The display does not start
Check power and the installed board target. With power disconnected, inspect the display cable and connector lock. Check the round display connection and the firmware configuration for this model.
Network discovery fails
Confirm that the robot is in provisioning mode, Bluetooth permission is granted and the Wi-Fi network is 2.4 GHz. Verify that the app matches the firmware region. See Wi-Fi and activation.
Voice commands do not respond
Check the region-specific wake word, online state, microphone and current operating mode. Exit BLE remote-control mode if voice services have been suspended. A network connection alone does not confirm cloud activation.
Motion is irregular
Stop testing. Check battery charge, cable connections, component orientation and calibration. Inspect the complete joint path and cable slack. A teach recording is lost after restarting; record again before replay.
What should I include in a support request?
Record the model, hardware revision, firmware version and region. Describe the steps that reproduce the issue, screen message and whether it happens before or after network connection. Include a photo of the assembled mechanism or a short startup log where useful.
