  • Patent number: 10150214
    Abstract: A robot and method for controlling an industrial robot, which has a first robot arm, a second robot arm, a joint defining a kinematic pair between the first and second robot arms, an actuator for generating relative movement between the first and second robot arms, and a robot controller for controlling the movements of the actuator. The method includes the steps of: determining a presence of a first torque indication at the actuator to be interpreted as a first command to the robot controller; repeatedly obtaining an external torque value (?ext) to obtain an external torque behavior; comparing the external torque behavior with the first torque indication; and executing a robot function corresponding to the first command upon detecting that the external torque behavior corresponds to the first torque indication. The obtained external torque behavior depends on a reference torque value (?ref) obtained from a dynamic model of the robot.

  • Patent number: 8588981
    Abstract: A system of manipulators including several manipulators, namely robots and/or external axes, such as workstations or transport tracks, whereby each manipulator is controlled by a control system via communication means and is programmed to carry out a plurality of tasks. The system of manipulators is movable in a first coordinate system. A second coordinate system is defined for each manipulator, so that one part of the manipulator, e.g. its tool center point, stands still in the second coordinate system, which is movable relative to the first coordinate system.

  • Patent number: 6418774
    Abstract: A device for calibration of an industrial robot, which calibration device is adapted for being in contact during the calibration with at least one plane of reference arranged on the robot, the calibration device includes an angle measuring member arranged for measuring an angle relative to the vertical line. The device further comprises two contact elements each having a curved surface, and the contact elements are arranged for being in contact with the plane of reference.
