Detailed Description

A class that enforces constraints on the differential drive kinematics.

This can be used to ensure that the trajectory is constructed so that the commanded velocities for both sides of the drivetrain stay below a certain limit.

overridevirtual

Returns the max velocity given the current pose and curvature.

Parameters

pose	The pose at the current point in the trajectory.
curvature	The curvature at the current point in the trajectory.
velocity	The velocity at the current point in the trajectory before constraints are applied.

Returns: The absolute maximum velocity.

Implements frc::TrajectoryConstraint.
