Possible Causes

LiDAR turret blocked by dust or object, LiDAR motor not spinning, LiDAR cable loose, Failed LiDAR sensor module

How to Fix / Troubleshooting

Safety first: Turn off the robot and avoid touching the LiDAR window with sharp objects.

Check LiDAR turret:

  • Inspect the rotating LiDAR tower on top of the robot (if your Tesvor model has one). Ensure nothing is resting on it or blocking its rotation.
  • Gently blow away dust from the LiDAR window using compressed air or a soft brush.

Test rotation:

  • Power on the robot and listen closely: the LiDAR turret should spin quietly when the robot starts mapping.
  • If it does not spin or makes grinding noises, the LiDAR motor may be jammed or failed.

If cleaning does not help: The LiDAR module or its cable may be defective. Because LiDAR alignment is critical, replacement should be done by a qualified technician. Do not disassemble the LiDAR unit itself.
