Abstract: An apparatus configured to handle an object in a contactless manner, the apparatus includes a carrying body having a carrying surface which is configured to be directed towards the object, the carrying surface being provided with a plurality of traction members and a plurality of overpressure members, each overpressure member being provided with at least one exhaust opening, each traction member being provided with an indentation and at least two suction openings that are arranged in the indentation, the at least two suction openings of each traction member being configured to generate a pressure gradient between them so as to create a traction fluid flow in the indentation in a direction substantially parallel to the carrying surface; and a pressure controller configured to control the pressure gradient between the at least two suction openings of each traction member.

Abstract: An electromagnetic actuator includes a first and second magnetic members that are displaceable relative to each other and are arranged to provide a magnetic circuit; and a coil configured to, in use, receive a current to generate a magnetic flux through the magnetic circuit, thereby generating a force between the first and second magnetic members in a first direction, the magnetic flux, in use, being transferred between the first and second magnetic members through a first surface of the first magnetic member and a second surface of the second magnetic member, the first and second surface being separated by an airgap, wherein the first surface and the second surface are arranged relative to each other such that an outer dimension of the first surface extends beyond an outer dimension of the second surface in a second direction substantially perpendicular to the first direction.Figure 1
