The following fields had no data for any of the selected robots: Battery / Shift Runtime, Path Accuracy, Max TCP Speed, Cycle Time (25/305/25), MTBF, Vibration Damping, Safety Category, Dual Check Safety, Safety I/O Pairs, E-Stop Response, Safe Zone Count, Communication Protocols, Cybersecurity Certs, Predictive Maintenance, Pneumatic Lines, Electrical Lines, Spare Parts Lead Time, Expected Service Life
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 120 R3900-2 K | KR 700 PA |
|---|---|---|
| Investment | $51,950 | $49,500 |
| Payback period | 12.5 mo | 11.9 mo |
| Net savings (5 yr) | $198,050 | $200,500 |
| ROI (5 yr) | +381% | +405% |
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.
