Configuring a 2-Motor Drivetrain (No Gyro) 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 with 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 Gear Ratio
  • Reversing a Drivetrain
  • Deleting a Drivetrain
  • Changing a Gear Cartridge

Once the Drivetrain has been configured, select “Done” to submit the device to the configuration or “Cancel” to return back to the Robot Configuration window.

Note: Selecting “Cancel” will undo any changes you have made to the device and will not be a part of the configuration.

Note: If you are not configuring the Drivetrain for a VEX V5 Clawbot or Speedbot, see the additional options below.


Changing a Drivetrain’s Port Numbers

You can change the size of the track width for the Drivetrain by entering the values in the number box and by selecting the drop down menu under “Track Width.” The track width is the measurement between the middle of the front left wheel to the middle of the front right wheel.

Note: The default values are for the VEX V5 Clawbot and Speedbot. If you are using the Clawbot or Speedbot, you do not need to change the values.


Changing a Drivetrain’s Gear Ratio
