The invention describes a robot (5) and/or robot controller (17) and a method for validation of programmed workflow sequences or teaching programs (20) of a robot (5) preferably with a robot controller (17), wherein the robot (5) is preferably mounted on or next to a processing machine, in particular an injection molding machine (4), and serves for the extraction, handling, manipulation or further processing of injection-molded parts (3) which have just been produced. The travel parameters, equipment features and functionalities of the physical robot (5) are stored in a configuration file (27) on the control side. The robot controller (17) creates a virtual robot model (21) from these stored data. For validation of a workflow sequence, the robot controller (17) uses the current teaching program (20) in the robot controller (17) whereby the visualization of the workflow sequence is displayed directly on an output unit of the robot controller (17).
