Claim 0:
1. A method for validating programmed process sequences or teaching programs of a robot configured with a robot controller, the robot being a physical robot mounted on or next to an injection molding machine and for extraction, handling, manipulation or further processing of injection molded parts that have just been produced, the method comprising:
storing data comprising process parameters, equipment features, and functionalities of the physical robot on the control side in a configuration file;
using the robot controller in creating a virtual robot from the stored data and applying it to a current teaching program in the robot controller to validate a process sequence of the robot controller, with a visualization of the process sequence being displayed directly on an output unit of the robot controller, with the virtual robot of any command line of the teaching program from the physical robot being decoupled and is used for the validation of certain commands and sub-sequences in the teaching program for potential collisions or incorrect behavior;
with the virtual robot following the physical robot in a coupled state and with decoupling, this synchronization between the virtual robot and the physical robot is stopped, with the coupled physical robot executing the current program sequence up to a possible collision situation and only then is switching made to the virtual robot with a simulation of dangerous states; and
with the virtual robot, after the decoupling at any time coupled with the physical robot, is coupled and reset to an initial state in order to then validate further sub-sequences of the teaching program.
