  • Patent number: 11207781
    Abstract: Disclosed are systems and methods to provide a method for calibrating a touchscreen coordinate system of a touchscreen with an industrial robot coordinate system of an industrial robot for industrial robot commissioning and industrial robot system and control system using the same. In one form the systems and methods include attaching an end effector to the industrial robot; (a) moving the industrial robot in a compliant way until a stylus of the end effector touches a point on the touchscreen; (b) recording a position of the stylus of the end effector in the industrial robot coordinate system when it touches the point of the touchscreen; (c) recording a position of the touch point on the touchscreen in the touchscreen coordinate system; and calculating a relation between the industrial robot coordinate system and the touchscreen coordinate system based on the at least three positions of the end effector stylus and the at least three positions of the touch points.

  • Patent number: 8571706
    Abstract: A method for optimizing placement of a plurality of workstations in a workcell including an industrial robot programmed to execute a sequence of tasks on the workstations. Each task contains robot targets to be visited by the robot when executing the task. A preferred region is defined within the reachable range of the robot. Tasks are placed inside or as close as possible to the preferred region using an evaluation criterion and an optimization algorithm. The tasks are assigned to each workstation a position inside or close to the preferred region. A best order of the workstations and a defined order in which the tasks are to be executed are determined. The positions of the workstations are adjusted utilizing 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.
