Insufficient data for full comparison
The following fields had no data for any of the selected robots: Payload (Peak), Arm Reach, Grip Strength, Manipulation Repeatability, Tool Use, Teleoperation, Avg Power Consumption, Force-Limited Arms, Fall Recovery, Fall Detection Response, Emergency Stops, Safe Speed Near Humans, Air-Gap Capable, MTBF, Task Success Rate, IP Rating, Noise Level, RaaS / Month, Developer Unit Price, Production Pilots
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 | A2-W | Unitree R1 Base |
|---|---|---|
| Investment | $145,000 | $5,400 |
| Payback period | 34.8 mo | 1.3 mo |
| Net savings (5 yr) | $105,000 | $244,600 |
| ROI (5 yr) | +72% | +4530% |
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.
