Kinematics

object Kinematics

A collection of methods for various kinematics-related tasks.

Functions

calculateMotorFeedforward

fun calculateMotorFeedforward(vels: List<Double>, accels: List<Double>, kV: Double, kA: Double, kStatic: Double): List<Double>

Computes the motor feedforward (i.e., open loop powers) for the given set of coefficients.

fun calculateMotorFeedforward(vel: Double, accel: Double, kV: Double, kA: Double, kStatic: Double): Double

Computes the motor feedforward (i.e., open loop power) for the given set of coefficients.

calculatePoseError

fun calculatePoseError(targetFieldPose: Pose2d, currentFieldPose: Pose2d): Pose2d

Returns the error between targetFieldPose and currentFieldPose.

fieldToRobotAcceleration

fun fieldToRobotAcceleration(fieldPose: Pose2d, fieldVel: Pose2d, fieldAccel: Pose2d): Pose2d

Returns the robot pose acceleration corresponding to fieldPose, fieldVel, and fieldAccel.

fieldToRobotVelocity

fun fieldToRobotVelocity(fieldPose: Pose2d, fieldVel: Pose2d): Pose2d

Returns the robot pose velocity corresponding to fieldPose and fieldVel.

relativeOdometryUpdate

fun relativeOdometryUpdate(fieldPose: Pose2d, robotPoseDelta: Pose2d): Pose2d

Performs a relative odometry update. Note: this assumes that the robot moves with constant velocity over the measurement interval.
