Annual labor displaced (per robot): $50,000
| Metric | CSK04-KJ 400kg Payload Industrial AMR | S-series sort |
|---|---|---|
| Investment | $25,000 | $7,900 |
| Payback period | 6.0 mo | 1.9 mo |
| Net savings (5 yr) | $225,000 | $242,100 |
| ROI (5 yr) | +900% | +3065% |
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.
