Possible Causes

LDS motor not spinning, LDS cable disconnected, LDS sensor internal failure, Impact damage to LDS turret

How to Fix / Troubleshooting

Safety first: Power off the robot and avoid looking directly into the LDS laser aperture.

Step-by-step:

  • Check for physical damage: Inspect the LDS turret for cracks, dents, or signs of impact.
  • Clean around turret: Use a soft cloth to clean the turret window and remove dust from the gap.
  • Power cycle: Turn the robot off for 1–2 minutes, then back on. Listen for a faint whirring sound from the turret when it starts; this indicates the motor is spinning.

If the turret does not spin or the error persists: The LDS module or its motor is likely defective. Replacement requires opening the top cover, disconnecting the LDS cable, and installing a new module. This is an advanced repair; professional service is recommended.
