Close call. MenteeBot and Optimus Gen 2 trade wins across the matrix.
Readiness, uptime, navigation & connectivity
Price accessibility and ROI clarity
Payload, speed, runtime & labor replacement
Environment fit, footprint & long-term upside
Multi-step warehouse box-picking and packing under 25 kg per unit on dynamic fulfillment lines
Battery cell sorting in high-volume automotive factories (Tesla's own proven use case)
Both are credible picks. Decide on cost and supplier proximity, not capability — the gap is small.
