Insufficient data for full comparison
The following fields had no data for any of the selected robots: Payload (Peak), Arm DOF, Hand DOF, Grip Strength, Battery Capacity, Charging Time, Avg Power Consumption, Fall Detection Response, Emergency Stops, Simulation Platforms, MTBF, Task Success Rate, IP Rating, Noise Level, RaaS / Month, Developer Unit Price, Delivery Lead Time, Warranty
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 | AlphaBot 2 | SA01 |
|---|---|---|
| Investment | No price | $5,744 |
| Payback period | — | 1.4 mo |
| Net savings (5 yr) | — | $244,257 |
| ROI (5 yr) | — | +4253% |
AlphaBot 2 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.
