ROI Comparison

Same operating assumptions across every robot — the only difference is price. Set your numbers once to see which pays back fastest.

Robots (fleet)

Annual labor displaced (per robot): $50,000

Metric	OT-2	PR1
Investment	$15,950	$50,000
Payback period	3.8 mo	12.0 mo
Net savings (5 yr)	$234,050	$200,000
ROI (5 yr)	+1467%	+400%

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.
