Title: SYSTEM AND METHOD FOR AUTOMATICALLY BREWING COFFEE
Abstract:
A system (10) and method for automatically brewing coffee. The system (10) comprises a console (101), a mechanical arm (102), and a coffee brewing utensil (103). After receiving a coffee brewing starting instruction, the console (101) generates a control instruction according to an obtained brewing action track of the mechanical arm (102). After coffee brewing is started, the mechanical arm (102) clamps a manual coffee brewing kettle (1031) to move according to the brewing action track of the mechanical arm (102) and performs manual coffee brewing simulation actions. An electronic scale (1034) collects the weight of a coffee liquid in a coffee cup (1033) in real time during the brewing and sends the weight to the console (101). The console (101) also generates a feedback control instruction according to the brewing action track of the mechanical arm (102) and the weight of the coffee liquid, so as to adjust the action of the mechanical arm (102), so that the movement of the mechanical arm (102) satisfies the brewing action track of the mechanical arm (102). By using the mechanical arm (102) and controlling the mechanical arm (102) to implement manual simulation actions to brew coffee according to the pre-obtained brewing action track of the mechanical arm (102), the problem of unstable coffee taste caused by human factors when baristas manually brew coffee and other factors is resolved.
