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.

Abstract: 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.

Abstract: A joint for transmitting movements between articulated elements of a parallel kinematics robot has at least two degrees of freedom and includes: a first housing, a second housing arranged rotatable in relation to the first housing about a first axis, and a shaft arranged rotatable in relation to the second housing about a second axis which coincides with a longitudinal axis of the shaft. The shaft is arranged rotatable in relation to the second housing by at least a first angular contact bearing. In applications where one of the revolute pairs of a joint is subjected to radial and axial forces of similar order, and another one is subjected almost solely to radial forces, it is advantageous to manage the forces of the prior by means of an angular contact bearing or bearings configured to bear both radial and axial loads, whereby a joint with very small backlash in a particularly compact design can be achieved.

Abstract: 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.
