ROIS — Parameters for System Information component

In Table 7.34 “System Information”, “robot ref(List<RoIS_Identifier>)” is required for “robot_position”, same as person position data in "Person localization"
In addition, ”position_data” should be List<Data>.

A system may operate several robots in an HRI Engine when the engine has sub HRI Engines or it controls multiple robots. In this case, each robot position should be distinguished by robot's ID (i.e. robot ref). So the ordered lists of robot ref and position are returned as result parameters
