Configure a Fake Gantry

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

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 gantry type, then select the fake model. Enter a name or use the suggested name for your gantry and click Create.

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

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

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

Test the gantry

Once your gantry is configured and connected, go to the CONTROL tab and click on the gantry’s dropdown panel.

Use the panel to adjust the position of the actuator on the axis and check whether it moves as expected.

If the gantry does not appear on the CONTROL tab, or if you notice unexpected behavior, check your machine’s LOGS tab for errors, and review the configuration.
