The secondhand humanoid market is growing fast — and so is the risk of buying someone else's problems. A pre-purchase inspection is a professional evaluation of a used robot before money changes hands: mechanical health, battery condition, actuator wear, sensor function, and software/firmware state.
The inspection typically takes 1–2 hours and produces a written report: what's healthy, what's worn, what's likely to need replacement soon, and a fair-value assessment. For robots in the $10,000+ range, it's the cheapest insurance you can buy — one avoided bad purchase pays for dozens of inspections.
If the seller won't allow an inspection, treat that as information. Legitimate sellers welcome it.

Typically a few hundred dollars — a fraction of the purchase price. Complex or large robots can run higher.
A video walkthrough catches obvious issues, but the real value is hands-on: joint play, battery testing, and motion validation need physical access.
We can often coordinate with a technician near the seller — mention the location when you request.
