US Patent 9075034 Control method for computer-controlled liquid handling workstations

A control method for a computer-controlled liquid handling workstation which comprises a work surface, a motorized liquid handling robot with at least two pipettes each having a cone, and a control computer, to which the liquid handling robot is connected. A control program, activated in the control computer, enables the pipetting robot to position the pipette at specific positions on the work surface. The pipettes and at least one position are visualized as icons, using a visualization device. Upon selecting at least one pipette and designating a position, using an input mechanism, the selected pipette is moved down and up immediately after its selection, and moved to the designated position immediately after designating the position. These movements are carried out prior to selecting at least one action and its execution, enabling the operator to confirm the selection of the pipette and the designation of the position.
