METHOD AND SYSTEM FOR OPTIMIZING THE LAYOUT OF A ROBOT WORK CELL

摘要

The present invention relates to a method for optimizing the placement of a plurality of workstations (20a-d) in a workcell including an industrial robot (1 ) programmed to execute a sequence of tasks on the workstations, wherein each task contains a series of robot targets linked as one or several paths to be visited by the robot when executing the task at the workstation. The method comprises the following steps: a) defining a preferred region (36) within the reachable range of the robot, placing the tasks inside or as close as possible to the preferred region using an evaluation criterion and an optimization algorithm, and based thereon assigning to each workstation a position inside or close to the preferred region, b) determining by means of an optimization algorithm a best order of the workstations to be placed relative to the robot with regard to the robot performance and a defined order in which the tasks has to be executed, and based thereon adjusting the positions of the workstations, and c) adjusting the positions (x,y,z,a) of the workstations by means of an optimization algorithm configured to run the robot program iteratively in order to optimize the placement of the workstations with regard to the robot performance.
