                                  double lateralMultiplier)

This class provides the basic functionality of a mecanum drive using class MecanumKinematics.

Parameters:

kV - velocity feedforward

kA - acceleration feedforward

kStatic - additive constant feedforward

trackWidth - lateral distance between pairs of wheels on different sides of the robot

wheelBase - distance between pairs of wheels on the same side of the robot

lateralMultiplier - lateral multiplier

Method Detail

getLocalizer

@NotNull
public Localizer getLocalizer()

Localizer used to determine the evolution of poseEstimate.

See Also:

poseEstimate

setLocalizer

public void setLocalizer(@NotNull
                         Localizer p)

Localizer used to determine the evolution of poseEstimate.

poseEstimate

setDriveSignal

public void setDriveSignal(@NotNull
                           DriveSignal driveSignal)

Sets the current commanded drive state of the robot. Feedforward is applied to driveSignal before it reaches the motors.

driveSignal

setDrivePower

public void setDrivePower(@NotNull
                          Pose2d drivePower)

Sets the current commanded drive state of the robot. Feedforward is not applied to drivePower.

See Also:

drivePower

setMotorPowers

public void setMotorPowers(double frontLeft,
                           double rearLeft,
                           double rearRight,
                           double frontRight)

Sets the following motor powers (normalized voltages). All arguments are on the interval [-1.0, 1.0].

getWheelPositions

@NotNull
public java.util.List<java.lang.Double> getWheelPositions()

Returns the positions of the wheels in linear distance units. Positions should exactly match the ordering in setMotorPowers.
