Abstract: A guide device for guiding a conduit or a medium includes a guide element which delimits a guide channel in which the conduit or the medium is accommodatable and guidable. The guide element has a first layer and a second layer which are disposed one inside the other, are pliable, and delimit a chamber system which is disposed between the first layer and the second layer. The chamber system has a plurality of chambers. The first layer and the second layer are impermeable to a fluid. By acting upon the chamber system with the fluid, the guide element, which is intrinsically pliable, is stiffenable and thereby converted into a rigid state.

Abstract: A feeding device for a manipulator arm has at least one joint, in particular of an industrial robot, having a flexible cable package via which at least one process medium can be fed at least substantially along the end effector of the manipulator arm and having a flexibly slack guide cover element enclosing the cable package. A stiffening device having a holding device is provided, which is arranged in a fixed position on the flexibly slack guide cover element. At least one stiffening element held by the holding device is provided, which, in an activated state of the stiffening device, is acted upon by stiffening energy such that the flexibly slack guide cover element and consequently the cable package are stiffened by the stiffening element.
