How to Fix / Troubleshooting
Danger: This is a critical safety fault. Do not operate the robot until resolved.
- Test carefully: With extreme caution, observe whether the blade stops immediately when the robot is gently lifted a few centimeters. If not, switch OFF immediately.
- Inspect lift sensor: Locate the lift sensor and its magnet under the chassis. Ensure the magnet is present and aligned with the sensor when the robot is on the ground.
- Check wiring: Verify that the lift sensor cable is securely connected to the main board and not damaged.
