Configuring a 4-Motor Drivetrain in VEXcode Pro V5

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 without a Gyro Sensor, click here. 

Here are the different options when configuring a Drivetrain without a Gyro:

  • Adding a Drivetrain
  • Changing a Drivetrain’s Port Numbers
  • Changing a Drivetrain’s Wheel Size
  • Changing a Drivetrain’s Track Width
  • Changing a Drivetrain’s Wheelbase
  • Changing a Drivetrain’s Gear Ratio
  • Reversing a Drivetrain
  • Deleting a Drivetrain
  • Changing a Gear Cartridge 

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


Adding a Drivetrain
