Configuring a 4-Motor Drivetrain (No Gyro) in VEXcode Pro V5 – VEX Library

The VEX Visual Studio Code Extension has replaced VEXcode Pro V5, which is now end-of-life.

VEXcode Blocks and VEXcode Text remain actively developed and supported for all VEX platforms.

When starting to program with VEXcode Pro V5, Drive and Turn commands will not appear in the Command Reference until a Drivetrain has been configured.

You can only configure one Drivetrain per project.

If you are configuring a Drivetrain with a Gyro Sensor, click here.

In this article, the default values in the Drivetrain Settings are for the VEX V5 Clawbot.

Adding a Drivetrain
