【正文】 djacent workstations. The present invention includes a flexible body shop for assembling workpieces using a single or multiple robots and a single or multiple fixtures. The present invention includes movable material handling robots, and stationary material processing robots in bination at the flexible body workstation. The workstation can perform processing operations on multiple workpieces sequentially, and performs different processing operations through the workstation simultaneously. The material processing robots performing processing operations on the workpieces can be located adjacent the at least one processing path, or in between first and second processing paths and are independently movable relative to each other. The workpiece fixtures can be provided in the form of interchangeable end effecters connectable to the at least one material handling robot for holding and supporting different workpiece configurations by exchanging one interchangeable end effecter configuration for a different interchangeable end effecter workpiece configuration. The interchangeable end effecters can be geometry fixtures for different workpiece configura tions to allow processing different workpiece configurations in any desired sequence by changing end effecters automatically to correspond to the next workpiece configuration to be processed. The present invention can include a plurality of similar workstations positioned in sequence along an assem172。bly line. The at least one material handling robot can hand off a workpiece from a transfer position at one end of the processing path to another material handling robot for movement along another processing path for moving work172。ing any mix of workpieces of different configurations in any sequential order. The electronic control means can present the appropriate interchangeable end effecter for connection to a material handling robot in order to move the workpiece along a corresponding processing path to a processing position adj acent the processing path for interaction with the material processing robot or robots located at the processing position. The electronic control means can signal each material handling robot when an exchange of interchange172。 FIG. 2 is a simplified perspective view of the workstation according to the present invention with a first material handling robot at a loading position, a second material handling robot at a processing position, and material processing robots located adj acent the processing position in between the first and second processing paths followed by the first and second material handling robots。ing path 16a, 16b for supporting a workpiece 12 to be moved along the processing path 16a, 16b. The workstation can include at least one station defined by at least one processing position adjacent the processing path 16a, 16b for receiving workpieces 12 to be processed when delivered and posi172。porting a second workpiece 12b to be moved along the second processing path 16b. At least one stationary monu172。dling robot 16a, 16b can be supported for movement along at least one overhead rail location and/or at least one floor supported rail location. At least one material processing robot 20a, 20b, 20e, 20d can be located adjacent the processing position for processing workpieces 12a, 12b to be processed after being delivered by the at least one material handling robot 14a, 14b traveling along the corresponding processing paths 16a, 16b. Each material handling robot 14a, 14b can include an interchangeable end effecter 22 connectable to the material handling robot 14a, 14b for holding and supporting different configurations of workpieces 12a, 12b. The interchangeable end effecter 22 can be provided for holding, supporting, locating and/or geometry fixturing the corresponding workpiece 12a, 12b to be processed with the corresponding material handling robot 14a, 14b at the processing position 18. The interchangeable end effecter 22 can be floor mountable by the corresponding material handling robot 14a, 14b at the processing position. The interchangeable end effecter can define a geometry fixture tool 24 for accurately positioning the workpiece 12a, 12b to be processed with respect to the end effecter 22 thereby allowing the corresponding material handling robot 14a, 14b to accurately position the workpiece 12a, 12b and end effecter 22 in bination at the processing position in a predetermined location so that the material processing robots 20a, 20b, 20e, 20d can perform the processing operations with precise accurate positioning with respect to the workpiece. By way of example and not limitation, the material processing robots 20a, 20b, 20e, 20d can include welding robots for processing workpieces 12a, 12b of different configurations or body styles of automobiles to be assembled along the assembly line. The material processing robot 20a, 20b, 20e, 20d, can be supported from at least one overhead position and/or supported from at least one floor position. The present invention can include a method for processing a plurality of workpieces 12a, 12b. The method can include the steps of supporting a workpiece 12a, 12b to be mov
