Possible Causes

Loose battery connector, Internal wiring harness partially unplugged, Failing power switch, Mainboard solder joint issues

How to Fix / Troubleshooting

Safety first: Turn OFF the robot and remove it from the dock.

Check battery connection:

  • Open the battery compartment and ensure the connector is fully inserted and not loose.
  • Inspect the battery wires for damage or pinching.

Observe behavior:

  • With the robot upside down and powered ON, gently tap the body near the battery and mainboard area. If it shuts off, there is likely a loose connection.

Advanced: Internal harnesses or the power switch may need reseating or replacement, which requires opening the chassis. This should be done by a technician to avoid damaging the mainboard.
