The present invention relates to a method for determining the position of a robotic arm in an automatic liquid handling system in which a measurement probe with a first electrode is arranged on the robotic arm and, together with a second electrode formed by at least part of a working area or at least part of a container or container carrier forms a measurement capacitor that is operatively connected to a measurement unit for measuring an impedance, in particular a capacitance of the measurement capacitor. The method involves moving the measurement probe along a first path, detecting a first change in the impedance, in particular in the capacitance of the measurement capacitor at a first point on the first path, and defining at least one first reference spatial coordinate for a control unit of the robotic arm on the basis of the first point on the first path.
