1. A method of determining a handover position of a gripping device, wherein the gripping device is assigned to a laboratory sample distribution system having a transport plane and a plurality of electro-magnetic actuators positioned below the transport plane and wherein the handover position is assigned to a handover electro-magnetic actuator, the method comprising:

  • grabbing, by the gripping device, a position determining device such that the position determining device is held fixedly by the gripping device, wherein the position determining device comprises a magnetically active device;

    positioning the position determining device, while being held by the gripping device, on the transport plane;

    activating the handover electro-magnetic actuator such that it generates a magnetic field interacting with a magnetic field generated by the magnetically active device such that an attractive force is applied on the position determining device;

    moving the position determining device, while being held by the gripping device, by the attractive force to a first position;

    detecting the first position; and

    determining the handover position based at least in part on the first position.
