ABB IRB-4600, RML63 have 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.
