Frequently asked questions
Is it safe to buy a used humanoid robot?+
It can be, if you verify. Always inspect the robot in person or over a live video call before paying: check joint movement, battery health, and firmware version. Ask for the unit's runtime hours and service history. HumanoidFlip connects you directly with sellers — never wire money to someone you haven't verified.
How much does a used humanoid robot cost?+
Prices vary widely by platform and condition. Smaller research units like a used Unitree G1 typically list around $10k–$16k, while full-size platforms like the Unitree H1 or Agibot Raise A2 run $30k–$70k. Components — actuators, dexterous hands, sensors — start in the hundreds. Browse live listings to see current asking prices.
What should I check before buying a pre-owned humanoid?+
Runtime hours, battery cycle count, joint torque calibration, cosmetic damage that could hint at drops, and whether the firmware is up to date. For lab units, ask why it's being sold — upgrades and cancelled pilots are the most common (and healthiest) reasons. Request a live demo of locomotion and manipulation before committing.
Does HumanoidFlip charge fees or handle payments?+
No. Listing is free and there's no platform cut — buyers and sellers deal directly. HumanoidFlip doesn't handle payments or escrow yet, which is exactly why we stress verification: inspect in person or over video, and never send money to strangers.
