Method of positioning a carrier on a flat surface using a positioning member, wherein the carrier comprises an upper part and a base which are connected to each other such as to be arranged remote from each other, wherein the positioning member is arranged between the base and the upper part such that the base is located at an opposite side of the positioning member with respect to the upper part of the carrier, the upper part resting on the positioning member prior to placing of the carrier onto the flat surface, wherein the upper part comprises three engagement elements (14, 15, 16), and wherein the positioning member comprises a support surface for receiving the three engagement elements of the upper part, said support surface including a plurality of sockets (11, 12) forming a kinematic mount for said three engagement elements (14, 15, 16), wherein the base comprises three landing elements (25, 26, 27) at a side of the base facing the flat surface, each landing element (25, 26, 27) being associated with a respective one of the three engagement elements (14, 15, 16), and the method comprising the steps of: operating the positioning member for moving the carrier relative to the flat surface in a direction parallel thereto such as to position the carrier above a landing position; performing an action of placing the carrier on the flat surface at the landing position, said action of placing comprising: moving the base towards the flat surface until at least one of said landing elements (25, 26, 27) is in contact with the flat surface and an associated engagement element of said engagement elements (14, 15, 16) is released from the kinematic mount; continue said moving of the base relative to the flat surface until all landing elements (25, 26, 27) are in contact with the flat surface; and continue said action of placing the carrier until all engagement elements are released from the kinematic mount. wherein the carrier comprises an upper part and a base which are connected to each other such as to be arranged remote from each other, wherein the positioning member is arranged between the base and the upper part such that the base is located at an opposite side of the positioning member with respect to the upper part of the carrier, the upper part resting on the positioning member prior to placing of the carrier onto the flat surface, wherein the upper part comprises three engagement elements (14, 15, 16), and wherein the positioning member comprises a support surface for receiving the three engagement elements of the upper part, said support surface including a plurality of sockets (11, 12) forming a kinematic mount for said three engagement elements (14, 15, 16), wherein the base comprises three landing elements (25, 26, 27) at a side of the base facing the flat surface, each landing element (25, 26, 27) being associated with a respective one of the three engagement elements (14, 15, 16), and the method comprising the steps of: operating the positioning member for moving the carrier relative to the flat surface in a direction parallel thereto such as to position the carrier above a landing position;
