Quick answers
What is wrong?
Motion stops unexpectedly via external e-stop wiring, or stand/lie button timing confuses operators.
What you might notice
- Sudden stop
- Stand/lie delayed after press
- External STOP line active
Can I fix this myself?
Usually yes for the checks below. Difficulty: easy · about 5-10 min. If unsafe or unresolved, use meetup / mail-in repair.
What you need
- R1 interface panel documentation
Do this
- Check the top electrical interface: Unitree documents a Stand up / Lie down button (action runs ~3 s after the voice prompt) and an external e-stop connector (STOP / NC / GND).
- Confirm nobody latched an external STOP line and that accessories on 24 V / 36 V outputs are within rated current.
- Clear the area, release e-stop if safe, and re-try stand/lie only on flat open floor.
- If stops repeat with e-stop clear, capture LED/app state and request assessment — do not bypass safety wiring.
Parts (only if cleaning fails)
- None for a basic check
