TankDrive

abstract class TankDrive : Drive (source)

This class provides the basic functionality of a tank/differential drive using TankKinematics.

Parameters

kV - velocity feedforward

kA - acceleration feedforward

kStatic - additive constant feedforward

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

Types

TankLocalizer

Default localizer for tank drives based on the drive encoders and (optionally) a heading sensor.

class TankLocalizer : Localizer

Constructors

<init>

This class provides the basic functionality of a tank/differential drive using TankKinematics.

TankDrive(kV: Double, kA: Double, kStatic: Double, trackWidth: Double)

Properties

localizer

Localizer used to determine the evolution of poseEstimate.

open var localizer: Localizer

Functions

getWheelPositions

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

abstract fun getWheelPositions(): List<Double>

getWheelVelocities

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

open fun getWheelVelocities(): List<Double>?

setDrivePower

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

open fun setDrivePower(drivePower: Pose2d): Unit

setDriveSignal

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

open fun setDriveSignal(driveSignal: DriveSignal): Unit

setMotorPowers

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

abstract fun setMotorPowers(left: Double, right: Double): Unit
