Swerve Module Configuration

Swerve Module Configuration (module/x.json)

The swerve module configuration configures unique properties of each swerve module. It maps 1:1 with ModuleJson which is used to create SwerveModuleConfiguration. This configuration file interacts directly with swerve kinematics.

IF your angle motors spin out of control then you may need to invert them in inverted

IF your drive motors spin uncontrollably you may have the drive motor set to be the angle motor via the ID's. Be sure to check them!

Fields

NameUnitsRequiredDescription

drive

Y

Drive motor device configuration.

angle

Y

Angle motor device configuration.

encoder

Y

Absolute encoder device configuration.

inverted

Y

Inversion state of each motor as a boolean.

absoluteEncoderOffset

Degrees

Y

Absolute encoder offset from 0 in degrees. May need to be a negative number.

absoluteEncoderInverted

Bool

N

Inversion state of the Absolute Encoder.

location

Y

The location of the swerve module from the center of the robot in inches. +x is torwards the robot front, and +y is torwards robot left.

conversionFactor

MotorConfig Overrides the value in physicalproperties.json if present and not equal to 0.

N

OVERRIDE Conversion factor applied to the motor controller for the onboard PID, used to override this setting in swervedrive.json

useCosineCompensator

Bool

N

Disabled cosine compensation which scales the velocity of modules which are not completely aligned with desired angles by the cosine of the difference between the angles.
