  • Publication number: 20230219222
    Abstract: A robot controller is configured to control operation of at least one industrial robot. The robot controller includes: a processor; a memory configured to store a current system configuration of the robot controller, and an editing interface configured to enable modification of the current system configuration. It further includes a stored fingerprint corresponding to the system configuration according to original manufacturer settings; and a fingerprinting interface configured to facilitate computation of a fingerprint based on the current system configuration. The stored and computed fingerprints may be compared to determine whether any modification has occurred.

  • Publication number: 20230211501
    Abstract: A method of controlling a robot manipulator on the basis of a program containing a plurality of movement instructions. In the method, identification information related to a robot installation is obtained, and it is determined, on the basis of the identification information, whether any of the movement instructions relates to a location of the robot manipulator which is non-verified with respect to the robot installation, wherein a location is a pose, a path and/or a modulated path. If this is true, the method applies a policy which restricts execution of the program.

  • Patent number: 11376728
    Abstract: A method of handling safety in a working area of an industrial system, wherein at least one machine is arranged to operate in the working area, at least one manually operable safety input device is provided in the working area, and one or more of the at least one machine and the at least one safety input device is movable to different positions in the working area, the method including continuously or repeatedly determining whether one or more of the at least one the machine is in proximity to one or more of the at least one safety input device; and associating at least one machine with the at least one safety input device upon determining that one or more of the at least one machine is in proximity to one or more of the at least one safety input device, such that the at least one associated machine can be brought to a safe state by means of the at least one safety input device.

  • Patent number: 10888998
    Abstract: A method and a device for verifying one or more safety volumes for a movable mechanical unit positioned in an environment, wherein a world-coordinate system is defined in relation to the mechanical unit and in relation to the environment of the mechanical unit. The method includes storing a description of one or more safety volumes defined in relation to the world-coordinate system, and repeatedly determining position and orientation of a portable display unit in relation to the world-coordinate system, determining a graphical representation of the safety volumes based on the description of the safety volumes and the position and orientation of the portable display unit, overlaying the graphical representation of the safety volumes on a view of the real mechanical unit and its environment to provide a composited augmented reality image, and displaying the augmented reality image on the portable display unit.

  • Patent number: 10821610
    Abstract: A method of determining a joint torque in a joint of an articulated industrial robot, the robot having a first arm and a second arm which are coupled to each other by the joint and which are movable relative to each other by an electric drive unit coupled to the first and second arm, includes: controlling the electric drive unit by an electronic control device; assigning a measuring device to the electric drive unit, the measuring device measuring an electric current supplied to the drive unit; determining an actual value of the torque which is applied to the second arm from the measured electric current; and comparing, using the electronic control device, the determined actual torque value with a predetermined desired torque value for the joint.
