Abstract: The invention relates to an actuator device for use in a positioning system, wherein the actuator device is linearly movable within a plane with respect to a supporting structure of the positioning system as well as such a positioning system implementing such an actuator device. In an example of the actuator device according to the invention, it comprises a carrier having a longitudinal and a transversal dimension; and multiple groups of coil assemblies mounted in the carrier, each group of coil assemblies being structured to orientate the carrier in at least one degree of freedom. The single design actuator device according to the invention has limited constructional dimensions and allows high accuracy as to motion and position in multiple degrees of freedom.

Abstract: The invention relates to a linear guideway assembly for contactless linear displacement of a rigid body relative to another rigid body along a linear displacement path (x), said linear guideway assembly comprising: one, single rigid body formed as a linear guideway defining said linear displacement path as well as at least one rigid body formed as a product carrier being displaceable along said single linear guideway, wherein the linear guideway assembly further comprises multiple magnetic bearing assemblies for allowing contactless linear displacement of the at least one product carrier relative to the single, linear guideway, wherein all magnetic bearing assemblies are mounted to the product carrier in such way that the magnetic bearing assemblies are arranged in constraining five degrees of freedom (y, z, ?, ? and ?) of the product carrier relative to the single, linear guideway, whilst allowing one, translational degree of freedom (x) of the product carrier along the single, linear guideway, wherein all m

Abstract: The invention relates to a planar multi-joint robot arm system. An example of such planar multi-joint robot arm system comprises a base platform having a longitudinal axis, a product manipulator having a longitudinal axis perpendicular to the longitudinal axis of the base platform, a double crank-conrod mechanism consisting of a first crank-conrod link and a second crank-conrod link, wherein both the first and the second crank-conrod links having a crank end connected to the base platform and a conrod end connected to the product manipulator, and as well as a link element linking both crank-conrod joints of the first and the second crank-conrod links, a first driving unit arranged for rotating the crank end of the first crank-conrod link of the double crank-conrod mechanism, a multi-joint arm having first arm end connected to the base platform and a second arm end connected to the product manipulator as well as a second driving unit arranged for rotating the first arm end of the multi-joint arm.

Abstract: The invention relates to a magnetic bearing assembly for contactless linear displacement of a rigid body relative to another rigid body along a linear displacement path. The invention also relates to a linear guideway assembly implementing one or more such magnetic bearing assemblies.
