The realistic robot simulation -RRS- interface

1994 , Bernhardt, R. , Schreck, G. , Willnow, C.

Tools for simulation and off-line programming became an important means for economic application of industrial robots. Until now the accuracy of simulation was not sufficiently precise for reliable down-load and execution of the off-line generated programs. A main cause for this was the controller specific motion behaviour of the robots that could not be simulated with sufficient accuracy. The RRS-project was created to overcome this deficite. By defining a suitable interface, it was made possible to integrate original controller software for motion behaviour into off-line programming systems.

Development demands for robotized manufacturing systems

1993 , Bernhardt, R. , Schreck, G.

Software tools for planning and simulations of robotized systems are commercially available and more and more used in industry. The intention of using these tools is to support the whole procedure form the selection of the robots and workcell components, the generation of all task programs down to the execution of the manufacturing task in the real workcell at the shopfloor. Additionally methods and tools concerning measurements, calibration, monitoring and diagnosis have to be considered. Today not all of the necessary steps for planning, implementing, operating and maintaining robotized manufacturing systems are adequately considered. In this article the principle demands for future developments are stated. Furthermore the R and D work which has been performed in this connection by the European Strategic Programme for Research and Development in Information Technology (ESPRIT), will be described on the basis of a few selected projects.

Knowledge based off-line programming of industrial robots

1988 , Schahn, M. , Schreck, G. , Bernhardt, R.

The paper presents a concept and a first realization of a knowledge based off-line programming system. The design is based on an already developed system which was also applied for relevant production tasks. A characteristic feature of the system is a production task specific, dialog oriented user interface. For a flexible realization of the user interface knowledge based approaches have been applied. A concept for a first realization is presented. (IPK)
