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

ROI (5 yr)	—	+355%

ibuki 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.
