-     * Detailed Description
+     * MMMPlayer reads an MMM trajectory from an MMM XML file (component property) and replays the motion using the KinematicUnit and its currently loaded robot.
+     * The trajectory can be replayed using position control or velocity control.
+     * In the latter case, the control parameters (P, I, D) can be configured via component properties.
