edu.wpi.first.math.trajectory.constraint.MaxVelocityConstraint

All Implemented Interfaces:

TrajectoryConstraint

public class MaxVelocityConstraint
extends Object
implements TrajectoryConstraint

Represents a constraint that enforces a max velocity. This can be composed with the EllipticalRegionConstraint or RectangularRegionConstraint to enforce a max velocity in a region.
