# For the MRCU and OVR robots, are there any noise suppression tips we can use ?

## Use a noise filter or CR circuit to suppress the surge generated and cover the controller by a metal plate such as aluminum

1\. When relays or electromagnetic switches are used, use a noise filter or CR circuit to suppress the surge generated by these devices.  
2\. Cover the controller by a metal plate such as aluminum. This effectively shields the electrical  
noise emitted by the controller.
