Conceptual Dependency Graphs and DJ

摘要

To make programming a robot easier, a language called DJ was designed. The language combined with information from a CAD system is used for the off-line programming of a flexible assembly cell. A program in DJ will look like an assembly instruction for construction kits. To represent the semantics of programs of the language DJ, conceptual dependency graphs are introduced. Conceptual dependency theory as a knowledge representation has some advantages. To make this representation suitable for robot programming, conceptual dependency theory was formalized and generalized. The knowledge representation thus obtained is called conceptual dependency graphs. The report will only concern user input for programming an assembly cell. First the framework, the language DJ and conceptual dependency graphs are described, followed by a sketch of how conceptual dependency graphs can represent DJ and an outline of a parser that transforms instructions in DJ into conceptual dependency graphs.
