-=====  System architecture  ===== 
- 
-KnowRob is realized in a very modularized way. A base system, provides the basic reasoning capabilities and is largely independent of the domain of interest. It consists of Prolog, its semantic web library that serves for loading the OWL files, the Java/Prolog interface which serves for interfacing 
-existing libraries written in Java, and the system of computables described earlier.

-On top of it, the Knowrob-Base system represents general class knowledge of the household and kitchen domain in form of an ontology. This ontology provides the robot with the general terms it 'thinks' in. 
  
-Extension modules plug into the system and provide e.g. specialized reasoning capabilities or interfaces to external data, e.g. to read object detections from the vision system. These modules mainly operate on the level of instances.
