How to Fix / Troubleshooting

Safety first: Turn off the robot and flip it over.

Identify the side:

  • Manually rotate each drive wheel and listen for grinding or clicking.
  • Check the tire for cuts, flat spots, or objects stuck in the tread.

Advanced repair:

  • Remove the bottom cover to access the noisy wheel module.
  • On many Tesvor models, the wheel module is a sealed unit; if gears are damaged, replace the entire module.

After replacement: Reassemble the robot, ensuring all connectors are secure, and test movement on a flat floor.
