Configure a Fake Servo

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

• Config Builder
• JSON Template

Navigate to the CONFIGURE tab of your machine’s page in the Viam app. Click the + icon next to your machine part in the left-hand menu and select Component. Select the servo type, then select the fake model. Enter a name or use the suggested name for your servo and click Create.

{
  "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.
