Complete humanoid robots for sale
Pre-owned full-size and tabletop humanoids — research platforms, home units, and developer kits.
Buying a used humanoid is closer to buying a used car than a used laptop: the purchase price is only the beginning. Before you commit, ask for powered-on video of every joint moving through its full range, the robot's total powered hours, and any fault logs. Actuators are the wear item — a robot with 500+ hours on original joints will need a service budget, while a low-hour demo unit is often the best value on the secondhand market.
Compatibility matters more than brand prestige. Check that the software stack you plan to run actually supports the unit's firmware revision — an older research platform locked to a deprecated SDK can cost you months. If the seller can't show you the robot walking, manipulating, or at minimum booting cleanly, treat the listing as a parts donor and price it accordingly.
Expect to pay roughly 40–70% of new price for clean, low-hour units from labs upgrading their fleets; well-worn research robots with known faults trade much lower. Always verify in person or over live video before sending money — HumanoidFlip doesn't handle payments, and neither should a stranger asking for wire transfers.

Buying guide — FAQ
What should I check before buying a used humanoid robot?
Ask for powered-on video of all joints, total powered hours, fault history, and what's included (chargers, batteries, software licenses). Firmware revision matters — make sure your planned software stack supports it.
How much do used humanoid robots cost?
Clean, low-hour units typically trade at 40–70% of new price. Research robots with known faults or high hours go much cheaper and suit parts donors or repair projects.
Can I test a robot before buying?
Yes — and you should. Serious sellers welcome inspections. At minimum, get a live video call showing the robot booting and moving. Never wire money for a robot you've only seen in photos.
Do used robots include software licenses?
Sometimes, but licenses often don't transfer automatically. Confirm with the manufacturer whether the software suite, service plan, or developer access transfers to a new owner before you buy.
