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

When starting to program with VEXcode V5, Drive and Turn blocks 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 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

Button labeled 'Robot Config' for VEX V5, used for configuring robot settings in the VEXcode software.

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

You can change the wheel size for the Drivetrain by selecting the drop down menu under “Wheel Size.”

Changing a Drivetrain’s Track Width

Diagram showing track width measurements in inches and millimeters for V5 Robot Configurations, illustrating the dimensions relevant to V5 category specifications.

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.

Changing a Drivetrain’s WheelBase

Diagram illustrating the robot wheel base configuration for V5 robotics, showing dimensions and layout for optimal performance in robot design.

You can change the size of the WheelBase for the Drivetrain by entering the values in the number box and by selecting the drop down menu under “Wheelbase.” The Wheelbase is the measurement between the front and rear axles.

Changing a Drivetrain’s Gear Ratio
