Conceptual graph-based synthesis of robotic assembly operations

A method for robot program synthesis is developed. The conceptual graph-based approach is proposed for the development of a robot programming support system. The system provides a means toward automated conversion of a user´s request expressed in natural language to the appropriate conceptual model of the required task. This approximate model of the dynamically changing real world of robotic assembly incorporates the information necessary for understanding, planning, and sensory-guided performance of the required robotic task. The overall framework of the system is defined, and the authors present the first phase of an assembly program synthesis: request specification, planning of valid assembly sequences, and required resources determination. A case study illustrates the approach on a large family of multi-axisymmetric components
