 The RobotState component serves as a central component for storing all robot related data. For now this data covers the current joint angles of the robot.<br>
 The RobotStateComponent implements a KinematicUnitListener, hence it reacts on all joint updates that are reported by a KinematicUnit component. An exemplary startup script could look like this

 The RobotStateComponent provides several methods for accessing the current configuration of the robot and for getting a snapshot of the current state which is compatible with
 models of the Simox/VirtualRobot framework. With these models the whole functionality of Simox (http://simox.sf.net) can be used, e.g. IK solving, collision detection or motion and grasp planning.
