Class DeadReckonerPoseProvider

java.lang.Object
  lejos.robotics.proposal.DeadReckonerPoseProvider

All Implemented Interfaces:

PoseProvider, MoveListener

public class DeadReckonerPoseProvider
extends Object
implements MoveListener, PoseProvider

A PoseProvider that keeps track of coordinates using dead reckoning, by monitoring Pilot movements. Question: What about a robot that is helped along with a Compass? Should the compass go in a DeadReckoner constructor, or a Pilot constructor? The PoseProvider seems more logical but Lawrie wants it to only accept a Pilot. Provisional name: DeadReckonerPoseProvider Alternate names: DeadReckonerPoseProvider, DeadReckoner, OrienteeringPoseProvider, OdometryPoseProvider
