  • Publication number: 20250100170
    Abstract: A method of indicating noise emissions of an industrial robot, including: obtaining at least one robot program containing commands to the industrial robot; obtaining a plurality of values of at least one robot-motion parameter; recording, for each of the values of the robot-motion parameter, an acoustic quantity indicative of noise emitted by the industrial robot while executing said at least one robot program; and displaying, by means of a graphical user interface on a visual display, a visualization of the acoustic quantity indicated as a function of the robot-motion parameter.

  • Patent number: 11938624
    Abstract: A parallel kinematic robot including a base unit, a platform movable in relation to the base unit about a plurality of main axes, two independently movable actuating arms connected between the base unit and the movable platform for moving the platform in relation the base unit, a tool holder rotatably connected to the platform to allow rotation of the tool holder in relation to the platform about a first auxiliary axis, a motor for driving the first auxiliary axis, located in the base unit, and a gear unit. The gear unit includes a first gearbox located in the base unit and a second gearbox located in the platform.

  • Patent number: 11167410
    Abstract: A telescopic shaft having a first shaft, a second shaft configured to enable a first relative movement in an axial direction between the first and second shafts, and a third shaft configured to enable a second relative movement in the axial direction between the second and third shafts, and a third relative movement in the axial direction between the first and third shafts. The second shaft is located between the first and third shafts. The telescopic shaft is configured to connect a base of a parallel kinematics robot to an end effector of the same for the purpose of transferring torque. By providing the telescopic shaft with more than two shafts with mutual relative movements between the same, an extension factor (the relation between the maximum and minimum lengths of the telescopic shaft) and by that the working area of the parallel kinematics robot can be increased.

  • Patent number: 9868205
    Abstract: A parallel kinematics robot has a first drive arm and a second drive arm, the two drive arms being crossed when the robot operates within its normal work area. The drive arms thereby occupy less space in a horizontal direction compared with a situation where the two drive arms point away from each other.
