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.

Seal arrangement () comprising a plug member () configured to seal a through opening () in a wall (); a pressing section (); and a cover member () configured to be connected to the plug member () and configured to force the pressing section () to press a sealing element (), arranged laterally outside the plug member (), towards the wall (). A kit of parts and a method for sealing a through opening () in a wall () and for painting the wall () are also provided.

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.

A shear pin for calibrating an industrial robot, the shear pin including an elongated body including a weakening defining a break location in case of overload. The shear pin is configured to be mounted to a calibration pin holder on the robot. A maximum force that the calibration pin can exert on the robot during calibration can be easily limited by dimensioning the weakening appropriately.

An arrangement for determining the calibration position of a robot joint where the joint has a moveable joint element and a stationary joint element, where one of the joint elements has a holding structure and the other a force providing protrusion, a robot controller, a motor connected between the robot controller and the moveable joint element and a force receiving element adapted to form a kinematic coupling with the holding structure and the force providing protrusion, where the kinematic coupling has at least two areas of contact between the structure and the force receiving element and one area of contact between the force providing protrusion and the force receiving element, the force receiving element being fastenable to the holding structure for stretching out across a gap between the two robot joint elements for receiving a force from the force providing protrusion.

An industrial robot including a contact panel having one or several contacts to allow connection to the industrial robot of one or several cables through which energy, signals or a substance may pass to and/or from the industrial robot. A cover forms part of an outer surface of the industrial robot. Each one of the one or several contacts of the contact panel protrudes through an opening in the cover so as to be accessible from the outside of the industrial robot. The contact panel is mounted to and supported by a holder that is secured in an internal cavity of the industrial robot so as to allow the contact panel to be held in place in the industrial robot when the cover is removed.

A device for adjusting the backlash in bevel gears in an industrial robot which includes a first conical gear wheel with a first axis of rotation and a second conical gear wheel. The device includes a displaceably arranged holder member adapted to fix and rotatably journal the first gear wheel for rotation about the first axis of rotation.

Robot arm

A method and apparatus for controlling the dimensions of an elongated material rolled in a rolling mill comprising at least two mill stands arranged after each other, each of said stands comprising two spaced rolls, said elongated material being fed between the rolls of each stand by rotating the rolls, wherein the material is subjected to stresses in the longitudinal direction thereof during the rolling operation. A rear portion of said material is subjected to an additional tension substantially in the longitudinal direction of the material when a rear end of the material is in the vicinity of a first stand and has not yet passed said stand.
