Configure a Fake Servo

Configure a fake servo to test implementing a servo component on your machine without any physical hardware:

Navigate to the Config tab of your machine’s page in the Viam app. Click on the Components subtab and click Create component. Select the servo type, then select the fake model. Enter a name for your servo and click Create.

An example configuration for a fake servo in the Viam app Config Builder.

{
  "name": "<your-fake-servo-name>",
  "model": "fake",
  "type": "servo",
  "namespace": "rdk",
  "attributes": {}
}

No attributes are available for fake servos. See GitHub for API call return specifications.

Test the servo

After you establish the connection to your servo motor, navigate to the Control tab and select the dropdown panel dedicated to the motor. Use the buttons to move the servo motor to the desired angle.
