Runtime, Path Accuracy, Cycle Time (25/305/25), MTBF, Vibration Damping, Safety Category, Safety I/O Pairs, E-Stop Response, Safe Zone Count, Digital Twin Support, Communication Protocols, ROS-Industrial Support, Cybersecurity Certs, Predictive Maintenance, Tool Changer (ISO), Warranty, Spare Parts Lead Time
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 | KR 20 R1810 HO | RP4 |
|---|---|---|
| Investment | $26,450 | $25,000 |
| Payback period | 6.3 mo | 6.0 mo |
| Net savings (5 yr) | $223,550 | $225,000 |
| ROI (5 yr) | +845% | +900% |
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.
