How do you size the market for industrial robotics in small factories?

For SME industrials, I'd start with Census Bureau data (NAICS codes 31-33) filtered by establishment size, then layer in IFR's World Robotics report for penetration rates by sector. Honest truth though — the best signal often comes from primary research: call 20-30 plant managers and ask directly about headcount, pain points, and budget cycles. Combines-bottom-up TAM with real buyer context your client will actually trust.
