If the servo is overloaded, it will jitter or even get blocked at the tipping point.

The servo may be faulty, please contact service@makeblock.com for further advice.


Pay Attention

Running a locked steering engine for too long can damage it. The heat generated by the blocked engine can cause it to burn out and fail.

Note: A locked rotor occurs when a steering engine is overloaded and cannot rotate. A steering engine normally experiences a certain amount of resistance or load during normal operation, but if the resistance or load is too great, the engine will lock up.

When a locked steering engine is running, it may make abnormal noises or vibrate. It will also not be able to rotate as expected, which could cause the device or system to malfunction.
