Servo motor breaks down

Using a mini production line with two servos

For example

First servo runs the conveyor belt

Second servo picks up the boxes from conveyer belt

If either one of the servo breaks down will the other servo still keep going?

Is there a way to connect them in a way if one stops working the whole production line will stop?

Thanks

Hello.

Typical hobby RC servos do not make their feedback available, so there is no way of knowing if they are responding to commands or not. So, if you want a system that uses more than one servo to stop if a single servo is not properly working, you will likely need to add your own hardware to monitor the behavior of the servos.
