The following fields had no data for any of the selected robots: Running Capable, Payload (Peak), Arm Reach, Grip Strength, Manipulation Repeatability, Tool Use, Teleoperation, Battery Capacity, Charging Time, Charging Method, Avg Power Consumption, Force-Limited Arms, Fall Recovery, Fall Detection Response, Emergency Stops, Safe Speed Near Humans, Simulation Platforms, Air-Gap Capable, MTBF, Task Success Rate, IP Rating, Noise Level, RaaS / Month, Developer Unit Price, Delivery Lead Time, Warranty, 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 | AlexBot | HRP-4 |
|---|---|---|
| Investment | $4,298 | $302,500 |
| Payback period | 1.0 mo | 72.6 mo |
| Net savings (5 yr) | $245,702 | -$52,500 |
| ROI (5 yr) | +5717% | -17% |
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.
