Abstract: An apparatus for manipulating articles in which a multiaxial industrial robot is arranged on a travel unit and the industrial robot and the travel unit can be supplied with electrical energy via an energy storage unit. The travel unit has a control unit and at least three wheels having at least one drive unit, with the control unit being configured to rotate at least one of the wheels by the drive unit about an axis of rotation standing perpendicular on a symmetrical axis of rotation of the wheel and to rotate it about the symmetrical axis of rotation by the respective drive unit so that the apparatus can be moved in any direction by the travel unit. In addition, area monitoring sensors are arranged on at least two sides of the travel unit to monitor a virtual surface located at a predefined spacing next to and not intersecting the travel unit.

Abstract: An apparatus and a method for the removal of pellicles from masks which can be used for photolithographic purposes. The pellicles are removed from masks in a universal manner without them being further contaminated or damaged. In an apparatus, at least one grip is present for the manipulation of masks provided with pellicles which has at least two fixing elements which engage at the edge of a mask with exerted pressure force. There are moreover present in this connection at least one detector for the contactless determination of the position of mounts formed at the radially outer edge of pellicles, and a heating device for the heating of an adhesive with which pellicles are fastened to a mask with material continuity, and a removal apparatus of the pellicles from a mask having a mask fixing unit and a pellicle removal unit.
