Unitree G1 Error Codes

No public error-code reference has been published for the Unitree G1. Unitree hasn't released fault tables, diagnostic-code lists, or troubleshooting flowcharts — so there's no official document to link to, and we won't invent codes.

What we can tell you from owner experience: most humanoid faults cluster in a few families — joint torque faults under load, battery/charging faults, IMU and sensor errors, and communication dropouts between joint controllers. The setup notes below describe the failure modes actually reported for this model.

Unbox on a clear, flat surface with at least 2 meters of clearance — the G1 ships in a flight case with the charger, a spare battery, and developer docs. Charge both batteries fully before first boot; a partial charge is the most common cause of a failed first startup.

Work through the official quick-start in order: power-on sequence, remote-control pairing, then the guided first-stand. Don't skip the waist-fastener check described in the docs — it's a small step that prevents an embarrassing first fall. When you're comfortable, the SDK section covers voice assistant setup and sport-mode gaits.
