The flexibility of industrial robot cells generally refers to the flexibility of the programmable handling devices, but not to the peripherals. However, with a large number of parts to bo supplied the peripherals account for the largest part of the investment expenditure. The following demonstrates a concept which, by using image recognition in parts supply and capture of gripping and component tolerances permits component-flexible parts supply capable of automatic changeover. Furthermore a process is demonstrated and examined which enables optimal gauging and assembly of toleranced parts with respect to cycle times. The realization of the concept and the application of the processes are described in a realized robot cell.
