Configuring a 2-Motor Drivetrain in VEXcode IQ (1st gen) – VEX Library

Using VEX IQ (2nd generation)? See this article.

When starting to program with VEXcode IQ, blocks from the Drivetrain category will not appear in the Toolbox until a Drivetrain has been configured.

You can only configure one Drivetrain per project.

If you are configuring a Drivetrain without a Gyro Sensor, see this article.

Adding a Drivetrain

To configure a Drivetrain, select the Devices button to open the Devices window.

Select the generation that you are working with.

Select “Add a device.”

Select 'Drivetrain 2-Motor.'
