    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: An on-off pilot stage valve arrangement for controlling at least one main stage valve. The on-off pilot stage valve arrangement includes a first pilot valve discretely operable between two states, an on and an off state, the first pilot valve having an input at which there is a first pressure and an output connected to the main stage valve, a second pilot valve discretely operable between two states, an on and an off state, the second pilot stage valve having an input at which there is a second pressure and an output connected to the main stage valve. Both the valves are configured to be set in one of the two states in case the arrangement loses power.

    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.
