<p>A device for torsion-proof connection of a number of elements (11, 12) in direct or indirect rolling contact with each other, which together make a robot arm or the like, whereby the elements are held together and actuated by force transmitting actuators, for example cords. The object of the present invention is to provide a device with which the individual elements of a robot arm can be torsionally locked so that it can bear significant torsional forces without detoriating the rolling characteristics of the elements. This object has been achieved by the fact that the elements (11, 12; 15) pairwise, with their rolling surfaces (13) turned towards each other, being connected with each other through a torsion member (14) which is flexible and/or joined in the rolling direction of the elements (11, 12) and which has a great stiffness across the rolling direction.</p> |
