The invention discloses a full-automatic drink making robot. A stirring device is mounted at the tail end of one arm of a dual-arm robot, and a mechanical hand is arranged on the other arm of the dual-arm robot. An automatic cup discharging device separates a pile of paper cups, the paper cups are conveyed to preset grabbing positions, and the mechanical hand grabs the paper cups from the grabbingpositions. A self-service ordering system provides an ordering interface, customers select drink formulas from the ordering interface, a centralized control system acquires the drink formulas and carries out analysis, the tail ends of the corresponding mechanical arms of the dual-arm robot are controlled to be arranged on corresponding discharging points of a quantitative discharging cabinet sequentially according to the receiving sequence and the ingredient positions, and the quantitative discharging cabinet is controlled to carry out discharging according to the ingredient quantity. The stirring device stirs ingredients. The mechanical hand of the dual-arm robot is controlled to grab the paper cups from the preset positions, and the ingredients which do not need to be stirred are received. After the stirring device carries out stirring for preset stop time, drink is poured into the paper cups, the mechanical hand puts the paper cups at the preset positions on an automatic delivery device, and the automatic delivery device rotates to-be-delivered cup positions to the positions where the customers take the cups.
