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.
